Koh Samui as Your Island Hub
One of Koh Samui's greatest advantages as a destination is its location. Sitting in the Gulf of Thailand, it's within easy reach of several other stunning islands — each with its own distinct personality. Whether you have a spare day or want to extend your trip, adding a nearby island to your itinerary is always worthwhile.
Koh Phangan
Just 15–20 km north of Koh Samui, Koh Phangan is famous the world over for its Full Moon Party — a monthly beach party on Haad Rin beach that draws tens of thousands of revellers. But there's much more to the island than that.
- Away from the party scene: The north and west coasts of Koh Phangan are peaceful, beautiful, and largely undeveloped. Thong Nai Pan Noi and Yai are two of the finest beaches in the entire Gulf of Thailand.
- Yoga retreats: Koh Phangan has become a major destination for yoga and wellness retreats, particularly around Srithanu on the west coast.
- Getting there: Regular high-speed ferries from the main pier at Nathon and from Maenam Pier take around 30–45 minutes. Multiple services daily.
Koh Tao
North of Koh Phangan, Koh Tao is small, hilly, and spectacularly beautiful. It is one of the world's most popular destinations for learning to scuba dive, thanks to clear, warm water and abundant marine life at relatively accessible depths.
- Diving: Dive schools line the main strip in Mae Haad. PADI Open Water courses are widely available and generally well-run. Chumphon Pinnacle and Sail Rock are among the top dive sites.
- Snorkelling: Even non-divers will find great snorkelling around the rocks of Shark Bay and Japanese Gardens.
- Getting there: High-speed ferries from Koh Samui take approximately 1.5–2 hours. The Lomprayah and Seatran services are the most reliable.
Ang Thong Marine National Park
This is arguably the most spectacular day trip from Koh Samui. Ang Thong is an archipelago of 42 limestone islands, completely uninhabited (except for a ranger station), with emerald lagoons, dramatic karst peaks, and some of the cleanest water in Thailand.
- Highlights: Kayaking through sea caves, climbing to the viewpoint on Ko Mae Ko for panoramic views, snorkelling in the natural saltwater lake
- How to visit: Most visitors take an organised day tour from Koh Samui, which includes boat transport, snorkelling gear, kayaks, and lunch. Tours depart from Nathon Pier and Maenam Pier.
- Best season: The park is closed roughly November to December due to weather. Check before booking.
Koh Nang Yuan
A tiny trio of islands connected by a white sand bar just off the northwest coast of Koh Tao. Day trips here are usually combined with a visit to Koh Tao. The snorkelling is excellent and the viewpoint hike is short but rewarding.
Planning Your Island Hops
Ferry Tips
- Book tickets in advance during peak season (Dec–Jan, Jul–Aug) as ferries sell out.
- The main ferry operators are Lomprayah and Seatran Discovery — both run reliable high-speed catamaran services.
- Check weather forecasts: during rough seas (especially October–November), services may be delayed or cancelled.
Suggested Itineraries
- 1 day: Ang Thong Marine National Park guided tour
- 2 days: Overnight on Koh Phangan — explore the north coast beaches and take a sunset yoga class
- 3 days: Koh Tao — complete a PADI Open Water course or dive multiple sites
Getting Back
All ferry routes between the islands are well served with return services. If you're combining a stay on another island with a flight home, it's worth noting that Koh Samui's airport is the only one in the group — plan your final night accordingly.
