Thailand is home to some of the world’s most beautiful islands, each offering its own unique charm, from lively nightlife and luxury resorts to quiet coves and untouched beaches. Whether you’re dreaming of island hopping through the Andaman Sea or relaxing on the Gulf of Thailand, there’s an island experience to suit every traveller.
Thailand Islands
Which are the best islands to visit in Thailand?
Thailand’s islands stretch across two coastlines – the Andaman Sea in the west and the Gulf of Thailand in the east. Each offers something special:
- Phuket is the most famous island, perfect for first-time visitors, families and those seeking a balance of beaches, culture and nightlife.
- Koh Samui is a tropical gem known for luxury resorts, palm-lined beaches and romantic getaways.
- Koh Phi Phi is a postcard-perfect paradise ideal for snorkelling, diving and scenic views.
- Koh Tao offers a diver’s haven with calm waters and colourful coral reefs.
- Koh Lanta is relaxed and family-friendly, boasting long beaches and fewer crowds.
- Koh Pha Ngan is famous for its Full Moon Party, but it is also home to serene beaches and yoga retreats.
- Koh Chang is a larger, less-touristed island with waterfalls, jungles and a laidback vibe.
Which Thai island is best for first-timers, couples or families?
- First-timers: Phuket or Koh Samui both have excellent infrastructure, international airports and a great mix of activities and relaxation.
- Couples: Koh Samui, Koh Lipe or Koh Yao Noi – Think romantic beachfront villas, sunset dinners and tranquil beaches.
- Families: Koh Lanta and Phuket offer safe swimming beaches, family resorts and easy access to attractions.
- Adventurers: Koh Tao or Koh Phi Phi are ideal for diving, snorkelling and exploring dramatic limestone landscapes.
Is island hopping easy in Thailand?
Yes, island hopping in Thailand is simple and scenic. Regular ferries, speedboats and domestic flights connect most major islands and coastal hubs.
- From Phuket, you can reach Koh Phi Phi or Koh Lanta by boat.
- From Krabi, hop to the nearby islands in the Andaman Sea.
- From Koh Samui, catch a ferry to Koh Tao or Koh Pha Ngan in just one to two hours.
Many tour operators also offer multi-island transfer passes, making it easy to explore multiple destinations in one trip.
When’s the best time to visit the islands?
Thailand’s islands enjoy warm, tropical weather year-round, but the best time to visit depends on the coast:
- Andaman Coast (Phuket, Krabi, Phi Phi, Lanta): November to April offers calm seas and clear skies.
- Gulf of Thailand (Koh Samui, Koh Tao, Koh Pha Ngan): January to August is ideal, with dry, sunny weather.
The monsoon months fall between May to October on the west coast and between October to December on the east coast. This is the low season, meaning that though beach conditions may not be optimal, there are fewer tourists around, making it a fantastic destination all year round.
Are there quiet, peaceful islands for relaxation?
Absolutely. Thailand is full of tranquil islands perfect for unwinding:
- Koh Yao Noi offers peaceful and picturesque, ideal for couples seeking seclusion.
- Hua Hin is an upmarket seaside town, once a fishing village, now offering luxury and charm.
- Khao Lak is famous for its pristine beaches, breathtaking landscapes and slower pace.
These islands offer serenity far from the crowds, without sacrificing comfort or natural beauty.
What are the best islands for snorkelling and diving?
Thailand is a diver’s paradise, with crystal-clear waters and thriving coral reefs. The top spots include:
- Koh Tao, one of the world’s most popular and affordable places to learn to dive.
- Koh Phi Phi boasts vibrant reefs and marine life around Maya Bay and Shark Point.
- Similan Islands is a protected national park known for world-class diving and visibility.
- Koh Lipe offers clear waters and colourful reefs ideal for snorkelling straight from the beach.
