1. Koh Phi Phi

Day trips run to Maya Bay on Phi Phi Leh, made famous by the film The Beach. After years of overtourism, it was closed to let the reefs recover and reopened with strict limits, including a ban on swimming in the bay. Climb to the Phi Phi Viewpoint for the classic view of the twin bays.

There are no cars on Phi Phi Don, so you walk or take boats everywhere. Tonsai village, where the ferries arrive, is busy and noisy at night, while beaches like Long Beach and the north of the island are much quieter.

Getting there: Ferries run from Phuket and Krabi, taking around one and a half to two hours.
Time needed: Two to three nights.
Good to know: Maya Bay closes for part of each year so the reefs can recover, and a national park fee applies.
Insider tip: Climb to the viewpoint at sunrise, before the heat and the crowds.

Coast: Andaman. Best for: scenery and nightlife.

2. Koh Lanta

Koh Lanta is a long, laid-back island with wide sandy beaches and a relaxed atmosphere. It’s especially popular with families and couples.

The west coast is lined with beaches facing the sunset, from busy Long Beach to quiet Kantiang Bay. The Old Town on the east coast has wooden stilt houses and seafood restaurants. Mu Ko Lanta National Park at the southern tip has a lighthouse and jungle trails.

Day trips from Koh Lanta visit Koh Rok, with some of the best snorkelling in the area, and the Emerald Cave on Koh Mook, where you swim through a dark tunnel into a hidden lagoon. The island is long, so renting a scooter or car makes it easier to explore.

Getting there: Take a minivan and short car ferry from Krabi Airport, or a ferry from Phuket or Phi Phi in high season.
Time needed: Four to five days.
Best time to go: November to April.
Insider tip: Stay on the quieter beaches in the south of the island for a more peaceful trip.

Coast: Andaman. Best for: families and relaxing.

3. Phuket

Phuket is Thailand’s largest island and the easiest to reach, with an international airport and a huge range of hotels. It’s not a quiet island escape, but it offers convenience and variety.

Patong is busy and loud, while Kata, Karon and Kamala are calmer. Explore Phuket Old Town, with its colourful Sino-Portuguese shophouses, and visit the Big Buddha for views. Phuket is a great jumping-off point for boat trips to Phang Nga Bay and the Phi Phi Islands.

On Sunday evenings, the Lard Yai walking street market in the Old Town sells street food, crafts and souvenirs. Boat trips to Phang Nga Bay visit sea caves and limestone islands, including the famous James Bond Island.

Getting there: Phuket International Airport has flights from Bangkok and many international cities.
Time needed: Three to four days.
Good to know: Always wear a helmet and check your insurance before renting a scooter.
Insider tip: Stay in Kata or Kamala for a calmer beach base than Patong.

Coast: Andaman. Best for: convenience and day trips.

4. Koh Yao Noi

Koh Yao Noi sits in the middle of Phang Nga Bay, surrounded by towering limestone karsts. It’s a rural, mostly Muslim island where life revolves around fishing, rubber plantations and rice fields.

It’s quiet, with no big resorts or nightlife, which is exactly why people love it. Kayak among the karsts, cycle through villages and enjoy sunsets over the bay. It’s a short boat ride from both Phuket and Krabi.

Kayak trips explore the hidden lagoons of the nearby Koh Hong islands, and the calm, shallow bays are good for paddleboarding. Because the island is mostly Muslim, dress modestly away from the beach and be aware that alcohol is less widely available.

Getting there: Boats run from Bang Rong pier on Phuket in around 30 minutes, and from Krabi.
Time needed: Three days.
Insider tip: Rent a bicycle to explore the villages and rice fields at a slow pace.

Coast: Andaman. Best for: peace and authentic island life.

5. Koh Lipe

Koh Lipe is a small island near the Malaysian border, with powdery white sand and some of the clearest water in Thailand. It sits within Tarutao National Marine Park.

You can walk across the island in around 20 minutes. Snorkelling straight off the beach is excellent, and long-tail boats take you to nearby uninhabited islands. Getting there takes time, but that keeps it special.

In the evening, Walking Street comes alive with seafood barbecues, bars and small shops. Most businesses only open during the high season, so check that hotels and boats are running if you plan to visit outside November to April.

Getting there: Take a speedboat from Pak Bara pier, or island-hopping boats from Koh Lanta in high season.
Time needed: Three to five days.
Best time to go: November to April.
Insider tip: Take a long-tail boat trip to the nearby islands for snorkelling on quieter reefs.

Coast: Andaman. Best for: snorkelling and beaches.

6. Koh Samui

Koh Samui is the largest island in the Gulf of Thailand, with an airport, luxury resorts and a good mix of beaches. It’s well suited to couples and travellers who want comfort.

Chaweng is lively, while Lamai, Bophut and Maenam are quieter. Visit the Big Buddha temple, the Fisherman’s Village night market in Bophut and the Ang Thong National Marine Park, an archipelago of 40 or so islands for kayaking and snorkelling.

The Big Buddha temple, Wat Phra Yai, stands on a small island linked by a causeway, and the Friday night market in Bophut’s Fisherman’s Village is one of the best on the island. Samui has some of the most luxurious resorts in Thailand.

Getting there: Fly direct to Samui Airport, or take a ferry from Surat Thani.
Time needed: Four to five days.
Best time to go: January to August.
Insider tip: Book a day trip to Ang Thong Marine Park for kayaking and viewpoints.

Coast: Gulf. Best for: comfort and couples.

7. Koh Phangan

Koh Phangan is world famous for its Full Moon Party, held on Haad Rin beach each month, when thousands of travellers dance until sunrise.

But there’s more to the island than parties. The north and west coasts have quiet beaches, yoga retreats and jungle waterfalls. Bottle Beach, reached by boat or a steep hike, is one of the most peaceful spots in the Gulf.

The Full Moon Party date changes each month, so check the calendar if you want to go, or avoid those nights if you’d prefer peace. Thong Nai Pan in the northeast is one of the island’s prettiest bays, with calm water and a relaxed atmosphere.

Getting there: Ferries from Koh Samui take around 30 minutes.
Time needed: Three to four days.
Good to know: Never swim after drinking at the parties, and keep an eye on your belongings.

Coast: Gulf. Best for: parties and wellness retreats.

8. Koh Tao

Koh Tao is one of the most popular places in the world to learn to dive, with dozens of dive schools and affordable courses.

The island is small and rugged, with rocky coves and coral reefs close to shore. Most schools teach courses certified by PADI, the world’s largest diving training organisation. Hike to the John-Suwan Viewpoint and take a boat to Koh Nang Yuan, three tiny islands joined by a sandbar.

An open water diving course usually takes three to four days, and many dive schools include accommodation in their prices. Sairee Beach is the main strip, with bars and restaurants, while Shark Bay and Tanote Bay are good for snorkelling.

Getting there: Ferries run from Koh Samui and Koh Phangan, and catamarans from Chumphon on the mainland.
Time needed: Four to five days, including a dive course.
Good to know: Koh Nang Yuan charges an entry fee and doesn’t allow plastic bottles.

Coast: Gulf. Best for: diving and snorkelling.

9. Koh Kood

Koh Kood is a quiet, jungle-covered island near the Cambodian border, with clear water and very little development. It’s one of the least visited islands on this list.

Its beaches, like Klong Chao and Ao Tapao, are calm and beautiful, and inland waterfalls are great for a cool swim. Resorts are spread out, so it’s ideal for a peaceful retreat.

The Klong Chao waterfall is the island’s most famous, with a deep pool for swimming, and the quieter Huay Yang waterfall is reached on a short jungle walk. The island has few roads and little nightlife, which is exactly its appeal.

Getting there: Speedboats run from Laem Sok pier near Trat, which has flights from Bangkok.
Time needed: Three to four days.
Good to know: ATMs are limited, so bring enough cash.

Coast: Eastern Gulf. Best for: quiet nature.

10. Koh Chang

Koh Chang is Thailand’s third-largest island, covered in mountainous rainforest and fringed with long beaches. It’s within reach of Bangkok by road and ferry.

White Sand Beach is the main stretch, with plenty of hotels and bars. Head south for quieter spots like Lonely Beach and the fishing village of Bang Bao, built on stilts over the water. Trekking to inland waterfalls is a highlight.

Inland, the Klong Plu waterfall drops into a jungle pool and is one of the easiest to reach. The east coast is wild and quiet, with mangroves and small fishing villages, a contrast to the busier west.

Getting there: Car ferries run from the piers near Trat, around 30 minutes across. Trat is around five to six hours from Bangkok by road.
Time needed: Three to four days.
Insider tip: Have a seafood dinner on the piers of Bang Bao.

Coast: Eastern Gulf. Best for: easy access from Bangkok.

When Is the Best Time to Visit the Thai Islands?

The Andaman Coast (Phi Phi, Lanta, Phuket, Lipe, Yao Noi) is best from November to April, when the sea is calm and the sky is clear. From May to October, it’s monsoon season, with rough seas and some ferries suspended.

The Gulf of Thailand (Samui, Phangan, Tao) is best from January to August. Its main rainy season usually runs from October to December.

Koh Chang and Koh Kood are best from November to April.

Thailand is one of our top winter sun destinations, alongside the Canaries, Cape Verde and the Caribbean.

What Should You Know Before Island Hopping in Thailand?

Stick to one coast. Moving between the Andaman Sea and the Gulf takes most of a day.

Book ferries in peak season. Popular routes fill up around Christmas, New Year and Chinese New Year.

Pack light. Ferries, speedboats and long-tail boats have limited luggage space, and you’ll often wade ashore. A soft bag or backpack is far easier than a hard suitcase.

Respect marine parks. Don’t touch coral, use reef-safe sun cream and pay national park fees when asked.

Dress modestly in villages and temples. Cover shoulders and knees when away from the beach.

Carry cash. Smaller islands have limited ATMs.

A 2-Week Thai Islands Itinerary

Two weeks lets you see three or four islands on one coast without rushing.

Andaman Coast (November to April)

Spend three nights in Phuket, two on Koh Phi Phi and four on Koh Lanta, then finish with a few nights on Koh Lipe for the best snorkelling.

Gulf of Thailand (January to August)

Start on Koh Samui, take the ferry to Koh Phangan for a few nights, and end on Koh Tao, where you can learn to dive.

Getting Around the Thai Islands

Ferries and speedboats connect most islands, and combined bus and boat tickets make it easy to travel from the mainland. Book popular routes in advance during peak season.

Domestic flights to Phuket, Krabi, Samui and Trat save time on longer journeys. On the islands, taxis, songthaews (shared pickup trucks) and rented scooters are the main ways to get around. Only ride a scooter if you have the right licence and insurance.

How Much Does a Thai Islands Trip Cost?

Thailand offers excellent value, with affordable beach bungalows, street food and transport. Prices are higher on Koh Samui, Phuket and Koh Phi Phi, and during Christmas, New Year and Chinese New Year.

Long-haul flights are usually the biggest single cost. Once you arrive, you can travel comfortably on a modest budget, especially on quieter islands like Koh Lanta and Koh Yao Noi.

Where Should You Stay?

Choose a mix of busy and quiet islands. Phuket and Koh Samui offer the widest choice of hotels and resorts, while Koh Lanta and Koh Yao Noi have relaxed beach bungalows and family-friendly resorts.

On Koh Phi Phi, stay away from Tonsai village if you want a good night’s sleep. On Koh Tao, many divers stay at their dive school’s resort, often at a discount.
