Independent Koh Tao wreck write-up confirming the site identity and general recreational access.
Koh Tao's signature wreck dive with sheltering fish and a guide-led route.
Koh Tao's signature wreck dive with sheltering fish and a guide-led route.
Boat access and wreck guidance make a local operator the practical way to dive it.
HTMS Sattakut is Koh Tao's signature wreck dive: a deliberately sunk former navy ship turned artificial reef just off the island's west side. Divers work around the hull, deck guns, and superstructure on a guide-led boat dive, with fish sheltering in the structure and a route that rewards relaxed buoyancy and comfort with deeper recreational profiles.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
18m - 35m

Year-round, with calmer sea days usually offering the easiest rides and the cleanest plan.
Typical Conditions
Guide-led wreck profile with variable visibility, some current sensitivity, and overhead sections inside the ship.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Stay within wreck-training limits and keep close control of buoyancy if you move inside the structure.
Access Restrictions
Boat-only from Koh Tao; not a shore-entry site.
Legal Notes
Follow guide instructions and any wreck-penetration or local site rules in force that day.
Community notes to help plan your visit.
Scuba Diving
A good fit for wreck-minded scuba divers who are comfortable staying calm and precise around the hull.
Freediving
Not a primary freedive target; the wreck is too deep and overhead-heavy for casual breath-hold dives.
Snorkeling
Not a snorkel-first site; the main structure sits below the surface.
