What you might see
- BarracudaLikely
Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.
Certification & difficulty
Advanced Open Water - advanced conditions (currents/depth); dive within your training.
Snorkelling
Not a snorkel site - no - too deep for snorkeling; scuba boat dive only
Safety notes
Depth (~30-37m) carries real risk of nitrogen narcosis and short no-decompression bottom times; interior/penetration diving adds overhead-environment hazards (silt-out, entanglement) and requires proper training, lights, reels, and redundant air per wreck-diving guides; occasional light current
Permits & fees
No fee - FKNMS mooring buoys are free and first-come, first-served sanctuary-wide; no specific wreck-diving permit/fee found
Permits and operators change - confirm before booking.
