The Experience

The boat leaves the pier at 2pm after hotel pickup, giving you five hours on the water across seven stops. Tup Island and Chicken Island are the first pair—at low tide the sea recedes enough to expose a natural sandbank connecting them, so you can walk between the two on sand that appears only when the water pulls back. Chicken Island gets its name from a rock formation at its peak; it's a strong snorkeling spot. Poda Island has a wide white beach for swimming and sunbathing, while Taming Island and the Si Islands offer more reef snorkeling where clownfish and other coral dwellers are common.

The boat circles Pranang Cave in the late afternoon, and this is where night snorkeling happens if conditions allow—the bioluminescence that makes the water glow is a natural phenomenon that depends on the weather and the particular day, so it's not guaranteed but worth the chance. Railay Beach is the final stop, where a buffet BBQ dinner waits on the sand, followed by a fire show before the return trip to your hotel around 7pm.

The tour runs six to seven hours total. You get a life jacket and snorkeling mask for the day, drinking water and fresh fruit throughout, and a guide who speaks English and knows the islands. The speedboat is the transport for the whole group, so the pace is set by the boat's schedule and the stops themselves—you're not arranging pickups between islands or timing your own snorkeling sessions. Weather and sea conditions can shift the order of stops or change which islands the boat reaches, so the itinerary is flexible by design.

Top questions

What happens at Tup Island and Chicken Island when the tide goes out?

At low tide, the sea recedes and exposes a natural sandbank that connects Tup Island and Chicken Island, allowing you to walk between them on sand that only appears when the water pulls back. Chicken Island is also a strong snorkeling site.

Is the bioluminescent swimming guaranteed on this tour?

Bioluminescent swimming depends on weather and sea conditions, so it's not guaranteed every day. When conditions are right, night snorkeling around Pranang Cave lets you swim in glowing water, but the tour operates without it if the weather doesn't cooperate.

What's included in the dinner at Railay Beach?

Dinner is a buffet BBQ served on the beach at Railay, the final stop before the return to your hotel. Drinking water and fresh fruit are provided throughout the day as well.

Do I need to arrange my own way to the pier, or is pickup included?

Hotel pickup from Krabi Town or Ao Nang is included in the tour price. The boat departs at 2pm after a midday pickup, and you're returned to your hotel around 7pm.

Can children join this tour?

Children aged 4 to 11 are welcome on the tour. A life jacket and snorkeling mask are provided, and the pace is set by the boat's schedule across the seven islands.

What snorkeling gear do I need to bring, or is it provided?

Snorkeling masks and life jackets are provided as part of the tour. Bring swimwear, sunscreen and a towel; the boat supplies drinking water and fruit throughout the day.
