National park day-boat access is the practical way to run the site.
Koh yak - Koh rang national park is a small reef island with a shallow coral garden on one side and a slightly deeper coral face on the other. It is an easy boat-based day trip rather than a technical reef, so the dive stays relaxed when the weather is settled. Beginners, snorkelers, and newer divers come here for bright coral, mild current, and a steady mix of reef fish.
