Snorkeling in Krabi: 7 Islands with Bioluminescence Plankton

Seven islands, sunset dinner, and glowing plankton in the dark

A seven-hour snorkeling tour from Krabi visits Tang Ming Island, Chicken Island, Tup Island, and Poda Island with a guide, then returns to Railay Beach after dark to snorkel bioluminescent plankton. You swim in the Andaman Sea at each stop, relax on white sand beaches, eat a barbecue dinner on Poda Island at sunset, and experience the rare glow of plankton that lights up when disturbed in the water.

The experience

You meet at Nopparat Thara Pier at 1 p.m. and travel by shared boat to Tang Ming Island, where you snorkel among tropical fish and clownfish in water about 300 meters deep. The route then stops at Puya Bay to rest on the beach, moves to Chicken Island for photos, and continues to Tup Island where you can walk across the sand to explore the connected islands and their golden beaches. Each stop is built around the water: you snorkel, swim, or simply float and watch the reef.

At 5 p.m. the boat reaches Poda Island, where you explore colorful corals and reef fish before settling on the white sand for a barbecue dinner as the sun sets. The meal is halal and includes drinking water and seasonal fruit. After dinner, the group travels to Phra Nang Cave and Railay Beach to photograph the landscape, then heads to a secret swimming spot near Railay where bioluminescent plankton glow in the darkness when you move through the water. This is the rare moment the tour builds toward: night snorkeling in water that lights up around you. The boat returns to Nopparat Thara Pier by 7:30 p.m. and drops you at your accommodation.

Hotel pickup is included for guests staying in Aonang, Krabi Town, or Klong Muang Beach. A professional certified guide leads the group in English or Thai, and all snorkeling equipment, life jackets, and travel insurance are provided. The boat is shared, so you travel with other guests rather than as a private group.

What is bioluminescent plankton and what does it look like when you snorkel at night?

Bioluminescent plankton are tiny organisms that glow blue or green when disturbed by movement in the water. When you snorkel through them after dark, your body and the water around you light up with each motion, creating an otherworldly effect that fades when the water stills.

What islands do you actually visit and what can you do at each one?

You stop at Tang Ming Island to snorkel, Puya Bay to rest on the beach, Tup Island to explore connected islands on foot and relax on golden sand, Chicken Island to photograph the landscape, Poda Island to snorkel corals and eat dinner at sunset, and Railay Beach for night snorkeling and photos of Phra Nang Cave.
