Why Choose a Cruise to Koh Samui?
Koh Samui is Thailand's second largest island, with a circumference of about 70 km. It is part of an archipelago of over 80 islands scattered in the Gulf of Thailand, only a handful of which are inhabited. It is precisely this island richness that makes cruising the ideal format to explore this region: from the deck of a boat, the landscapes change at each stop, between tropical forests, limestone cliffs, and lagoons with emerald reflections.
The island itself deserves attention before setting sail. Its most famous beaches, Chaweng and Lamai, stretch along the east coast and attract travelers from around the world. But the north and west coasts, more discreet, offer much more soothing atmospheres. The hinterland, meanwhile, is covered with coconut groves, pineapple plantations, and accessible waterfalls by foot. Koh Samui is not just a starting point, it's a destination in its own right.
Opting for a cruise to Koh Samui also means choosing freedom of movement that a hotel cannot offer. Each morning, a new island, a new beach, a new panorama. And each evening, the sunset from the deck of the boat, with its orange hues reflected on the calm waters of the gulf.
What Islands to Discover on a Cruise from Koh Samui?
The archipelago surrounding Koh Samui is full of islands with distinct characters. Here is an overview of the must-see destinations to integrate into your itinerary, according to your desires.
The Ang Thong National Marine Park
About 30 kilometers northwest of Koh Samui, the Ang Thong National Marine Park stretches over more than 100 km² and includes 42 islands. It is one of the most spectacular natural sites in the Gulf of Thailand. The limestone cliffs dive directly into the sea, caves open onto secret beaches, and the famous inner lake, nicknamed the Emerald Lake, offers a spectacle hard to forget.
From a sailboat or a catamaran, access to some coves of Ang Thong is done by dinghy or kayak, which allows exploring nooks inaccessible to large vessels. The seabed, rich in corals and tropical fish, also makes it a very popular snorkeling spot.
Koh Phangan, Koh Tao, and Koh Nang Yuan
Further north, Koh Phangan is known for its wild beaches and sunsets on the west coast, far from the hustle of its festive evenings. A stopover by sailboat allows you to discover its most serene side, that of isolated bays and fishing villages.
Continuing north, Koh Tao is a 21 km² island renowned worldwide for the quality of its waters and the diversity of its seabed. It's one of the best destinations for snorkeling and scuba diving in Southeast Asia. Right next door, Koh Nang Yuan is a unique site formed by three islets connected by white sandbanks. The view from the top of the island, after a short climb, is breathtaking.
What Activities to Plan During Your Cruise to Koh Samui?
A cruise to Koh Samui is not just a crossing. It's a program of varied activities, to be composed according to your desires and your pace. Here are the most enjoyed experiences by travelers in this archipelago:
- Snorkeling and free diving in the crystal clear waters of Ang Thong or around Koh Tao;
- Sea kayaking to explore the caves and hidden coves of the marine park;
- Hiking on the islands to reach panoramic viewpoints of the archipelago;
- Tasting the local Thai cuisine in fishing villages;
- Watching the sunset from the deck of the boat, facing the Gulf of Thailand.
