Koh Phi Phi (Phi Phi Islands)

Operational Safety Basics

• Use a dive computer and stay well within no-decompression limits.
• Carry and know how to deploy an SMB. Boat traffic is constant.
• Listen to briefings about currents and exit points, especially at pinnacles and corners.

Environmental and Site-specific Hazards

• Surge can occur near limestone cliffs.
• Visibility can drop quickly after storms or in busy bays.
• Night dives and plankton tours should only run with calm seas and clear operator procedures.

Post-dive Planning

• Keep hydration high and avoid heavy drinking nights before diving.
• Respect flight-after-diving guidelines and allow adequate surface interval time before flying.

Phi Phi Don has basic clinics for minor issues, but serious cases usually require evacuation to Krabi or Phuket.

For dive injuries, Phuket is a key regional hub with hyperbaric medicine services. Bangkok Hospital Phuket lists a Diving Medicine Center with hyperbaric oxygen therapy and a diving physician on call. Bangkok Hospital Siriroj in Phuket also advertises hyperbaric services and emergency contact lines.

If you suspect decompression illness:

• Call local emergency services, alert your dive operator immediately, and administer oxygen if available.
• Do not delay seeking medical evaluation. Transport decisions should be guided by medical professionals.

Core Marine-park Rules You Should Expect

• No coral or shell collection.
• No standing on coral and no touching wildlife.
• No feeding fish.
• No anchoring on reefs, use mooring buoys.
• Restrictions on foam food containers and other common single-use plastics.
• Maya Bay is managed for recovery with timed entry and no swimming in the bay.

How to Be a Good Visitor

• Choose operators that brief reef etiquette and enforce it.
• Use reef-safe sunscreen or cover up with rashguards.
• Support beach cleanups if you are on the island for multiple days.
