Snorkeling in Krabi: Sunset cruise with bioluminescent swim

Four limestone islands, a reef full of small fish, and dinner on deck as the light turns gold

A 6-hour sunset cruise from Krabi aboard a traditional junk boat that visits Chicken Island, Poda Island, Tub Island, and Railay Beach, with snorkeling in clear water, a BBQ seafood dinner, and a final swim where bioluminescent plankton sparkles around you. Hotel pickup is included within Krabi Town, Ao Nang, Klong Muang and Tub Kaek. The boat carries life jackets, snorkeling gear, and an English-speaking guide. A National Park fee of 200 THB per adult and 100 THB per child is paid separately at entry.

The experience

The junk boat itself is the first thing that changes the day. Built for steadier sailing and more personal space than a speedboat, it has an open deck and lounge seating where the sea breeze flows while you relax between stops. The crew handles everything (briefing, snorkel setup, towels), so the rhythm stays unhurried from the moment you board.

The route sweeps through Krabi's signature landmarks in one arc. Poda Island appears first with bright white sand and clear water. Chicken Island follows, named for the chicken-shaped rock and famous for reef colors and small fish that make the snorkel feel alive. Tub Island sits on a sandbar that links to another island at low tide, creating shallow water where marine life gathers. Then Railay Beach rises with towering limestone cliffs framing the shoreline, and you settle into the deck lounge for photos as the light turns honey gold. Between stops, you float, snorkel, or cast a fishing rod if the mood strikes.

Dinner is where the day peaks. Fresh seafood hits the grill alongside Thai favorites and soft drinks while you sit on deck. The night ends with a final swim: the bioluminescent plankton moment the operator names as the highlight, where the water sparkles around you like drifting stardust. Onboard toilet and shower facilities are available, and seasonal fruit rounds out the meal.
