How to Choose from Thailand’s Islands (Your Island Hopping Guide)

Thailand boasts over 1,000 islands, primarily clustered in the south along both the Gulf of Thailand (east coast) and Andaman Sea (west coast).

These islands cater to all travelers - from honeymooners and families to divers, backpackers, and party-goers. Island hopping offers the ultimate tropical adventure.

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

Things You Should Consider When You Pick Islands

When you choose islands in Thailand, there are some points you should consider:

• 1. Match the Island to Your Travel Style: Thailand's islands each boast distinct features: some pulse with vibrant nightlife and thrilling water activities, others offer serene retreats, while some are known for their luxury resorts and others for their natural escapes 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, like Koh Samui, Koh Phangan, and Koh Tao, are rainiest between October and November, while west coast islands, like Phuket and Krabi, are wettest between May and October.
• 3. Ease of Accessibility: Phuket and Koh Samui have international airports, more remote islands like Koh Lipe require multiple boat transfers.
• 4. Budget: The price differences between islands mainly come from beachfront resorts and high-end private villas, while downtown hotels show minimal variation. Additionally, peak season rates (especially Christmas and New Year) are typically 40-50% higher than regular season prices.

If you are seeking a relaxed, upscale island getaway with pristine beaches and a romantic atmosphere, Koh Samui is perfect for you. Compared to busier spots like Phuket, Samui offers more privacy and laid-back vibe—think boutique resorts, swaying palms, and tranquil shores.

Top 4 islands for Snorkeling and Diving

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

Koh Phi Phi —Pristine Coral Gardens Just a Boat Ride from Phuket

Best for: First-time divers, beginning snorkelers, and fans of The Beach scenery

Renowned for its stunning limestone cliffs and vibrant marine life, Koh Phi Phi is one of Thailand's top destinations for underwater adventures. The islands offer world-class snorkeling and diving sites, easily accessible from Phuket (1 hour by speedboat).

Here you could spot blacktip reef sharks at the shallow coral gardens at Shark Point, colorful clownfish at Bida Nok, and even bioluminescent plankton on night tours. Most sites are just a short boat ride from Tonsai Pier, with popular day trips covering Maya Bay and Bamboo Island's pristine sandbars.

Ideal for both beginners and advanced divers, Phi Phi offers varied underwater experiences. New divers can enjoy calm 5–12m dives at Viking Cave (home to reef sharks and turtles), while experienced divers explore the King Cruiser Wreck (25m) and dramatic walls at Kled Kaew.

Note: Phi Phi gets crowded from November to February for calm seas. It is wise to avoid crowds by booking early morning private longtail boats or staying overnight to visit popular sites like Maya Bay after day-trippers leave.

Koh Lanta —The Serene Diver's Retreat to See Whale Sharks

Best for: First-time divers, experienced divers and those who hate crowds

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

The island is particularly famous for its advanced dive sites like Hin Daeng's deep walls where manta rays glide by, and Koh Haa's fascinating cave systems sheltering leopard sharks. The beautiful shallow coral gardens at Koh Rok perfect for first-time divers.

This island is also ideal for couples who want serious diving without the crowds, as well as families with children aged 8 and up. Many resorts feature kids' clubs and family-friendly amenities. With over 20 professional dive schools along Long Beach and Saladan Pier, Koh Lanta offers everything from introductory courses to advanced certifications.

For the best experience, plan to stay 2-3 nights at Long Beach for easy access to dive shops or Kantiang Bay for a more secluded retreat. The prime visiting season runs from November to April when the seas are calmest, and visibility is at its best.

Koh Tao —The Diver's Academy

Best for: Experienced divers and beginners getting certified

Koh Tao is known as the dive capital of Thailand. It is considered one of the world's premier scuba training destinations to earn your scuba certification thanks to its affordable prices and excellent dive schools.

The island's waters are home to an abundance of marine life, including whale sharks. Popular dive sites like Chumphon Pinnacle and Sail Rock attract divers with their dramatic underwater landscapes and schools of tropical fish. A short boat ride away, Koh Nang Yuan's stunning sandbar is perfect for a half-day snorkeling excursion.

Similan Islands —The Bucket-List Dive Destination

Best for: Experienced divers and liveaboard adventurers

For serious divers, the Similan Islands should be on your top list. Located further from the mainland, these remote islands boast some of the healthiest coral reefs in the country.

Due to their protected status and distance, the best way to experience the Similans is on a multi-day liveaboard trip, allowing plenty of time to explore sites like Richelieu Rock and Elephant Head Rock. While there are no hotels on the islands themselves, nearby Khao Lak serves as a convenient base for arranging dive expeditions.

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

Top 2 Islands for Nightlife and Parties

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

Phuket: Diverse Nightlife for Every Taste

Phuket presents Thailand's most vibrant nightlife scene, blending world-class entertainment with upscale amenities. The island's nightlife district centers around Patong's Bangla Road.

Beyond the main entertainment zone, Phuket offers diverse options ranging from elegant rooftop bars with panoramic ocean views to refined beach clubs where you can enjoy sunset cocktails.

For a peaceful stay but easy access to nightlife, consider staying in Karon or Kata (just 20 mins to Patong). For ultimate luxury and privacy, Kamala or Surin beaches combine serenity with nearby entertainment options.

Koh Phangan: Beyond the Full Moon

Koh Phangan offers a more organic nightlife experience centered around its legendary Full Moon celebrations.

The main action happens on Haad Rin Beach, with vibrant parties at nearby venues. For visitors can't attend the monthly Full Moon Party, the island also hosts weekly jungle events like the Half Moon Festival. For families or couples seeking a relaxed atmosphere, the beach bars along Koh Phangan's northeast coast offer live music and mesmerizing fire shows.

For travelers seeking refined stays that balance tranquility with access to Koh Phangan's vibrant nightlife, consider the twin bays of Thong Nai Pan.

Thailand's Hidden Island Gems for Discerning Travelers

Koh Chang – The Untamed Jungle Island

Koh Chang offers a rare combination of lush rainforests and quiet beaches, perfect for nature lovers seeking an escape from crowds.

Unlike Thailand's more developed islands, Koh Chang maintains a wild charm with waterfalls like Klong Plu and hiking trails through Mu Ko Chang National Park. The west coast features serene beaches such as White Sand Beach and Klong Prao, where boutique resorts blend seamlessly with the natural surroundings.

For perfect day trip, you could start your days kayaking through lush mangrove forests or island-hopping to nearby Koh Wai and Koh Mak. By lunch time, savor fresh seafood at local fishermen's restaurants serving authentic Thai cuisine. For accommodations, choose between the laid-back vibe of Lonely Beach or the family-friendly resorts at Kai Bae Beach.

To reach Koh Chang, you could take a 30-45 minute ferry from Laem Ngop Pier (Trat Province) or a 1-hour speedboat from Ao Thammachat Pier (near Trat Airport), with both options offering frequent daily departures.

Koh Yao Noi & Koh Yao Yai – The Andaman's Peaceful Twin

These twin islands in Phang Nga Bay provide a tranquil retreat with stunning views of limestone karsts, minus the crowds of Phuket or Krabi.

Koh Yao Noi, the smaller and more developed of the two, offers luxury eco-resorts like Six Senses Yao Noi. One of the highlights of Koh Yao Noi is its Muslim fishing villages, giving you a glimpse of traditional Thai life.

The best way to explore these sleepy villages and their rubber plantations is by cycling. For more things to do, you can kayak at its hidden lagoons or just relax on untouched beaches.

Koh Yao Yai, even quieter, has long stretches of deserted sand like Loh Paret Beach. Both islands are ideal for couples seeking privacy or families wanting a slow-paced, culturally rich experience. Access is easy via speedboat from Phuket or Krabi (30-45 minutes).

Koh Lipe – The Maldives of Thailand

This small southern island sparkles with turquoise waters and powder-soft white sand. The main beach area buzzes with lively bars and boutique shops, while spots like Pattaya Beach and Sunrise Beach boast crystal-clear waters perfect for snorkeling right offshore. Unlike busier islands, Lipe maintains a laid-back charm, with no cars and just a few small resorts.

For more activities, the nearby Koh Adang and Koh Hin Ngam offer some of Thailand's best snorkeling opportunities (think clownfish, rays, and vibrant coral). For accommodation, consider staying at Sunrise Beach for sunrise views and direct beach access.

To reach Koh Lipe, take a 1.5-hour speedboat from Pak Bara Pier (Satun Province)
