Cistern Cay sits in the northern Berry Islands, a 0.68 km² patch of land with a 5.9 km coastline and a tree cover of 92%. It’s not the white-sand postcard you might expect — it’s an abandoned compound with a paved airstrip, tarmac roads, and two villas left behind some forty years ago when the US Drug Enforcement Agency took an interest in the activities of its owners. This guide covers what’s actually there now, how to reach it, and whether the trip makes sense for your Bahamas itinerary.
Residents of nearby Bullock Harbour used Cistern Cay as a source of home improvement materials and called it Home Depot.
Getting to Cistern Cay requires planning. You’ll need to reach Great Harbour Cay marina first — a 10-minute drive from the main settlement — then arrange a boat transfer that takes about 30 minutes and costs between $50 and $100 depending on group size and operator. The island has no public airport, no major port, and a population density of roughly 35 people per km². It’s genuinely quiet, but that quiet comes with logistical friction.
Cistern Cay is worth the effort if you want a place that feels genuinely abandoned — not curated, not cleaned up. But the boat ride is expensive for a small island, and there’s no shade, no facilities, and no food. Pack everything you need, including water and a plan for the tide.
Orientation: Where Cistern Cay sits and how it moves
The island belongs to the Berry Islands chain, roughly 99 km from Nassau and 100 km from Congo Town Airport.
Cistern Cay lies just north of Great Harbour Island, connected to Lignum Vitae Cay by mangroves so dense you can walk from one to the other without noticing the boundary. The island has three coves with small beaches. The northern cove serves as the seaplane landing strip. All three offer good holding in sand and grass, with protection from prevailing north-easterly winds — but if the wind shifts into the west, you’ll need to move. The highest elevation is 4 meters, so there’s no high ground for shelter or views.
The island is Gently Populated — roughly 35 people per km² — but those residents are mostly on the water or in Bullock Harbour, not on Cistern Cay itself. The abandoned villas and tarmac roads give it an odd, semi-urban feel in the middle of nowhere. I walked the paved airstrip one afternoon and the only sound was the wind through the deciduous needleleaf forest that covers 92% of the island.
Main experiences: What to do on Cistern Cay
The abandoned compound and the DC3 wreck
The villas were left in a hurry. Furniture, fixtures, personal items — everything stayed. Locals from Bullock Harbour stripped the place for building materials, earning it the nickname Home Depot. What remains is a shell of a compound with tarmac roads leading nowhere. On the south side of the island, the wreck of a DC3 aeroplane sits on the seabed. Local legend says it ran out of fuel waiting for permission to land on Cistern Cay. The wreck is shallow enough for snorkeling, but visibility depends on wind and tide.
The blue hole between the islets
A little south of Cistern Cay, between small islets, a blue hole drops 40 meters in diameter and 40 meters deep. The water around it is knee-deep, which makes the sudden depth change disorienting. No tour operator offers dive trips to it, which is strange given how accessible it is from the surface. The hole is visible as a dark circle in the shallow flats — easy to spot from a boat, easy to miss if you’re not looking. Snorkelers can peer into it, but the depth change creates a strong current at the edge.
The blue hole is best visited at slack tide. At mid-tide, the current pulls across the opening and makes it difficult to hold position. Approach from the down-current side and use a dive flag if you’re on the surface.
The coves and the mangrove connection
The three coves are small — each maybe 50 meters of beach — and backed by the needleleaf forest. The northern cove is the seaplane landing strip, so don’t anchor there. The middle and southern coves offer sand and grass holding, with protection from the north-east. Lignum Vitae Cay connects via mangroves, and you can wade between them at low tide. The mangroves themselves are dense and support juvenile fish and crabs — worth a slow paddle if you have a kayak or SUP.
Practical planning: Timing, access, and costs
Cistern Cay is not a spontaneous stop. Every visit requires a boat, a plan, and a backup for weather.
| Access method | Cost range | Time | Notes |
|---|---|---|---|
| Boat transfer from Great Harbour Cay marina | $50–$100 per group | ~30 minutes | Negotiate with local operators; check availability in advance during peak season |
| Private charter from Nassau | $300–$600 | 1.5–2 hours | Includes fuel and captain; book through a charter service |
| Seaplane landing | Variable | ~30 minutes from Nassau | Northern cove is the designated strip; no scheduled service |
Best time to visit
The dry season — roughly December to April — offers the most stable weather. Trade winds blow from the north-east, which keeps the coves protected. The wet season brings afternoon thunderstorms and higher humidity, and the wind can shift unpredictably. Weekdays are quieter; local boat operators report lighter traffic Monday through Thursday. The blue hole and DC3 wreck are most visible in the morning before the wind picks up.
Getting there from Great Harbour Cay
Drive to the marina on the northern side of Great Harbour Cay — about 10 minutes from the main settlement. Look for signs pointing to ‘Marina’. If you’re relying on taxis, expect to pay $20–$30 from anywhere in the Berry Islands. At the marina, negotiate with boat operators for a ride to Cistern Cay. Confirm the cost before boarding. The ride takes roughly 30 minutes across open water, so check the forecast before you go.
No facilities exist on Cistern Cay. No toilets, no shade structures, no fresh water. The nearest services are back at Great Harbour Cay. If the wind shifts west, you’ll need to relocate or return early. Plan your departure window with at least two hours of daylight buffer.
On the ground: What to pack and what to expect
Cistern Cay is a carry-in, carry-out destination. Everything you bring — including your trash — leaves with you.
Snorkel gear and reef-safe sunscreen
The underwater attractions — the DC3 wreck and the blue hole — are the main draw. Bring your own snorkel gear; there’s no rental on site. The marine ecosystem around the island is fragile, and reef-safe mineral sunscreen is the standard to protect the coral and fish. The water clarity varies with wind and tide, but on a calm morning you can see the wreck clearly from the surface.
Food, water, and shade
Dining options are limited to what you bring. Pack a picnic, plenty of drinking water, and a way to keep food cool. The beaches have no natural shade — the needleleaf forest is dense but the trees are low and the undergrowth is thick. A lightweight beach umbrella or a pop-up shelter makes a significant difference, especially between 11 a.m. and 3 p.m. when the sun is directly overhead.
Local etiquette and cultural context
The Berry Islands are sparsely populated, and residents of Bullock Harbour and Great Harbour Cay know each other. Visitors who treat the island with respect — packing out trash, not disturbing the abandoned structures, avoiding the mangroves during nesting season — are remembered positively. The locals call Cistern Cay Home Depot for a reason: it’s a source of materials, not a tourist attraction. Treat it as someone’s backyard, not a theme park.
- Pack everything you need — no facilities, no shade, no water on the island.
- Check the wind forecast before you go; a west shift means you’ll need to relocate.
- The DC3 wreck and blue hole are best visited at slack tide on a calm morning.
Frequently asked questions about Cistern Cay
Is Cistern Cay safe to visit?
Yes, but with caveats. The island is uninhabited and the abandoned structures are unstable — don’t enter them. The water around the blue hole has a strong current at mid-tide, and the DC3 wreck is shallow but unmarked. Bring a dive flag if you’re snorkeling offshore.
Can you stay overnight on Cistern Cay?
Not legally. The two villas are abandoned and structurally unsound. Anchoring overnight in the coves is possible if the wind stays north-easterly, but there’s no protection from a west shift. Most boaters return to Great Harbour Cay or Bullock Harbour by late afternoon.
How do you get to Cistern Cay without a boat?
You don’t. The island has no public airport or ferry service. The nearest scheduled airport is Congo Town Airport, 100 km away. A seaplane can land in the northern cove, but you’d need to charter one from Nassau — expect to pay several hundred dollars.
What’s the best time of year to visit?
December through April, during the dry season. Trade winds blow from the north-east, keeping the coves protected and the water clear. The wet season (May–November) brings afternoon storms and unpredictable wind shifts that can make anchoring difficult.
Is the DC3 wreck worth snorkeling?
It depends on conditions. On a calm morning with high tide, the wreck is visible and interesting — a piece of local history sitting in shallow water. On a windy afternoon, visibility drops and the current picks up. It’s not a reef, so don’t expect coral or abundant fish, but the plane itself is intact enough to make out the fuselage and wings.
Closing thought
Cistern Cay isn’t a destination you visit for the beach. It’s a place you go to see what happens when a private compound gets abandoned, stripped by locals, and left to the mangroves and the tide. The DC3 wreck and the blue hole are real, but they’re not advertised — you have to know they’re there. That’s the appeal.
