One hour across instead of two, and the whole day changes. You land while the big boats are still out there, which leaves room for the Emerald Lagoon, the Wua Talap climb, snorkelling and a proper paddle. Kayaks and lunch are in the price.
The lowest price we sell to Ang Thong, and the most room to spread out. A big boat takes about 90 minutes each way and trades speed for deck space and a steadier ride. Lunch and hotel transfers included. Kayaking costs extra.
Sixteen guests on a boat licensed for 25, running its own route instead of following the convoy. Lunch is at the sea-gypsy village on Koh Paluay and the park fee is already in the price. As close to private as you get without chartering.
Two hulls instead of one. You still cross fast, but without the spine-jarring slam of a monohull speedboat, and with room to sit like a human. Emerald Lagoon, snorkelling and kayaking all included.
Other tours hand you a kayak for twenty minutes and call it kayaking. Here the paddling is the day: several guided sessions through tunnels, overhanging rock and a hidden lagoon, with a 23-metre boat as your base. Park fee and lunch included.
You have probably already photographed the Red Baron from a Koh Samui beach without knowing you could sail on it. Twice a week the red-sailed junk runs to Ang Thong, built around comfort and food rather than a packed schedule. Park fee included.
