Andaman Sea Marine Sanctuary
While strolling along peaceful coastal beach paths or exploring mainland cultural sites offers a gentle travel rhythm, visiting Phi Phi Island National Park delivers the quintessential, world-famous tropical marine adventure.

FAQ about Phi Phi Island National Park
How do I pay the national park entry fee?
Most speedboat tour operators collect the 400 Baht cash fee per person during morning check-in at the pier, though some high-end packages include it in the upfront price.
Can you swim at Maya Bay inside the national park?
No. To protect the blacktip reef shark nursery and delicate coral growth, visitors may walk along the shore and wade knee-deep into the water for photos, but full swimming is strictly prohibited in Maya Bay itself. Swimming is encouraged at nearby Pileh Lagoon and Bamboo Island.
What is the best time of year to visit?
The optimal visiting window is during the dry season from November to April, when the Andaman Sea is calm, clear, and ideal for boating and snorkeling.
