The experience
Six and a half hours starting in the early afternoon, moving by speedboat instead of a long-tail boat so you reach snorkel spots farther from shore and get there fast enough to fit both a daytime dive and a night one. The boat holds up to 17 adults and 2 children, so it stays small. You'll stop at Railay Beach and Phra Nang Beach, the latter famous for Princess Cave, then move to Poda Island with its white sand and clear water, and Tup Island, three white sand islands connected by sandbanks at low tide.
The first snorkel happens during the day at a reef spot the guide picks based on conditions. After that, lunch is a buffet served on the beach with vegetarian options available if you request them ahead. Fresh fruit, water, soda and coffee come throughout the day. As the sun drops, you'll have a snack dinner, a club sandwich, at Phra Nang Beach or another spot around the islands, watching the light change. Then the second snorkel begins at night, when bioluminescent plankton light up as you move through the water, a sight you won't see on a daytime tour.
A professional certified guide leads both snorkels and gives a briefing on fish identification and safety before you enter the water. Life jackets and snorkeling gear are provided. National park fees and insurance are included. The tour runs subject to tides, weather and sea conditions, so the exact timing and stops can shift. Pickup is included from your hotel in Ao Nang, or from free meeting points near Krabi Resort or Nopparatara Pier. If you're staying in Railay, the boat picks you up from Railay West Beach for a separate fee.
Is this one for you?Book this speedboat tour if you want to snorkel two distant reef sites in one afternoon and catch the night bioluminescence. A long-tail boat is too slow to reach both spots before dark.

Top questions
What languages is the tour guided in?
Live guide in English, Spanish and Thai.
Can children come?
Yes. Ticket types: Child (4 to 12 years). Children under 4 can't be included in the booking.
What happens if it rains?
It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.
What's the bioluminescent plankton like when you snorkel at night?
Bioluminescent plankton glow in the water as you move through it, creating a light show that only happens after dark. The effect is strongest when conditions are right (calm water and no moon), and the guide times the night snorkel to maximize your chances of seeing it.
Do I need snorkeling experience to join this tour?
No prior experience is required. The guide gives a snorkeling and fish ID briefing before each snorkel, and life jackets are provided. Children as young as 4 can join if accompanied by an adult, though a moderate level of physical fitness is recommended for the full day on the water.
What islands does the speedboat visit?
The tour stops at Railay Beach and Phra Nang Beach in Railay Bay, then moves to Poda Island (known for white sand and clear water), and Tup Island, which is actually three white sand islands connected by sandbanks at low tide. The exact stops can shift based on tides and sea conditions.
Is lunch included, and what if I'm vegetarian?
Lunch is a buffet served on the beach and includes vegetarian options if you request them when you book. Fresh fruit, water, soda and coffee are available throughout the day, and you'll have a club sandwich snack at sunset.
Where does the boat pick me up?
Pickup is included from your hotel in Ao Nang, or from free meeting points outside Krabi Resort or at Nopparatara Pier. If you're staying in Railay, the boat picks up from Railay West Beach for a separate fee. Private transfers from Krabi Town, Klong Muang or Tup Kaek are also available for an additional charge.
How long does the whole tour take?
The tour runs 6.5 hours from the first pickup. Departure times vary by hotel location, with pickups starting around midday and the boat returning in the early evening after the sunset snack and night snorkel.
