Use a local boat operator to line up the tide window and far-islands schedule.
Sail Rock, Ko Batong is a submerged ridge on the Tarutao National Marine Park far-islands run, off the back of Koh Dong. The site mixes hard-coral ledges, soft coral patches, and sandy pockets that pull in schooling fish, batfish, stingrays, and occasional turtles. Plan it as a boat dive with a local operator, because the same ridge can feel easy on a mild tide and much more demanding when the current picks up.

Key Hazards
Safety Notes
Watch the tidal window closely. The site is best treated as a relaxed coral ridge on mild days and a stronger drift when the current builds.
Access Restrictions
Boat-only access; plan around the Tarutao National Marine Park season and tide windows. Far-islands runs may be limited outside the November-April service period.
Legal Notes
Inside Tarutao National Marine Park; follow park rules and seasonal access windows.
