A steel-hulled longboat parts the Gulf of Thailand at dawn, the island-studded horizon sharpening as Koh Samui recedes.

Ang Thong was designated a national marine park in the late 20th century to conserve its islands, reefs and coastal forests, shifting the area from fishing use toward managed tourism and protection.
Visitors are asked to use reef-safe sunscreen, avoid stepping on coral, and follow park rules to limit erosion and protect nesting wildlife; guided tours help concentrate visitor impact.
