Koh Rok
Marine-park reef trip with clear water and coral gardens.
Speedboat access from Koh Lanta to shallow coral gardens, good visibility, and easy-profile marine-park diving that also suits snorkelers.
About Koh Rok
Koh Rok is a marine-park island pair with shallow coral gardens, clear water, and an easy boat-access profile from Koh Lanta. The reefs are broad and gently sloping rather than dramatic drop-offs, which makes the area a strong fit for relaxed diving, snorkeling, and beginner-friendly trips in settled weather. Expect vibrant hard and soft coral, good surface-friendly structure, and a steady mix of turtles, snapper, moray eels, surgeonfish, and other reef fish. Planning is mostly about choosing a calm day, timing the speedboat transfer, and using the shallow reefs for an easy scenic marine-park outing.
