Board a speedboat at Tonsai Pier and move from limestone lagoons to film-famous beaches before snorkeling among bioluminescent plankton at night. This afternoon-to-evening trip combines sightseeing, shallow-water swims, and a rare glowing-water experience.

The speedboat cuts a clean line across Andaman waters as the sun lowers, spray stinging your face and limestone cliffs throwing long shadows over turquoise bays. You hop between tiny islands—Monkey Bay’s rocky outcrops, the carved mouth of Viking Cave, the jewel-green water of Pileh Lagoon—each stop short and vivid before the boat pushes on toward a darkening sea where the plankton waits.

Wildlife
History
Phi Phi’s towering karst islands were formed from uplifted coral and marine sediment; modern tourism surged after the film set at Maya Bay drew international visitors.
Conservation
The area is in Hat Noppharat Thara–Mu Ko Phi Phi National Park; seasonal closures, park fees and no-swim rules at sensitive sites aim to reduce visitor impact and allow habitats to recover.

Bring a snug mask
A well-fitted snorkel mask keeps saltwater out and lets you focus on the glow rather than refitting gear in the dark.
Use reef-safe sunscreen
Apply biodegradable sunscreen before boarding to protect coral and marine life—reapply on the boat between swims.
Waterproof your valuables
Keep phones and documents in a dry bag; the plankton display is best experienced hands-on, and splash is constant.
Watch the tide and currents
Night snorkeling is in shallow, protected spots—follow the guide and avoid swimming alone when visibility drops.
Mask and snorkel
Helps you stay comfortable and observe marine life clearly during daytime and night swims.
Reef-safe sunscreen
Protects your skin and the local coral ecosystem—apply before boarding.
Lightweight rash guard or wetsuit top
Provides sun protection and a bit of insulation for evening swims.
Dry bag and headlamp
Keeps valuables dry and a headlamp helps on the boat after dusk without disturbing the plankton display.
