Thailand boasts over 1000 islands, mainly concentrated in the south along the Gulf of Thailand (east coast) and the Andaman Sea (west coast).

These islands offer something for every traveler – from honeymooners and families to divers, backpackers, and partygoers. Island hopping promises the ultimate tropical adventure.

No trip to Thailand is complete without an island stay. But with so many options, how do you choose the perfect islands for your itinerary?

Things to consider when choosing islands

When choosing islands in Thailand, you should consider a few points:

  • 1. Choose the island that suits your travel style: Thailand's islands each have their own unique characteristics: some pulsate with a vibrant nightlife and exciting water sports activities, others offer tranquil retreats, while some are known for their luxury resorts and others for their natural paradises and adventurous activities.
  • 2. Consider the season and weather: Thailand's east and west coasts are affected by the monsoon at different times. Islands on the east coast such as Koh Samui, Koh Phangan, and Koh Tao are rainiest between October and November, while the west coast, for example Phuket and Krabi, is rainiest between May and October.
  • 3. Accessibility: Phuket and Koh Samui have international airports, more remote islands like Koh Lipe require several boat transfers.
  • 4. Budget: The price differences between the islands mainly stem from beach resorts and exclusive private villas, while hotels in city centers hardly vary. Furthermore, prices during peak season (especially Christmas and New Year's) are generally 40–50% higher than in the off-season.

    • The 3 best islands for a beach holiday (well suited for families and couples)

    For most travelers planning a beach vacation in Thailand, Phuket, Koh Samui, and Krabi are at the top of the list. But how do you choose the right destination? Here's a brief comparison to help you find the perfect destination for your interests.

    1. Phuket – Lively beach atmosphere and diverse water activities

    Ideal for: Families and couples who want to have everything in one place.

    As Thailand's largest island, Phuket offers everything in one place: luxury resorts, a vibrant nightlife, family-friendly beaches, a wide range of water sports (snorkeling, jet skiing, stand-up paddleboarding, and surfing), and even cultural attractions. The island is perfect for families and couples seeking relaxation on the beach and adventures in the water.

    Families love the child-friendly beaches like Kata (gentle waves) and Karon (long sandy beach), while couples enjoy luxurious resorts and sunset cocktails on Kamala Beach. The island offers excellent restaurants and shopping and is an ideal base for day trips to the Phi Phi Islands.

    2. Koh Samui – Tranquil beach atmosphere and upscale resorts

    Ideal for: Couples and families who desire a quieter, more upscale atmosphere.

    If you're looking for a relaxed, exclusive island getaway with pristine beaches and a romantic atmosphere, Koh Samui is perfect for you. Compared to busier destinations like Phuket, Samui offers more privacy and a laid-back vibe – think boutique resorts, swaying palm trees, and tranquil beaches.

    Koh Samui offers beautiful beaches away from the hustle and bustle of Phuket. Chaweng Beach boasts fine sand and calm waters, while Lamai offers a more relaxed atmosphere. The island is ideal for couples seeking a romantic dinner by the sea or a spa getaway. Families appreciate the luxurious resorts with kids' clubs. Don't miss Ang Thong Marine Park for breathtaking island-hopping tours. (See our Koh Samui map for the exact locations of beaches, resorts, and island-hopping destinations.)

    Ideal for: Active couples and families with older children

    Krabi is known for its dramatic cliff scenery, exciting outdoor activities and secluded beaches, making it the perfect choice for nature and adventure lovers.

    Krabi may not be an island, but Railay Beach (accessible only by boat) feels almost like one. The impressive limestone cliffs and tranquil beaches are ideal for couples seeking privacy. Families with teenagers will love climbing, kayaking, and exploring hidden lagoons. For breathtaking sunsets, head to Railay West, and for exceptionally clear water, try Phra Nang Beach. It's significantly less crowded here than in Phuket or Koh Samui!

    The 4 best islands for snorkeling and diving

    For travelers seeking unforgettable underwater adventures, the following four islands offer some of the world's most spectacular marine landscapes. From vibrant coral reefs to exciting dive sites, each destination has its own unique charm.

    Koh Phi Phi – Pristine coral gardens, just a short boat ride from Phuket

    Ideal for: Diving beginners, snorkeling beginners and lovers of beach scenery

    Koh Phi Phi is known for its breathtaking limestone cliffs and diverse underwater world, making it one of Thailand's top diving destinations. The islands offer world-class snorkeling and diving spots and are easily accessible from Phuket in an hour by speedboat.

    Here you can observe blacktip reef sharks in the shallow coral gardens of Shark Point, colorful clownfish at Bida Nok, and even bioluminescent plankton on night tours. Most of these spots are just a short boat ride from Tonsai Pier. Popular day trips include visits to Maya Bay and the pristine sandbars of Bamboo Island.

    Phi Phi is ideal for beginners and advanced divers alike, offering diverse underwater experiences. New divers can enjoy calm dives at depths of 5–12 m in the Viking Cave (home to reef sharks and turtles), while experienced divers can explore the wreck of the King Cruiser (25 m) and the imposing drop-offs of Kled Kaew.

    Note: Phi Phi is very crowded from November to February due to the calm seas. It is recommended to avoid the crowds by booking private longtail boats early in the morning or staying overnight to visit popular attractions like Maya Bay after the day tourists have left.

    Koh Lanta – The tranquil diving paradise for whale shark watching

    Ideal for: Beginner divers, experienced divers and anyone who hates crowds

    For travelers seeking untouched underwater adventures, Koh Lanta offers some of Thailand's best diving and snorkeling spots in a relaxed atmosphere.

    The island is particularly known for its challenging dive sites, such as the steep walls of Hin Daeng, where manta rays glide by, and the fascinating cave systems of Koh Haa, which provide shelter for leopard sharks. The beautiful, shallow coral gardens of Koh Rok are ideal for beginner divers.

    This island is ideal for couples seeking undisturbed diving, as well as for families with children aged 8 and up. Many resorts offer kids' clubs and family-friendly facilities. With over 20 professional dive schools along Long Beach and Saladan Pier, Koh Lanta offers everything from introductory courses to advanced certifications.

    For an optimal experience, a stay of 2-3 nights in Long Beach, where dive schools are easily accessible, or in Kantiang Bay for a quieter and more secluded retreat is recommended. The best time to travel is from November to April, when the sea is calmest and visibility is best.

    Koh Tao – The Diving Academy

    Ideal for: Experienced divers and beginners getting their diving certification.

    Koh Tao is considered the diving capital of Thailand. Thanks to affordable prices and excellent dive schools, the island is one of the world's leading dive training destinations for obtaining your diving certification.

    The waters surrounding the island teem with marine life, including whale sharks. Popular dive sites like Chumphon Pinnacle and Sail Rock attract divers with their stunning underwater landscapes and schools of tropical fish. Just a short boat ride away, the breathtaking sandbar of Koh Nang Yuan offers ideal conditions for a half-day snorkeling excursion.

    Similan Islands – The diving destination for anyone who wants to experience it at least once in their life

    Ideal for: Experienced divers and adventurers with liveaboard dive boats

    For ambitious divers, the Similan Islands should be at the top of their list. These remote islands are located farther from the mainland and are home to some of the healthiest coral reefs in the country.

    Due to their protected status and remoteness, the Similan Islands are best explored on a multi-day diving safari, which allows ample time to visit landmarks such as Richelieu Rock and Elephant Head Rock. While there are no hotels on the islands themselves, nearby Khao Lak is an excellent base for diving excursions.

    Note: The Similan Islands are closed during the monsoon season (mid-May to mid-October) for safety reasons and to protect the marine environment.

    The 2 best islands for nightlife and parties

    For travelers seeking unforgettable evening entertainment, these two islands offer unforgettable adventures after dark.

    Phuket: Diverse nightlife for every taste

    Phuket offers Thailand's most vibrant nightlife, combining world-class entertainment with luxurious amenities. The heart of the island's nightlife is Bangla Road in Patong.

    Away from the main entertainment area, Phuket offers a wide range of options, from elegant rooftop bars with panoramic ocean views to exclusive beach clubs where you can enjoy cocktails at sunset.

    For a peaceful stay with good access to nightlife, Karon or Kata (just 20 minutes from Patong) are recommended. Those seeking ultimate luxury and privacy will find a perfect combination of tranquility and entertainment options nearby on the beaches of Kamala or Surin.

    Koh Phangan: Beyond the Full Moon

    Koh Phangan offers a more natural nightlife, the centerpiece of which is the legendary full moon celebrations.

    The vibrant life of Koh Phangan revolves around Haad Rin Beach, with lively parties at the surrounding venues. Those who can't make the monthly Full Moon Party can look forward to weekly jungle-themed events like the Half Moon Festival. Families and couples seeking a more relaxed atmosphere will find live music and captivating fire shows at the beach bars along Koh Phangan's northeast coast.

    For travelers seeking a sophisticated stay that combines tranquility with access to Koh Phangan's vibrant nightlife, the twin bays of Thong Nai Pan are worth considering.

    Thailand's hidden island gems for discerning travelers

    Koh Chang – The untamed jungle island

    Koh Chang offers a rare combination of lush rainforests and tranquil beaches, making it perfect for nature lovers looking to escape the hustle and bustle.

    Unlike Thailand's more developed tourist islands, Koh Chang has retained its wild charm, with waterfalls like Klong Plu and hiking trails through the Mu Ko Chang National Park. On the west coast, tranquil beaches like White Sand Beach and Klong Prao beckon, where boutique resorts blend harmoniously into the natural surroundings.

    For a perfect day trip, consider a kayak tour through lush mangrove forests or island hopping to the nearby islands of Koh Wai and Koh Mak. At lunchtime, you can enjoy freshly caught seafood and authentic Thai cuisine at local fishermen's restaurants. For accommodation, you can choose between the relaxed atmosphere of Lonely Beach and the family-friendly resorts on Kai Bae Beach.

    To get to Koh Chang, you can either take a 30-45 minute ferry from Laem Ngop Pier (Trat Province) or a 1-hour speedboat from Ao Thammachat Pier (near Trat Airport). Both options offer frequent daily departures.

    Koh Yao Noi and Koh Yao Yai – the peaceful twin of the Andaman Islands

    These twin islands in Phang Nga Bay offer a tranquil retreat with breathtaking views of limestone karst cliffs, far from the crowds of Phuket or Krabi.

    Koh Yao Noi, the smaller and more developed of the two islands, offers luxurious eco-resorts such as the Six Senses Yao Noi. Among Koh Yao Noi's highlights are the Muslim fishing villages, which offer a glimpse into traditional Thai life.

    The sleepy villages and their rubber plantations are best explored by bicycle. Those looking for more activity can kayak in the hidden lagoons or simply relax on pristine beaches.

    Koh Yao Yai is even quieter and offers miles of deserted sandy beaches like Loh Paret Beach. Both islands are ideal for couples seeking peace and seclusion, or families wanting a relaxing and culturally enriching stay. The speedboat transfer from Phuket or Krabi takes 30–45 minutes.

    Koh Lipe – Thailand's Maldives

    This small southern island boasts turquoise waters and powdery white sand. The main beach pulsates with life, featuring lively bars and boutiques, while beaches like Pattaya Beach and Sunrise Beach entice visitors with crystal-clear waters, ideal for snorkeling just offshore. Unlike busier islands, Lipe has retained a relaxed charm – there are no cars and only a few small resorts.

    For other activities, the nearby islands of Koh Adang and Koh Hin Ngam offer some of the best snorkeling in Thailand (think clownfish, rays, and vibrant coral). For accommodation, Sunrise Beach is recommended, offering sunrise views and direct beach access.

    To get to Koh Lipe, take a speedboat from Pak Bara Pier (Satun Province) in 1.5 hours.
