From the air, Great Inagua looks like a flat green disc floating in turquoise — and somewhere along its northwest coast, a tidal creek called Union Creek cuts into the mangroves. For more than fifty years, that narrow waterway has hosted one of the longest continuous sea-turtle research programs on the planet, a joint project of the Bahamas National Trust and the Archie Carr Center for Sea Turtle Research at the University of Florida. Getting there takes planning, a charter flight, and a bumpy ride from Matthew Town. But for anyone who wants to see endangered green and hawksbill turtles foraging in their natural habitat — and understand what real, quiet conservation looks like — Union Creek Reserve is a wetland worth every mile of the journey.
Green and hawksbill sea turtles have been studied continuously at Union Creek since 1974 — one of the longest-running datasets on these endangered species anywhere in the world.
Union Creek isn’t a casual day trip. You’ll need to book through the Bahamas National Trust, arrange a charter flight to Great Inagua, and brace for rough roads. But if your crew values wildlife observation over resort amenities, the payoff is extraordinary: seeing juvenile sea turtles in a protected mangrove nursery that scientists have monitored for half a century, all without a single crowd in sight.

Union Creek Reserve — A Living Laboratory for Sea Turtles
Union Creek Reserve sits inside the northwest corner of Inagua National Park, a saline lagoon with a narrow opening to the sea. Its sheltered waters, ringed by dense mangroves, create ideal foraging conditions for immature green turtles and hawksbill turtles — and that’s exactly why researchers have been coming here since 1974.
The Archie Carr Center for Sea Turtle Research at the University of Florida, in partnership with the Bahamas National Trust, has tagged, measured, and monitored turtles at Union Creek for over fifty years. The result is one of the longest continuous datasets on green and hawksbill populations anywhere, revealing crucial information about growth rates, habitat use, and migration patterns. Juvenile turtles spend years feeding in these protected seagrass beds before maturing and swimming off to distant nesting beaches. What scientists learn here has informed turtle protection efforts throughout the Caribbean basin.
For your family or crew, this isn’t a splashy turtle encounter where you swim alongside them — swimming with turtles is prohibited here, and human contact is strictly controlled to avoid disturbing ongoing research. What you get instead is something rarer: the chance to observe these animals behaving naturally in a pristine environment, with a guide who can explain the science behind the scene. If your group includes older kids or teens with an interest in marine biology, Union Creek offers a real-world look at how conservation research actually works.
The Mangrove Ecosystem — More Than Just Turtles
Union Creek’s mangroves do far more than shelter sea turtles. The dense stands of Avicennia germinans and Conocarpus erectus that line the creek filter the water, stabilize the shoreline, and create a safe nursery for juvenile fish, invertebrates, and resident bird species.
This is a genuinely productive ecosystem packed into a relatively small tidal lagoon. Beyond the turtles, you’ll find wading birds like tricolored herons, reddish egrets, and roseate spoonbills working the shallows. The mangrove roots host crabs, small shrimp, and the base of a food web that supports everything in the park. Because Union Creek is protected within the larger Inagua National Park — a Ramsar Wetland of International Importance (site no. 892) — the whole system remains undisturbed by development or industrial activity, even though salt production continues elsewhere on the island under strict zoning.
Ask your guide to pause at the creek’s edge before entering the lagoon. Early morning light filters through the mangroves at an angle that makes the water exceptionally clear — you’ll spot turtles and fish well before they spot you.
For travellers coming from busier islands, the quiet here is a feature, not a bug. There are no jet skis, no beach bars, no music drifting across the water. What you hear is the rustle of mangroves, the call of a passing heron, and the occasional splash of a turtle surfacing for air. If your family is used to constant stimulation, that stillness might take a moment to settle into — but it’s exactly what makes Union Creek different from any other wetland you’ll visit in The Bahamas.
Inagua National Park — Flamingos, Lake Rosa, and 151 Bird Species
Union Creek is one piece of a much larger protected area. Inagua National Park was established in 1965 and covers roughly 287 square miles — nearly the entire landmass of Great Inagua. Its centerpiece is Lake Rosa, a permanent shallow brackish lake up to 1.5 metres deep, dotted with small islands and fringed by saltmarshes and mangroves.
Lake Rosa is home to the world’s largest breeding colony of West Indian flamingos (Phoenicopterus ruber ruber). After decades of protection, the population has rebounded from about 21,000 birds in the early 1970s to an estimated 60,000 today. Seeing that many flamingos gathered in one place — a solid pink band stretching across a turquoise lake — is the kind of sight that rearranges your sense of scale. The park also protects the endangered Inagua Island turtle (Chrysemys malonei), endemic to Great Inagua, and the threatened Bahama parrot (Amazona leucocephala bahamensis).

Birders will want to budget extra time here. Over 151 species have been recorded in the park, including brown pelicans (around 200 breeding pairs), roseate spoonbills, white-cheeked pintails, and American crocodiles. The peak season for birding runs from November through April, when migratory species join the resident populations. If your crew includes someone who keeps a life list, Inagua will add entries they can’t get anywhere else in The Bahamas.
A separate protected area — Little Inagua National Park — covers the uninhabited island east of Great Inagua. It’s even more remote and accessible only by private boat with special permission. Most visitors focus on Great Inagua’s main park and Union Creek.
Visiting Union Creek — What the Logistics Actually Look Like
Union Creek is not the kind of place you decide to visit on a whim. Access requires coordination, advance booking, and a tolerance for rough travel. But the process is straightforward once you know the steps.
Before you book anything else, reach out to BNT Nassau to arrange an authorized guide for Union Creek. Independent visits are not permitted, and guides must be scheduled well ahead — especially during peak birding season (November–April). The same guide can typically combine a Union Creek visit with a flamingo tour of Lake Rosa. Check the official BNT Inagua page for current contact details.
The most reliable option is a charter flight from Nassau to Great Inagua Airport, which typically costs $1,200–$2,000 per person round-trip. Alternatively, weekly mail boats run from Nassau, but they’re infrequent and schedules change — not a great option if you’re on a fixed itinerary. Plan at least 6–8 months ahead if you’re traveling during peak months.
Matthew Town is the only settlement on Great Inagua. From there, the drive to Union Creek on the northwest coast follows rough roads and takes several hours round-trip. A sturdy vehicle is essential — your guide will handle this, but factor the travel time into your day. Morning departures give you calmer conditions and better visibility at the creek.
Once at Union Creek, you’ll observe turtles and other wildlife from a respectful distance. Swimming is prohibited, and you must maintain at least 50 metres from nesting birds and other protected species. Your guide will explain the research protocols and point out species you might otherwise miss. Plan for 1–2 hours on site, plus the round-trip drive.
Accommodation on Great Inagua is limited to a handful of guesthouses and small lodges in Matthew Town, running $80–$150 per night. Book well in advance — there are no hotels or resorts. Food and supplies should ideally be brought from Nassau, though basic items can be purchased locally at higher prices. A full-day guide runs $250–$400. All told, a four-day trip to Inagua — including flights, guide, lodging, and food — will likely cost $2,000–$3,500 per person.
Practical Considerations for Your Trip
The isolation that makes Inagua so remarkable also creates real logistical challenges. Here’s what to plan for before you go.
| Expense | Estimated Cost | Notes |
|---|---|---|
| Charter flight (round-trip from Nassau) | $1,200–$2,000/person | No regular commercial flights |
| Local guide (full day) | $250–$400 | Must be arranged through BNT |
| Accommodation (per night) | $80–$150 | Limited guesthouses in Matthew Town |
| Food & supplies | Variable | Bring from Nassau to save cost |
| Total 4-day trip (per person) | $2,000–$3,500 | Excludes binoculars, field clothing, water filters |
Health, Safety, and Rules
Medical facilities on Great Inagua are limited to a small clinic in Matthew Town. For anything serious, evacuation requires an air ambulance. Travel insurance with remote-area coverage is essential, not optional. Weather can shift quickly, particularly during hurricane season (June–November), and trip cancellations due to weather or transport delays are a real risk.
No drones without prior approval from the Bahamas National Trust — flying one over the flamingo colony or Union Creek without permission violates park regulations and can disturb nesting birds. Also, don’t approach wildlife within 50 metres, and pack out all waste. Rules are strictly enforced here, and for good reason.
What to Pack
Binoculars are the single most useful item you can bring — for turtle observation, birding, and flamingo viewing. Field clothing that covers your arms and legs will help against sun and insects. A water filter or purification tablets are wise, since potable water can be inconsistent. And because there’s no reliable internet or ATM on the island, bring enough cash for your entire stay and download maps and communications tools before you leave Nassau.
- Union Creek requires an authorized guide arranged through the Bahamas National Trust — independent visits are not permitted and may violate park regulations.
- Getting to Great Inagua means a charter flight or infrequent mail boat; plan 6–8 months ahead and budget $2,000–$3,500 per person for a 4-day trip.
- Swimming with turtles is prohibited, but guided observation from a respectful distance offers a rare window into one of the world’s longest-running sea turtle research programs.
- Combine your Union Creek visit with the flamingo colony on Lake Rosa — together they make the long journey genuinely unforgettable.
Before You Go — Great Inagua
How do I actually book a visit to Union Creek?
Contact the Bahamas National Trust in Nassau directly to arrange an authorized guide. They’ll coordinate the date, confirm access, and can often pair your visit with a flamingo tour of Lake Rosa. Do this before booking flights or accommodation.
Don’t rely on third-party operators claiming to offer Inagua tours — verify credentials with BNT. Unauthorized guides may operate illegally and can disrupt nesting colonies.
What’s the biggest downside to visiting Inagua?
The access difficulty is real. No regular flights, limited medical care, basic accommodation, and the risk of weather cancellations. If your crew needs reliable internet, restaurant variety, or resort amenities, Inagua will frustrate you.
That same isolation is exactly what makes the wildlife experience so powerful — but it’s a trade-off you need to go into with eyes open.
When is the best time to go?
November through April offers peak birding season, cooler temperatures, and lower hurricane risk. Morning visits to Union Creek provide calmer water and better visibility for turtle observation.
Sea turtles can be seen year-round at Union Creek since it’s a foraging habitat, not a nesting beach — so timing isn’t critical for the turtles themselves.
Can kids visit Union Creek?
Yes, but it depends on the kids. The rough drive, strict protocols, and lack of swimming interaction mean younger children may struggle. Older kids and teens with an interest in wildlife or marine science will find it genuinely fascinating.
For families with younger children, the flamingo colony at Lake Rosa offers more immediate visual payoff with less patience required.
What happens if the charter flight is cancelled?
Weather delays are common, especially June–November. Build buffer days into your itinerary — at least one or two — and carry travel insurance that covers trip cancellation and medical evacuation.
There are no same-day alternatives. If your flight is cancelled, you wait for the next one.
The Wetland That Rewards the Journey
Union Creek Reserve isn’t trying to be convenient. It’s a working research site in one of the most remote corners of The Bahamas, and every part of the visit — the planning, the flight, the rough road, the quiet — reflects that reality. But standing at the edge of that tidal lagoon, watching a green turtle surface in water clear enough to see its every movement, while a scientist explains what fifty years of data have revealed about that very animal’s migration route, is the kind of experience that changes how you think about travel. It’s not about ticking off a destination. It’s about understanding why some places are worth protecting in the first place.
