Kayaking Guidelines

Ninety percent of kayak-related incidents in Ao Phang Nga National Park trace back to three violations: paddlers removing life jackets in calm lagoons, touching cave walls coated in algae that takes decades to regrow, and entering hongs during outgoing tides when water levels drop too fast for safe exit. The marine park divides its waters into three kayaking zones. Green routes circle James Bond Island and Panak Island with minimal tidal variance and constant ranger patrols. Yellow routes thread through collapsed cave systems at Tham Lod and Hong Island where ceiling clearance changes by two meters between high and low tide. Red routes—closed to independent paddlers—protect nesting sites and require permit-holding operators with tide-table training. Paddling rules prohibit standing in kayaks, feeding macaques on cliff faces, and approaching long-tail boats closer than ten meters in the narrow channels between Khao Phing Kan and Ko Panyi. Rangers stationed at the Tha Dan checkpoint inspect every kayak for required safety gear before allowing bay entry. Cave kayaking demands specific conduct. Paddlers must maintain single-file spacing through low-ceiling passages, switch headlamps to red light when bats cluster overhead, and halt all forward motion when guides signal tidal-shift warnings. The lagoons inside collapsed caverns—hongs in Thai—flood through submerged tunnels that create unpredictable currents during the moon's second and fourth quarters. Kayaking guidelines require all groups to exit hongs thirty minutes before predicted tide peaks, the window when currents reverse direction and trap kayaks against tunnel ceilings. Mangrove channels around Ko Panyi enforce no-wake paddling to prevent root erosion, and limestone walls throughout the bay carry strictly-enforced no-touch policies after decades of algae damage from hands and paddle strikes. The Department of National Parks posts real-time tide tables and weather alerts at the Baan Tha Dan office, and rangers close yellow routes without notice when winds exceed fifteen knots or when storm cells approach from the Andaman Sea.
