Tilloo Cay

Tilloo Cay National Reserve

Established in 1990 as a gift to the Bahamas National Trust, the Tilloo Cay National Reserve encompasses 11 acres of wild Atlantic shoreline. The oceanfront features eroded coral rock ledges and low-growing silver buttonwood scrub that has been "kept natural forever" per the original conservation agreement.

The reserve is internationally recognized as an Important Bird Area, providing critical nesting habitat for white-tailed tropicbirds from March through October. Yellow-crowned night herons and several tern species also breed here. With minimal infrastructure and no permanent staff, the reserve remains a true wilderness—visitors should tread lightly and observe wildlife from a respectful distance.

Tilloo Bank and Tilloo Cut

The shallow Tilloo Bank west of the cay is a highlight for anyone exploring by dinghy, kayak, or paddleboard. The water clarity is exceptional, revealing a sandy bottom dotted with large cushion starfish, sea biscuits, and sand dollars. Snorkelers may also spot loggerhead turtles and southern stingrays gliding through the shallows.

Tilloo Cut, the narrow strait between the cay and Tahiti Beach, provides a relatively safe passage between the protected Sea of Abaco and the open Atlantic. Though deeper and more forgiving than many Bahamian cuts, it can develop rough conditions when northeast winds oppose the tide—local knowledge and careful timing remain essential.

Anchorages and Access

Cruising vessels typically anchor in the lee of Tilloo Cay, north of Tilloo Bank. This open roadstead offers good holding in sand but is exposed to westerly winds, making it best suited for settled weather or short daytime stops. The nearby Tilloo Pond, a small protected basin, provides better shelter when conditions deteriorate.

From the anchorage, dinghy trips to Tilloo Bank, the nature reserve shoreline, and neighboring Lubbers Quarters are all within easy reach. The cay has a handful of private homes but no public docks, shops, or services—self-sufficiency is key for visitors.

Reading the Approach

Approaching Tilloo Cay from the Sea of Abaco requires attention to the shifting shallows that extend west from the cay. The deep blue water fades to brilliant turquoise over Tilloo Bank, where depths drop to just waist-deep at high tide. In settled conditions, you can work your way close to the bank for spectacular wading and snorkeling, but keep a sharp eye on your depth sounder and be prepared to back off if the bottom rises faster than expected.

The anchorage in the lee of Tilloo Cay offers good sand holding in six to twelve feet of water, though the roadstead is open to westerly winds. Prudent skippers treat this as a day anchorage in anything but settled easterlies. For more protection when weather threatens, consider relocating to White Sound on Elbow Cay or continuing south toward Lynyard Cay.

Tilloo Pond and Weather Holes

Tilloo Pond, a small enclosed basin on the northern end of the cay, has historically offered refuge in deteriorating weather. However, cruisers report mixed experiences with holding in the grassy bottom, and the entrance can be challenging for boats drawing more than four feet. If your anchor refuses to set in the grass, try relocating to the sandy patches along the southern edge of the pond.

Strong tidal currents flow through the area, particularly near Tilloo Cut. Swimmers and snorkelers should be aware that these currents can sweep you from shallow wading areas into deeper water surprisingly quickly. Always swim with a buddy and keep your dinghy nearby when exploring the banks.

Wildlife and Conservation

The eleven-acre Tilloo Cay National Reserve protects some of the most important nesting habitat for white-tailed tropicbirds in the Bahamas. These elegant seabirds, with their distinctive long tail streamers and yellow or orange bills, breed from March through June and remain in the area through October. Their courtship flights involve dramatic aerial displays where males droop their tails while circling potential mates.

Yellow-crowned night herons and several tern species also nest along the wild Atlantic shoreline, where eroded coral rock ledges and low-growing silver buttonwood provide shelter. The reserve has no trails, staff, or infrastructure by design. Visitors should observe wildlife from the water or shoreline without disturbing nesting areas, particularly during breeding season.

Snorkeling Tilloo Bank

Tilloo Bank offers a unique snorkeling experience quite different from reef diving. The crystal-clear shallows reveal a sandy bottom dotted with large cushion starfish in vibrant orange and red, sea biscuits, and sand dollars half-buried in the sediment. Southern stingrays glide through these waters, often allowing close approach if you move slowly and avoid sudden movements.

Loggerhead turtles cruise the bank, grazing on sea grass and surfacing for air. The best visibility typically occurs on calm mornings before afternoon winds chop the surface. Bring water shoes or fins for walking the bank, as sharp shell fragments occasionally punctuate the sand. The bank extends for nearly a mile, providing ample space to explore without crowding other snorkelers.

Getting there

Tilloo Cay is accessible only by private boat. Charter guests typically sail south from Marsh Harbour or Hope Town, anchoring in the lee of the cay for day visits or overnight stays in calm conditions. The Tilloo Bank and nature reserve are best explored by dinghy, kayak, or paddleboard launched from your anchored vessel. There is no ferry service or public dock on the cay.

Frequently asked questions

Can you visit the Tilloo Cay National Reserve?

Yes, the reserve is open to visitors, though it has no trails, facilities, or staff. The shoreline can be explored by dinghy or kayak. Visitors should avoid disturbing nesting tropicbirds, especially from March through October.

Is Tilloo Cut safe for passage?

Tilloo Cut is considered one of the safer ocean passages in the Abacos, with adequate depth for most cruising vessels. However, conditions can become rough when northeast to east winds oppose the tidal flow, so timing and local knowledge are important.

What marine life can you see at Tilloo Bank?

The shallow, crystal-clear waters of Tilloo Bank are home to large cushion starfish, sand dollars, sea biscuits, southern stingrays, and occasional loggerhead turtles. The area is ideal for wading, snorkeling, and paddleboarding.

Is it safe to transit Tilloo Cut?

Tilloo Cut is considered one of the safer Atlantic passages in the Abacos, with adequate depth for most cruising vessels. However, conditions can turn rough quickly when northeast to east winds oppose the outgoing tide. Time your transit for slack water or a flooding tide with light winds for the most comfortable passage.

Can you land on Tilloo Cay?

The cay is privately owned with a handful of vacation homes, and the national reserve portion has no landing facilities. Most visitors experience Tilloo from the water by anchoring in the lee, snorkeling Tilloo Bank, or exploring the shoreline by dinghy. Respect private property and avoid disturbing wildlife in the reserve area.

What is the best time of year to see tropicbirds at Tilloo Cay?

White-tailed tropicbirds breed at Tilloo Cay from March through June, with birds remaining in the area through October. April and May typically offer the best viewing opportunities as birds are actively courting and nesting along the Atlantic shoreline.
