Thailand’s Marine Parks
Southeast Asia Pilot – October 2025
Thailand’s Marine Parks – Preserving Paradise
Thailand’s marine parks are among the most beautiful in the world, from the granite boulders of the Similans to the emerald lagoons of Phang Nga Bay.

Fragile ecosystems
Yet these fragile ecosystems face pressures from mass tourism, overfishing and climate change. The Thai Marine Park authorities have started limiting visitor numbers, banning anchoring on coral, and enforcing seasonal closures. These measures have helped protect biodiversity while keeping the parks open to yachts.
Embrace the fees
Visiting skippers should be aware of fees and regulations – and embrace them as the price of preserving paradise. Sailing through these parks is a privilege.
Mooring yes – anchor no
Always pick up a mooring instead of dropping your anchor. If there is no mooring option, be careful to drop anchor away from all coral. Take nothing but photos and support local rangers where you can. The reward is clear: crystal waters, abundant marine life and bays that still feel like untouched sanctuaries.
