Safety Notes
Keep trim close to the reef edge and the boulder sections. The site is easy overall, but the hard-coral structure still rewards conservative finning and buoyancy.
Community notes to help plan your visit.
Scuba Diving
Best as a relaxed boat dive with slow reef-edge passes, wreck sections, and time to look for small life along the structure.
Freediving
Possible only on the shallower edge in calm conditions, but the site is primarily set up for scuba rather than freediving.
Snorkeling
Shallow sections may suit calm-water snorkelling, but the most interesting structure sits deeper and is better appreciated on scuba.
