A 10-hour yacht tour of Ang Thong Marine Park from Koh Samui with snorkeling, sea kayaking and visits to the Blue Lagoon, departing from Maenam Beach with hotel pickup included.

The experience
You start at Maenam Beach on the southwest coast of Koh Samui and sail past the Five Islands, where bird's nest harvesting still happens: a sight few visitors see. The yacht then enters Ang Thong Marine Park's archipelago, heading first to the most remote stop: a guided sea kayaking route along limestone cliffs, caves and tunnels that lead to a secret lagoon. If paddling isn't for you, the accompanying dinghy gets you there instead. This opening stretch sets the pace. You're moving through the park at a sailing yacht's speed, not the rush of a speedboat, so the landscape actually registers.
The snorkeling happens at Koh Wao, one of Thailand's top 20 reef sites and a destination only this non-speedboat vessel reaches. After a safety briefing, the crew fits you with full gear and leads you underwater to see the tropical reef. Non-swimmers and young children stay safe in the netted floating raft, which still gives a clear view of the marine life below. Lunch is a freshly prepared buffet served on deck as you cruise past Ko Lao Yu and the park's dramatic limestone formations. The meal happens while you're moving, so the scenery doesn't stop.
The final hours belong to the Blue Lagoon at Ko Mae Ko, the emerald-green saltwater lake enclosed by cliffs that inspired "The Beach." Because this yacht is the last boat allowed to visit, you arrive after all other organized tours have left. The viewpoint and beach are yours to explore without crowds. You can climb the steep stairs to the panoramic overlook of all 42 islands in the park, or stay on the secluded beach below. On the return to Koh Samui, you pass the sea gypsy community on Phaluai Island and finish the day with drinks and a banana split on deck, often watching the sunset over the water.
Is this one for you?Book this if you want to snorkel Thailand's best reefs without fighting crowds. The yacht arrives at Koh Wao after speedboats have cleared, and reaches the Blue Lagoon last, so you explore both at your own pace. The 10-hour day packs kayaking, two snorkeling stops and the park's most famous viewpoint into one trip, with meals and gear handled, so you're not piecing together a schedule between vendors.
