You step onto a wooden longtail as late afternoon sun chisels the limestone cliffs into sharp relief; the engine hums and the Andaman Sea carries you out past Ton Sai Pier. The boat slips into turquoise pockets between towering karst walls, and the air smells of salt, seaweed and fried coconut from nearby kiosks.

You step onto a wooden longtail as late afternoon sun chisels the limestone cliffs into sharp relief; the engine hums and the Andaman Sea carries you out past Ton Sai Pier. The boat slips into turquoise pockets between towering karst walls, and the air smells of salt, seaweed and fried coconut from nearby kiosks.
This half-day route hits the highlights: Monkey Beach’s white sand and curious macaques, Viking Cave with its high ledges where edible-nest swiftlet colonies have been harvested for centuries, and the narrow entrance into Pi Leh Lagoon, a carved-in basin ringed by sheer cliffs. Geologically these islands are ancient limestone uplift—limestone cliffs, collapse basins and submerged caves that concentrate marine life in sheltered bays. Culturally, Phi Phi’s fame widened after The Beach (2000), which brought international visitors and heavier management of Maya Bay.
Expect clear snorkeling at Pi Leh and Loh Samah, short swims from the longtail, and a slow evening cruise to watch the sun lower behind distant islands. As night falls the boat may drift for plankton-lit swimming — small neon sparks reacting to your movement.
Practical notes: check in at the Marlin Statue near Ao Ton Sai Pier at the time on your voucher; arrive 15 minutes early. Bring reef-safe sunscreen, quick-dry clothing, and a towel; life jackets and basic snorkel masks are provided. Sea conditions change fast—the operator can alter the route for safety. Mind the monkeys (don’t feed them) and follow crew guidance to protect coral and marine life.
easy.
5 hours.
Suitable for most fitness levels; requires basic swimming ability for snorkeling and short beach walks
The tour runs roughly 5 hours; scheduled departure is at 14:00 from Ton Sai Pier with check‑in between 13:30–14:00—confirm your exact pickup time on your voucher.
Yes, life jackets and basic snorkeling masks are provided; bringing your own mask/snorkel improves comfort and fit.
When conditions allow, the boat will stop after sunset for night swimming; the effect depends on plankton presence and sea conditions, which vary nightly.
Children aged 4–10 may join with a child ticket; supervise them closely during boarding, snorkeling, and on beaches, and use life jackets for open-water swims.
Viking Cave was the source of edible bird’s nest harvesting for centuries; swifts’ nest collection has shaped local livelihoods and island access.
Tour operators and authorities restrict access to sensitive sites like Maya Bay to protect corals and nesting sites—use reef‑safe products and follow crew instructions to reduce impact.
