Little Caverns
A maze of coral canyons and swim-throughs where Caribbean reef sharks patrol and grouper shelter in shadowed passages.
Little Caverns offers some of Bimini's most dramatic underwater topography, a labyrinth of coral canyons and swim-throughs carved into the reef structure. The site ranges from 55 to 85 feet, with small tunnels opening into larger passages that allow divers to navigate through the reef rather than simply over it.
Caribbean reef sharks frequent the deeper sections, often appearing from the blue as divers emerge from the canyon passages. Large grouper station themselves at the tunnel exits, and schools of gray snapper swirl through the water column. The combination of structure and marine life makes Little Caverns a favorite among experienced Bimini divers.
Canyon and tunnel system
The reef at Little Caverns has eroded into a series of canyons running roughly perpendicular to the surface. Some passages are narrow slots requiring single-file passage, while others open wide enough for divers to swim side by side. The tunnels vary in length from brief swim-throughs to longer passages that wind through the coral.
Light penetrates most passages, eliminating the overhead environment concerns of true cave diving. The play of sunlight through the coral creates atmospheric conditions that photographers prize, especially during morning dives when the sun angle is favorable.
Marine life in the canyons
Caribbean reef sharks patrol the outer edges of the reef system, often visible as silhouettes beyond the canyon exits. Their presence adds excitement to every dive, though they typically maintain comfortable distances from divers. The sharks are resident, meaning sightings are common rather than exceptional.
Grouper of various species shelter in the tunnel openings, with Nassau grouper and black grouper both present. Schools of Bermuda chub and gray snapper gather in the open water, while the coral surfaces host the usual array of tropical reef fish.
Diving considerations
The depth range and swim-through passages suit intermediate divers with good buoyancy control. The site lies within easy boat range of North Bimini, typically combined with shallower sites for a multi-dive morning. Currents are generally mild, though flow through the canyons can occur.
Photographers should bring wide-angle lenses to capture the dramatic passages, while macro opportunities exist on the coral surfaces. The combination of topography and marine life provides variety for extended exploration.
Getting there
Little Caverns is reached by dive boat from North Bimini in approximately 15 to 20 minutes. The site is regularly visited by Bimini dive operators as part of standard reef diving rotations. Morning dives offer the best light conditions for photography in the canyon passages.
Frequently asked questions
- How difficult are the swim-throughs at Little Caverns?
- The passages vary from narrow slots to comfortable tunnels. Good buoyancy control is essential to avoid contact with coral. Divers should be comfortable in enclosed spaces, though all passages are open to natural light.
- Will I see sharks at Little Caverns?
- Caribbean reef sharks are regular visitors, often spotted beyond the canyon exits or cruising the reef edge. Sightings are common though never guaranteed. The sharks typically maintain distance from divers.
- Is Little Caverns suitable for photography?
- The dramatic topography suits wide-angle photography, with light through the canyons creating atmospheric conditions. Macro opportunities exist on coral surfaces. Morning dives provide optimal lighting angles.
