Ko Samui: Comfortable, Connected & Family-Friendly
📍 Gulf Of Thailandℹ️ Thailand’s second largest island — ideal for families and digital nomads, with great infrastructure and beach variety.
Ko Samui is Thailand’s second-largest island and one of the most convenient for travelers. It has its own airport, a wide range of hotels from hostels to five-star resorts, private hospitals, shopping malls, and great infrastructure. While parts of the island are very busy (like Chaweng), others offer a more peaceful escape (like Lipa Noi or Bang Por). The nearby Ang Thong Marine Park — featured in the photo above — is one of the region’s most scenic island getaways and can be visited on a day trip from Ko Samui.

This small island in the Gulf of Thailand combines laid-back beach life with a fun, social atmosphere that attracts young travelers, divers, and remote workers alike.

Ko Chang: Waterfalls, Jungle Adventures & Laid-Back Beaches
📍 Eastern Gulf Of Thailandℹ️ Thailand’s second-largest island, offering a mix of nature, relaxed beaches, and local charm — less crowded than Samui or Phuket.
⚠️ Important: The Dutch Ministry of Foreign Affairs has issued a code red travel advisory for islands near the Cambodia border, including Ko Chang. It is strongly recommended not to travel to these areas while this advisory remains in force.
Ko Chang (“Elephant Island”) is Thailand’s third-largest island and offers an appealing mix of nature, beaches, and infrastructure — without the overdevelopment of places like Phuket or Samui. Known for its dense jungle interior, cascading waterfalls, and long sandy beaches, Ko Chang remains laid-back while offering enough comforts for both short stays and long-term living.
Best Time to Visit
🌤️ November to April – dry season, with December to February the most popular
🌧️ May to October – monsoon season with heavier rains, but fewer tourists
Getting There
✈️ Fly to Trat Airport (TDX) from Bangkok (Bangkok Airways, ~1 hour), then take a 20-minute minivan + ferry transfer.
🚌 From Bangkok, buses and minivans (5–6 hours) depart regularly to Laem Ngop Pier (also called Ao Thammachat or Centre Point), followed by a 30–45 minute ferry ride.
🚗 Private taxis or rental cars are also an option for a more comfortable journey.
Layout & Vibe
The west coast is the most developed and ideal for swimming. White Sand Beach (Hat Sai Khao) is lively and popular, while Lonely Beach is backpacker-friendly and known for its nightlife. Kai Bae and Klong Prao are quieter but still accessible. The east coast is more local and remote, with fewer amenities but lovely views and hidden spots.
Things to Do
- Hike to waterfalls like Klong Plu and Than Mayom
- Snorkel or dive in nearby islets like Ko Wai or Ko Rang
- Explore the jungle interior by scooter or foot
- Take a Thai cooking class or enjoy sunset at a clifftop bar

- Mid-range: Nest Sense Resort, Kacha Resort, or Nature Beach Resort
- Budget: Bungalows in Lonely Beach or local guesthouses in Kai Bae
Food & Dining
From beachfront seafood shacks to high-end hotel dining, Ko Chang has variety. Don’t miss local seafood at Bang Bao Pier, or laid-back eateries in Kai Bae. Vegan and Western options are also available in most tourist areas.
Ko Mak: Eco-Escape with Coconut Groves & Zero Rush
📍 Eastern Gulf Of Thailandℹ️ A small, peaceful island with no big resorts or noisy nightlife — ideal for slow travel, nature lovers, and disconnecting.
⚠️ Important: The Dutch Ministry of Foreign Affairs has issued a code red travel advisory for islands near the Cambodia border, including Ko Mak. It is strongly recommended not to travel to these areas while this advisory remains in force.
Ko Mak is a small, eco-conscious island known for its quiet beaches, coconut plantations, and relaxed pace of life. It’s the perfect choice for travelers seeking a peaceful escape without the tourist buzz. Unlike larger islands, Ko Mak has no big resorts or nightlife — but what it lacks in size, it makes up for in charm, sustainability efforts, and authenticity.
It’s also one of Thailand’s most environmentally progressive islands, with local initiatives banning single-use plastics and promoting solar power and low-impact tourism. A true paradise for slow travelers, couples, and digital detoxers.
Best Time to Visit
🌤️ November to April – best for sunshine, swimming, and snorkeling
🌧️ May to October – rainy season; many resorts shut down and boat service may be limited
Getting There
✈️ Fly to Trat Airport (TDX) from Bangkok (Bangkok Airways, ~1 hour), then take a taxi or minivan to Laem Ngop Pier or Laem Sok Pier, followed by a speedboat to Ko Mak (~1 hour).
🚌 From Bangkok, buses and minivans (5–6 hours) run to the same piers in Trat, where you can connect with a speedboat to Ko Mak.
🚤 Island-hopping boats also link Ko Mak with Ko Chang and Ko Kood during high season — a great option for multi-island trips.
Island Layout
Only 16 km², Ko Mak is walkable and easy to explore by bicycle or scooter
Main beach areas:
- Ao Kao – long, calm beach with many resorts and restaurants

Ko Kood: Untouched Jungle, Waterfalls & Barefoot Luxury
📍 Eastern Gulf Of Thailandℹ️ One of Thailand’s most pristine islands, ideal for true tranquility seekers.
Ko Kood (also spelled Ko Kut) is one of Thailand’s most unspoiled and peaceful islands — a true hidden gem near the Cambodian border. With dense jungle, clear waterfalls, and postcard-perfect beaches, it’s ideal for travelers who want to disconnect from the world and enjoy nature in its raw beauty.
This is not a party island or a luxury destination (though a few upscale resorts exist). Instead, you’ll find a laid-back atmosphere with rustic charm, local fishing villages, and small resorts scattered along the coastline. It’s perfect for couples, nature lovers, and anyone seeking a tranquil retreat far from the crowds.
Best Time to Visit
🌤️ November to April – dry season with the best beach weather

🚤 Island-hopping connections are available between Ko Kood, Ko Mak, and Ko Chang during high season — perfect if you’re planning a multi-island itinerary.
Island Layout
Ko Kood is Thailand’s fourth-largest island, but much of it is untouched jungle.
Resorts and guesthouses are mostly along the west coast, particularly around Ao Taphao, Ao Phrao, and Klong Chao Beach.

Ko Samet: Bangkok’s Weekend Island Getaway
📍 Eastern Gulf Of Thailandℹ️ Popular with locals and expats for short beach breaks, thanks to its proximity to Bangkok and sunny climate year-round.
Ko Samet is a long-time favorite for both Bangkokians and tourists seeking a quick island escape. Located just 220 km from Bangkok, this compact island offers soft white-sand beaches, turquoise waters, and a blend of laid-back vibes with lively beach nightlife. While more developed than Thailand’s remote islands, it’s ideal for short getaways.
Best Time to Visit
🌤️ November to April – dry season and ideal for beach time
⚠️ Avoid weekends and Thai holidays if you prefer fewer crowds

Ko Lan (also spelled Koh Larn) is a small but popular island located just off the coast of Pattaya. Known for its surprisingly clear water and fine sandy beaches, it’s a great option for a spontaneous beach day or a short overnight trip from Bangkok or Pattaya. Expect crowds during weekends, but early mornings and weekdays can be peaceful.
Best Time to Visit

Budget-friendly: Guesthouses around Naban Pier and Samae Beach cater to local weekenders and backpackers.
💡 Insider tip: Start your day early to beat the crowds, and book ahead if visiting on weekends or Thai holidays as rooms fill up fast. For a quieter experience, consider staying overnight.

Phuket: Thailand’s Most Popular Island, with Something for Everyone
📍 Andaman Coastℹ️ Everything from luxury to party to hidden gems, all in one mega-island.
Phuket is Thailand’s largest and most visited island — and for good reason. It combines stunning beaches, luxury resorts, lively nightlife, local culture, and international conveniences all in one. Whether you’re here for beach-hopping, Muay Thai training, fine dining, or family fun, Phuket delivers a complete island experience.
⚠️ Note: This is a short overview. For full details on the best areas to stay, what to do, how to get around, and insider tips, read our dedicated guide:
🔗 Complete Phuket Travel Guide – Best Areas, Things to Do & Insider Tips »
While some parts (like Patong) can feel overdeveloped, there are still peaceful corners to discover, especially in the south and east. With an international airport and modern infrastructure, it’s ideal for longer stays or digital nomads needing strong connectivity.
Best Time to Visit
🌤️ December to April – dry season, ideal for beach days and boat trips
🌧️ May to October – green season: fewer tourists and lower prices, but expect occasional rain
Getting There
✈️ Fly to Phuket International Airport (HKT) — with direct connections to Bangkok, Chiang Mai, and major international cities. It’s the most convenient way to reach the island.
🚌 From Bangkok, long-distance buses take around 12–14 hours and arrive at the main terminal in Phuket Town.
⛴️ By ferry, Phuket connects to several islands including Ko Phi Phi, Ko Lanta, and Krabi (Ao Nang/Railay) — a great option if you’re island-hopping along the Andaman Coast.
Island Layout
Phuket is vast — with over 30 beaches and many distinct neighborhoods:
- Patong – nightlife, beach clubs, shopping malls
- Kata & Karon – good for families, surfing, and sunset views
- Rawai & Nai Harn – quieter, expat-friendly, local vibe
- Old Phuket Town – heritage architecture, art cafés, and night markets
Phuket is also the main gateway to several smaller islands, including the world-famous Ko Phi Phi.
Continue below for a look at Ko Phi Phi and Maya Bay, including the current visitor rules and whether it’s worth visiting post-recovery.
Ko Phi Phi: Postcard Beauty, Overcrowded Reality & Maya Bay Conservation
Once a backpacker paradise and now a household name thanks to “The Beach” (2000), Ko Phi Phi is a group of islands located in the Andaman Sea, reachable by ferry or speedboat from Phuket or Krabi. Despite its stunning natural beauty — including dramatic limestone cliffs, turquoise waters, and powdery beaches — the reality today is far more complex.
Overtourism and Overdevelopment
Ko Phi Phi Don, the only inhabited island, has suffered from mass tourism and rapid (often unregulated) development over the years. The once-sleepy village of Ton Sai is now densely packed with guesthouses, bars, and shops, catering to thousands of day-trippers and overnight tourists. Infrastructure struggles to keep up, and waste management remains a challenge.
If you’re seeking serenity or authenticity, this may not be the island for you. That said, it’s still a visually striking destination — and worth visiting if you manage expectations and avoid peak times.
Maya Bay: Beauty Under Protection
Maya Bay, located on the uninhabited island of Ko Phi Phi Leh, is arguably Thailand’s most iconic beach — a secluded cove framed by towering limestone cliffs, crystal-clear waters, and powdery white sand. But global fame came at a cost. By 2018, overtourism had severely damaged the ecosystem: coral reefs were destroyed, wildlife vanished, and the bay saw over 5,000 visitors per day.
In response, Thai authorities closed Maya Bay completely for over three years (2018–2022) to allow natural recovery. During this time:
- Damaged coral was rehabilitated through marine restoration projects.
- Shark populations returned (a key indicator of ecological health).
- Infrastructure was built to prevent future damage (e.g., floating piers, visitor caps).
🛑 Current Access Rules (as of 2025):
- Visitor numbers are strictly limited.
- Boats can no longer enter the bay directly.
- Visitors land at the rear pier and walk to the beach via a boardwalk.
- Swimming is currently not allowed to protect recovering marine life.
Should You Visit Ko Phi Phi or Maya Bay?
If you’re staying in Phuket or Krabi and want to see the scenery for yourself, a day trip to Maya Bay (with an ethical operator) can be worthwhile — especially if you value nature and want to support sustainable tourism efforts.
☝️ Be prepared for crowds even with the limits, and don’t expect solitude.
For those looking for a quiet beach escape, Ko Phi Phi Don is no longer the ideal choice. Instead, consider Ko Yao Noi, Ko Lanta, or the Trang Islands for a more peaceful island experience with similar landscapes but fewer people.
Ko Yao Islands: Secluded Luxury, Local Charm & Limestone Views
📍 Andaman Coastℹ️ Ko Yao Noi and Ko Yao Yai offer a peaceful escape between Phuket and Krabi, known for boutique resorts, local fishing villages, and stunning Phang Nga Bay views.
Tucked between Phuket and Krabi in Phang Nga Bay, Ko Yao Noi and Ko Yao Yai are a pair of tranquil sister islands known for their quiet charm, natural beauty, and boutique resorts. Despite their proximity to tourist hubs, they’ve remained refreshingly undeveloped. Think rubber plantations, rice paddies, friendly locals, and a pace of life that invites you to slow down.
Ko Yao Noi is the more developed and accessible of the two — popular with couples, digital detoxers, and those seeking understated luxury.
Ko Yao Yai is larger but even quieter, with long beaches and very few visitors. These are true escapes from the crowds.
Best Time to Visit
🌤️ November to April – dry season, calm seas, and beautiful weather — ideal for kayaking, island hopping, and beach stays
🌧️ May to October – off-season with occasional rain and fewer boats, but peaceful and relaxing if you don’t mind less-than-perfect weather
Getting There
✈️ Fly to Phuket (HKT) or Krabi (KBV) from Bangkok or Chiang Mai — both airports are well-connected and offer multiple daily flights.
🚤 From Phuket: Take a 30–40 minute speedboat from Bang Rong Pier (in the northeast of the island) to Ko Yao Noi or Ko Yao Yai. Ferries depart frequently throughout the day.
🛶 From Krabi: Boats leave from Tha Len Pier or Ao Thalane, taking about 30–45 minutes. This is a great option if you’re coming from Railay or Ao Nang.
💡 Insider tip: Make sure to confirm pier names and times in advance, especially during low season. Private transfers can also be arranged through most resorts for a more seamless journey.
Island Layout
Ko Yao Noi: Compact, with a paved ring road — easy to explore by scooter. East coast = sea views and resorts. West coast = rural villages and mangroves.
Ko Yao Yai: Much larger, with long, quiet beaches and very few developments. Ideal for exploring by motorbike if you enjoy untouched landscapes.
Things to Do
- Kayak through mangroves or around limestone karsts in Phang Nga Bay
- Explore by scooter — stop at rubber plantations and quiet beaches
- Take a longtail boat to nearby islets like Ko Hong or Ko Pak Bia
- Enjoy sunrise yoga or spa treatments at wellness-focused resorts
- Join a cooking class or batik workshop with local families
Where to Stay
- Ko Yao Noi:
- Luxury: Six Senses Yao Noi – an eco-luxury resort with panoramic views
- Mid-range: Paradise Koh Yao
- Budget: Sabai Corner Bungalows
- Ko Yao Yai:
- Luxury: Santhiya Koh Yao Yai – known for its dramatic wooden architecture and private beach
- Mid-range: Glow Elixir
- Budget: Koh Yao Yai Hillside Resort
Food & Dining
Local Muslim-Thai food is the norm — expect fresh seafood, roti, and spicy southern curries.
- Chaba Café and Gallery (Ko Yao Noi) – best coffee and vegan bites
- Kaya (Ko Yao Yai) – local dishes with sunset views
- Resorts often have excellent restaurants, with menus that blend Thai and Western
💡 Insider tip: Respect local customs — both islands have predominantly Muslim populations. Modest dress is appreciated outside the beach, and alcohol isn’t widely available outside resorts. Bring cash, as ATMs are limited.
Ko Lanta: Laid-Back Island Life with Sunset Views & Family Appeal
📍 Andaman Coastℹ️ Calm beaches, chill vibes, and great for long stays or exploring nearby islands.
Ko Lanta is a long, peaceful island off Thailand’s Andaman Coast known for its relaxed vibe, spacious beaches, and slower pace of life. Unlike more commercialized islands, Lanta offers an authentic, friendly atmosphere with a mix of Thai, Muslim, and expat communities. It’s popular with families, couples, and long-term travelers who want comfort without the crowds.
The island stretches from the bustling northern beaches near Saladan Pier to the remote and wild southern coastline. It’s the kind of place where you rent a scooter, find your favorite beach bar, and watch the sun melt into the sea — without ever needing to dress up.
Best Time to Visit
🌤️ November to April – dry season with the best weather and clear waters
🌧️ May to October – green season with more rain, rougher seas, and fewer tourists
Getting There
✈️ Fly to Krabi Airport (KBV) — then take a minivan or private taxi to the pier, followed by a short car ferry across to Ko Lanta. Total travel time is around 2–3 hours.
🚤 From nearby islands: Speedboats and ferries connect Ko Lanta to Phuket, Ao Nang, Railay, Krabi Town, and Ko Phi Phi, with travel times between 1–2 hours, depending on departure point and boat type.
🚗 By road: Because Ko Lanta is connected to the mainland via a short car ferry, it’s one of Thailand’s most accessible islands year-round — even during low season.
💡 Insider tip: During high season (Nov–April), speedboats are the fastest option. In low season, minivan + ferry transfers are more reliable due to weather.
Layout & Orientation
Ko Lanta Yai is where most of the tourist infrastructure is located.
- The north (Klong Dao, Long Beach) is more developed and family-friendly.
- The central and southern areas (Klong Nin, Kantiang Bay, Bamboo Bay) are quieter and more scenic.
Ko Lanta Noi is the smaller, more rural sister island, often skipped by tourists but great for local charm and cycling.
Things to Do
- Relax on wide beaches like Long Beach or Klong Nin
- Visit Mu Ko Lanta National Park with its lighthouse and hiking trails
- Explore Lanta Old Town, a charming fishing village with wooden houses on stilts
- Take a 4-island snorkeling tour to nearby Ko Ngai, Ko Mook (Emerald Cave), and Ko Kradan
- Try cooking classes, Thai massage, or take a Muay Thai lesson
Where to Stay
- Luxury: Pimalai Resort & Spa (Kantiang Bay) — a top choice for luxury-seekers and honeymooners
- Mid-range: Long Beach Chalet, Lanta Sand Resort, Lanta Castaway
- Budget: Coco Lanta, Thai House Beach Resort
Food & Dining
Ko Lanta has a wide selection of beachside restaurants, Thai eateries, and vegan cafes — especially around Long Beach and Old Town. Don’t miss:
- Kindee Restaurant – for upscale Thai fusion

The Similan Islands are a group of 11 small, uninhabited islands located in the Andaman Sea, known for crystal-clear waters, dramatic granite boulders, and some of the best diving and snorkeling sites in all of Southeast Asia.
As part of a protected national park, the islands are only open to visitors during the dry season and access is tightly regulated to preserve marine life.
📅 Current opening season: 15 October 2025 – 15 May 2026

Best Time to Visit
🌤️ Mid-October to Mid-May – the only time the islands are open to the public
🌊 December to April – best visibility and calmest waters for diving and snorkeling

💡 Insider tip: The Similan Islands are only open from mid-October to mid-May, with daily visitor numbers strictly limited for environmental protection. Tours sell out fast — especially from December to April and around Thai holidays — so book early with a licensed, eco-certified operator.

Railay & Ao Nang: Limestone Cliffs, Beach Caves & Rock Climber’s Paradise
📍 Andaman Coast (Krabi Mainland)ℹ️ Technically part of the mainland, but Railay is only accessible by boat from Krabi — and offers with Ao Nang an island-style experience with dramatic cliffs, soft sand, and laid-back beach life.
Though not technically islands, Railay Beach and Ao Nang offer an island-style escape thanks to their dramatic limestone cliffs, turquoise waters, and boat-only access (in Railay’s case). They’re ideal for travelers who want easy access from Krabi without sacrificing the tropical experience.
- Railay feels cut off from the world, only reachable by boat, with no cars and a mix of chilled backpacker bars and luxury resorts.
