About this tour
This 7–8 hour boat tour from Krabi takes you island-hopping across seven sites, culminating in a nocturnal swim through bioluminescent waters at Koh Raeng. Start with snorkelling at Yawasom Island and the dramatic Chicken Island rock, then explore the sandbar joining Tup and Mohr Islands and the quiet shores of Taming Island. Dinner is a buffet spread on Poda Island at sunset. The finale is otherworldly: wade into the plankton-lit sea at night, where your movements trigger an ethereal blue glow.
Highlights
- Snorkel vibrant reefs at Yawasom Island
- Iconic Chicken Island limestone formation
- Walk the natural sandbar between two islands
- Sunset buffet dinner on Poda Island
- Midnight swim in glowing bioluminescent plankton
What to expect
You'll board from your Krabi hotel or Ao Nang beach (other departures available at extra cost). The boat moves steadily between islands; expect calm conditions and shallow water for snorkelling. Mid-afternoon brings the sandbar walk—worth doing at low tide for the best experience. Dinner on Poda Island is a proper spread of local dishes, fresh fruit, and water. As darkness falls, the crew takes you to Koh Raeng for the main event. The bioluminescence isn't guaranteed every night and depends on plankton levels, but when active, it's genuinely striking. Most swimmers find the water warm and the experience meditative rather than thrilling.
