Boat access and park entry are managed, so local trip timing matters.
Koh Kham is a protected underwater park off Sattahip with shallow coral gardens, clear water, and easy snorkeling that also works for beginner scuba. It is a managed Red Sea-style park where the appeal is color, shallow structure, and calm-water access rather than depth or drift. Visitors come for the compact coral reef, relaxed conditions, and the fact that the site is set up for low-stress day trips.
