Allan's Cay Anchorage

Anchorage and Holding

The Allan's Cay lagoon offers excellent protection from all directions when conditions allow entry. Anchorages lie between Leaf Cay and Allen Cay, as well as inside the arms of Southwest Allan's Cay. Holding is fair to good in sandy patches throughout the lagoon.

Strong reversing tidal currents sweep through the anchorage, making a two-anchor Bahamian moor advisable to prevent excessive swinging. This technique keeps your vessel aligned with the current rather than the wind, reducing the strain on ground tackle and preventing swing into neighboring boats.

The Rock Iguanas

The Allan's Cay Rock Iguana (Cyclura cychlura inornata) exists only on these few tiny cays. After centuries of hunting nearly drove them to extinction, legal protection under Bahamian and international law has enabled a remarkable recovery.

With no natural predators and protection from human harvest, the iguanas have become entirely unafraid of visitors. They will pose for photographs with hardly a blink, approaching the beach when boats arrive. While they will accept food, wildlife experts recommend against feeding them to preserve natural behaviors.

Access and Exploration

Southwest Allen's Cay features a sandy beach providing easy dinghy landing and access to the iguana habitat. The iguanas roam freely among the sea grapes and mangroves along the beach.

In settled weather, the anchorage sees considerable traffic as boats arrive to observe the wildlife. During frontal passages, the protected lagoon fills with vessels seeking shelter. The nearby Highborne Cay provides marina services for those needing fuel, provisions, or a protected slip.

Approach and Entry

Allan's Cay lies approximately 40 nautical miles southeast of Nassau, making it the traditional first landfall for vessels heading into the Exumas. The lagoon formed by Allan's Cay, Southwest Allen's Cay, and Leaf Cay creates a natural harbour accessed from the banks side. Approach from the west, reading the water carefully as shallow patches flank the main channel on both sides.

The anchorage features a deeper pocket of 15 to 20 feet in the center of the lagoon, though much of the surrounding area runs considerably shallower at 6 to 10 feet. First-time visitors should favor the deeper blue water visible through the remarkable clarity, avoiding the lighter turquoise patches that indicate shoaling. A late morning or early afternoon arrival with good overhead light makes visual piloting straightforward. Note: This information is for planning purposes; always consult official charts and current cruising guides before approaching.

Anchoring Technique and Current

Strong reversing tidal currents sweep through the Allan's Cay lagoon, requiring the classic Bahamian moor technique. Set your primary anchor up-current, motor back while paying out double your intended scope, then drop a second anchor 180 degrees opposite. Fall back to the midpoint and snug both rodes to keep your vessel aligned with the current rather than the wind.

This technique prevents the dramatic swinging that occurs in single-anchor situations here and eliminates the risk of collision with neighboring boats during tidal changes. The sandy bottom provides good holding once anchors are well set, though the deeper pocket accommodates only a handful of vessels. During peak season or when weather drives boats to shelter, the prime spots fill early. Arriving by mid-morning improves your chances of securing the best holding ground.

What to Do Here

The primary draw at Allan's Cay is wildlife. Southwest Allen's Cay and Leaf Cay host colonies of the endemic Allan's Cay Rock Iguana, found nowhere else on Earth. These prehistoric-looking reptiles have grown accustomed to visitors over decades and will approach the beach as dinghies arrive. They possess poor eyesight and may mistake fingers or toes for food, so keep hands visible and feet in shoes when feeding.

Beyond the iguanas, excellent snorkeling awaits throughout the lagoon. Coral heads scattered across the sandy bottom harbor reef fish, while the crystal-clear water makes underwater exploration rewarding even with basic gear. Conch harvesting (in season and following Bahamian regulations) provides fresh provisions for cruisers willing to free-dive. The pristine beaches invite kayaking, paddleboarding, and simply wandering the shoreline collecting shells.

Practical Considerations

Allan's Cay has no facilities whatsoever. There is no fuel, water, power, provisions, or cellular service. Cruisers must arrive completely self-sufficient with full tanks, topped-up water, and adequate provisions for their intended stay. Highborne Cay Marina lies just a few miles south and offers fuel, water, a small store, and VHF monitoring on channel 16.

The anchorage serves both as a popular first-night stop from Nassau and as a refuge during frontal passages when vessels seek the lagoon's all-around protection. During unsettled weather, expect company. When conditions are fair, you may have this remarkable spot largely to yourself. Plan water activities during high tide for maximum paddling range and access to small inlets and hidden beaches around the cays.

Getting there

Allan's Cay lies at the northern end of the Exumas chain, approximately 40 nautical miles southeast of Nassau and just north of Highborne Cay. The anchorage is accessible from the banks side with attention to the cays forming the lagoon entrance. Strong currents require careful approach. The cays have no facilities; provisioning and fuel are available at Highborne Cay to the south or by returning to Nassau.

Frequently asked questions

Can I land on the beach to see the iguanas?

Yes. Southwest Allen's Cay has a sandy beach suitable for dinghy landing. The iguanas are accustomed to visitors and will often approach. Handle them gently if at all, and wildlife experts recommend against feeding to preserve natural behaviors.

Why is a Bahamian moor recommended here?

Strong reversing tidal currents flow through the lagoon, causing boats at anchor to swing dramatically. A Bahamian moor with two anchors keeps your vessel aligned with the current, reducing strain on tackle and preventing collision with neighboring boats.

Are the iguanas dangerous?

No. The Allan's Cay Rock Iguanas are docile and accustomed to humans. They pose no threat to visitors, though as with any wildlife, respectful distance is appropriate. They may approach expecting food but are not aggressive.

How deep is the main anchorage at Allan's Cay?

The lagoon features a central pocket of 15 to 20 feet, though surrounding areas are considerably shallower at 6 to 10 feet. Arriving with good overhead light allows visual identification of the deeper water. Boats have touched bottom during low tide when anchored in marginal depths, so favor the deeper zones.

What supplies can I get at Allan's Cay?

None. Allan's Cay is uninhabited with no facilities, fuel, water, provisions, or services. Arrive fully provisioned and self-sufficient. Highborne Cay Marina a few miles south offers fuel, water, and basic supplies. Nassau to the northwest provides full provisioning before beginning the Exumas cruise.

Is the Bahamian moor difficult to set up?

The technique requires practice but becomes straightforward once learned. Drop your primary anchor up-current, pay out double your intended scope while motoring down-current, drop the second anchor, then fall back to center and adjust both rodes. The payoff is a stable boat that tracks with the current rather than swinging wildly.
