Big Rock
Utila sand-and-wall dive known for garden eels and seahorses.
About Big Rock
Big Rock is a popular Utila reef-and-wall dive built around a broad sandy slope that lets divers choose an easy shallower profile or continue deeper along the edge. It is best known for dense garden eel patches, sandy seahorse sightings, and a forgiving layout that makes it useful for both training-style dives and experienced teams who want longer time searching the slope.

Safety & Access At Big Rock
Hazards, restrictions, and access requirements.
Safety Notes
Big Rock is straightforward to route, but the depth range can change quickly if divers leave the shallower sand and follow the slope down. Keep training groups and newer divers on a clear depth cap and avoid turning seahorse hunting into a deeper-than-planned search.
