Krabi snorkeling: 4 islands, sunset and bioluminescent swim
Snorkel three islands by day, then glow in the dark at night
A 6-hour snorkeling and sunset cruise in Krabi departs at 2 PM aboard a traditional wooden junk boat, visiting Koh Ya Wa Sam, Chicken Island and Poda Island for snorkeling, paddleboarding and kayaking, then returns to Railay Beach for a night swim in bioluminescent plankton. Small groups, Thai buffet dinner, all snorkeling gear, paddleboards and a kayak are included; guides speak English, Spanish and Thai.

The Experience
The boat leaves at 2 PM and heads straight to Koh Ya Wa Sam, one of the best snorkeling spots in the area. Plenty of coral and marine life sit in shallow water, and the crew keeps the group there long enough to snorkel, paddleboard, kayak or just float on deck. The itinerary shifts day to day depending on conditions—you might also stop at Ko Si and Ko Ta Ming—but the route always includes Chicken Island, where you can snorkel again or wade onto its white sand beach. Poda Island comes next, its limestone cliffs rising straight out of turquoise water.
As the sun sets, a Thai buffet dinner arrives on board (vegetarian and vegan options are there). The boat anchors near a small private beach depending on where the day has taken you. Once it gets dark, the crew takes you into the water for the night swim. The bioluminescent plankton glow when they move—every stroke of your arm, every kick leaves a trail of light. It's the kind of moment people describe to friends for years afterward.
The boat carries 6 paddleboards, a 2-person kayak, premium snorkeling gear with anti-fog masks and prescription options, life jackets in all sizes, and a freshwater shower. There's a shaded and sunny deck with comfortable seating and cushions. A cash bar sells drinks; water, juice, soft drinks, coffee, tea, snacks and fruit flow free. The crew speaks English, Spanish and Thai. Groups stay small—the boat runs with a minimum of 8 people, so you're never packed in.

Is this one for you?Book this if you want to snorkel multiple reefs in one afternoon and end the day in the water at night—the bioluminescent plankton glow only happens after dark, and the fixed 2 PM departure means both the reef time and the night swim fit into a single evening without you building the schedule yourself.

What's the water like for snorkeling at Koh Ya Wa Sam?
Koh Ya Wa Sam holds plenty of coral and marine life in shallow water, making it one of the best snorkeling spots in the area. The crew gives you plenty of time to explore the reef, and you can also paddleboard or kayak if you prefer to stay on the surface.
Can I bring my own snorkeling gear or do I have to use theirs?
Premium quality snorkeling gear is included—anti-fog masks, snorkels and fins—and prescription masks are also available. You're welcome to bring your own if you prefer it.
What happens during the bioluminescent swim at night?
Once it's dark, the crew takes you into the water near Railay Beach. The bioluminescent plankton glow when they move, so every stroke of your arm and every kick leaves a trail of light. It's a night swim surrounded by the glow, not a boat ride watching it from a distance.
Is the Thai buffet dinner included, and are there options for dietary restrictions?
Thai buffet dinner is included as the sun sets. Vegetarian and vegan options are available, and a cash cocktail bar sells drinks if you want something beyond the free water, juice, soft drinks, coffee and tea.
What should I bring and wear for this cruise?
Bring a towel, sunscreen and camera. Wear suitable clothing for wading in shallow water to get in and out of the long-tail boat that ferries you to the junk. It can get cool in the evening after swimming, so a warm top is a good idea.
How many people go on this cruise?
The boat runs with a minimum of 8 people and stays intimate with small groups. If the minimum isn't reached after confirmation, you'll get a full refund or alternate dates offered.
