Thailand's islands feel effortless, but a few thoughtful habits protect the places you came to see. Carry a refillable bottle, avoid touching coral and follow local instructions when marine areas are temporarily closed.
Pack a light shoulder-and-knee cover for temples and local communities. On boats, keep a dry bag for electronics and avoid single-use plastics where practical.
Rules can change by park and season. Treat your guide's briefing as the final word on the day, especially for marine access and weather decisions.
