Shallow artificial reef and underwater museum off Khao Lak.
Shallow artificial reef and underwater museum off Khao Lak.
Tor 13 is Khao Lak's artificial reef and underwater museum, reached by short boat trips and best treated as a shallow, beginner-friendly wreck-and-reef dive. The site combines a former navy vessel with trucks, concrete blocks, and other structures that are still building coral cover, creating a compact training-friendly area with plenty of fish life and classic macro sightings.
Site Conditions
Safety Notes
The site is shallow and beginner-friendly, but a cold current can arrive quickly, so keep an eye on the water and shorten the dive if conditions shift.
Access Restrictions
Short boat access from Khao Lak is the normal way in, and day-trip timing and sea state decide whether the site is on the program.
Legal Notes
This is an artificial reef and underwater museum, so follow the operator brief and any marine-area rules for the day trip.
Community notes to help plan your visit.
Scuba Diving
Best treated as a guided short boat trip with beginner-friendly reef exploration and enough structure for two easy dives.
Freediving
Freedive-style sessions are not the main focus; the shallow, controlled layout suits scuba training and relaxed snorkeling better.
Snorkeling
Snorkeling can work on calm days around the shallow structure, but the site is primarily set up for scuba.
