Krabi 7 Islands Tour & Bioluminescent Snorkelling — Ao Nang Day Trip
Hop a speedboat or longtail from Ao Nang and spend a sun-soaked day hopping between Poda, Chicken Island and Railay—then cap it with a possible night swim among glowing plankton. Practical, scenic, and ideal for snorkelers of all levels.
The Experience
Before You Go
Bring reef-safe sunscreen
Chemical-free sunscreen helps protect coral and is often required around fragile reefs; apply before boarding to avoid contamination.
Wear water shoes
Rocky shorelines and sandbars can be sharp and slippery—lightweight water shoes protect feet during beach entries and while walking Tub Island sandbars.
Charge your camera and bring a dry bag
Evening bioluminescent shots require a charged camera; store electronics in a dry bag to protect them from spray.
Monitor sea conditions and tides
Bioluminescence and snorkeling quality depend on calm seas and low light—check moon phase and weather to increase your chances.

Conservation Note
Visitors should use reef-safe sunscreen, avoid touching coral, and limit flash photography during bioluminescent swims to reduce disturbance to marine life.
The Krabi coastline is dominated by limestone karsts formed over millions of years; local communities around Ao Nang and Railay evolved from fishing and sea-trade economies.
