Coral fragments grow 2–4 times faster in nurseries than on the natural reef — restoration diving accelerates recovery that would otherwise take decades.
Under the surface off Green Turtle Cay, the reef should have been a graveyard. Instead, staghorn coral branches stretched toward the sun in thickets so dense they blocked the light. That difference is what a decade of active restoration looks like. The Perry Institute for Marine Science has planted over 15,000 corals across the Caribbean, and their long-term monitoring shows measurable increases in both coral cover and fish populations. This article walks you through how to join one of their Reef Rescue Expeditions — which options exist, what the actual diving involves, and how to prepare so you’re not figuring it out after you arrive.
You need PADI Open Water certification and comfort diving to 30–60 feet. The best entry point is the Green Turtle Cay expedition — capped at 8 divers, run by a family-owned dive center with its own coral nursery. It’s not cheap, but the ratio of instruction to hands-on restoration is higher than any other option.

The Reef Rescue Network — What You’re Actually Joining
The Perry Institute for Marine Science started the Reef Rescue Network (RRN) to connect dive shops, non-profits, and volunteers across the Bahamas, St. Lucia, Barbados, and Grenada. Today it runs 41 coral nurseries and involves locals and tourists in hands-on restoration. Each expedition includes the PADI Reef Rescue Diver specialty course, which covers coral biology, nursery maintenance, fragment handling, and outplanting protocols. You’re not just dropping coral fragments — you’re learning a replicable skill set.
What sets RRN apart from one-off volunteer days is the monitoring side. The institute has 15 years of post-planting data, so you get to see the long-term impact of the work. That matters when you’re spending a week underwater instead of a single afternoon.
Green Turtle Cay — The Most Hands-On Expedition
Green Turtle Cay is a three-by-half-mile island in the Abaco chain with a population around 550. The expedition base is the Bluff House Beach Resort & Marina, the oldest resort in the Out Islands, and the dive partner is Brendal’s Dive Center — a family-run operation that’s been running since 1985 and manages its own coral nursery. The expedition is capped at 8 divers, which means direct mentorship during every outplanting session.
The itinerary mixes restoration with recreational dives: you’ll outplant staghorn and elkhorn corals, explore the San Jacinto wreck (a Civil War–era steam frigate turned artificial reef), and snorkel the Wild Turtle Lagoon to observe green and hawksbill turtles. The Reef Rescue Diver certification is included, and the daily schedule adjusts based on weather and local conditions — a realistic concession to island diving.

Andros Island — Two Options at Different Price Points
Andros offers two expedition tracks through the same network. The Small Hope Bay Lodge expedition runs November 7–14, 2026, at $4,620 per person. It’s the all-inclusive option — meals and lodging are bundled into the price, which makes the upfront cost sting less if you’d otherwise spend heavily on food. The lodge is on the water, and the reef access is direct from the property.
The Forfar Field Station expeditions are cheaper ($2,850 for Spring 2027) but more rustic. Forfar is a research station, not a resort, so expect shared spaces and simpler meals. The trade-off is direct access to the marine science side of the work — researchers are often on-site, and the conversation runs deeper than at a standard resort. Winter 2027 (December 4–11) is also available, though water temperatures can drop to around 75°F, so a 3mm wetsuit helps.
What a Restoration Dive Actually Looks Like
Every expedition follows the same core arc — you arrive, train, dive, plant, and leave with a certification and a measurable contribution. Here’s how the week breaks down.
You need a current PADI Open Water certification (or equivalent) and comfort diving to 30–60 feet. Book through the Reef Rescue Network shop — deposits secure your spot, and the balance is due a few weeks before departure. If you’re not certified yet, factor in a PADI Open Water course before the expedition.
Day 1 is arrival and a welcome evening. You’ll meet the dive instructors, review the week’s schedule, and get fitted for any rental gear you need. The expedition leaders cover safety protocols, site conditions, and the specific restoration techniques you’ll use — no one is thrown into the water cold.
Over the first two days, you complete the PADI Reef Rescue Diver specialty course. This covers coral biology, the threats facing Caribbean reefs, nursery maintenance, and proper fragment handling. The certification is the backbone of the expedition — you earn it while doing the actual work, not in a classroom beforehand.
The core restoration days are split between two tasks: maintaining the nursery (cleaning, monitoring fragment growth, and recording data) and outplanting nursery-grown staghorn and elkhorn corals onto designated restoration sites. Instructors demonstrate each technique first, then coach you through it. Most dives are within 30–60 feet of the surface.
The schedule includes recreational dives to sites like Coral Caverns and the San Jacinto wreck, plus the Wild Turtle Lagoon snorkel. A lay day (usually day 7) lets you explore the island on your own before the farewell party and departure. The expedition ends with your PADI certification and the knowledge that the corals you planted are monitored for years afterward.
If you want to capture the outplanting process, a compact action camera with good stabilization works well underwater. The DJI Osmo Action 6 bundle includes a waterproof housing rated to 20 metres and a 58-piece accessory kit, so you can mount it on a tray or strap it to your wrist without worrying about leaks.
Certification, Costs, and What to Pack
The practical side of joining a Reef Rescue Expedition comes down to three things: meeting the certification requirement, understanding what the price includes, and bringing gear that won’t fail halfway through the week.
Certification requirements
You need a PADI Open Water Diver certification (or equivalent from another agency) and recent diving experience. The research dives are at 30–60 feet, so comfort at that depth matters more than advanced credentials. If you’re travelling with a certified diver who doesn’t have recent dives, most operators recommend a refresher course before the expedition — your local dive shop can arrange that.
What the price covers
The Green Turtle Cay expedition ($2,999–$4,099) includes accommodation at Bluff House, most meals, all diving, the Reef Rescue Diver certification, and the Wild Turtle Lagoon snorkel. It does not include flights to the Bahamas, transfers to Green Turtle Cay, or dive insurance. The Small Hope Bay Lodge expedition ($4,620) is all-inclusive — meals and lodging are bundled. The Forfar Field Station expedition ($2,850) is the cheapest but has more basic accommodation.
Gear worth bringing
Most expeditions provide tanks and weights, but you’ll want your own mask, fins, and a dive computer you trust. The Garmin Descent Mk3i doubles as a dive computer and a daily smartwatch, with air integration and diver-to-diver messaging — useful if you’re diving with a partner and visibility shifts. A 3mm wetsuit is sufficient for most of the year; December dives may call for 5mm.
If you’re flying into the Abacos, book a seat on the ferry from Treasure Cay to Green Turtle Cay ahead of time — the schedule shifts with the season, and the afternoon crossing often sells out.
Weather cancellations are real. The expedition itinerary adjusts daily based on wind and sea conditions, and a missed day of outplanting can’t always be rescheduled. Travel insurance with dive-specific coverage is worth the extra cost.
Before You Go: Coral Restoration Diving Questions Answered
Do I need to be an advanced diver?
No. The expeditions are designed for PADI Open Water divers (or equivalent) who are comfortable diving to 30–60 feet. You’ll be guided by instructors who demonstrate each technique before you try it. Advanced certifications help but aren’t required.
What happens if the weather is bad?
The daily itinerary is flexible — dive sites and outplanting sessions shift based on wind and sea conditions. If a full day of diving is lost, the expedition leaders adjust the schedule to prioritise certification dives over recreational ones. Travel insurance with weather-related cancellation coverage is recommended.
Can non-divers join the expedition?
The expedition is built around diving, so non-divers would miss the core activity. The Wild Turtle Lagoon snorkel is open to anyone, but the restoration work and Reef Rescue Diver certification are underwater. Some partners like Bluff House offer resort amenities for non-diving travel companions.
Is this suitable for teenagers?
PADI Junior Open Water certification starts at age 10, so teenagers who are certified and comfortable at depth can participate. The instruction style is hands-on and patient, which suits younger divers who learn by doing rather than sitting through lectures.
What’s the real environmental impact of one expedition?
Each participant directly outplants nursery-grown corals that are monitored for years afterward. The 15,000+ corals planted through the network have shown measurable increases in fish populations and coral cover at restoration sites. One week of diving won’t fix a reef, but the cumulative data from these expeditions informs restoration strategies across the Caribbean.
Diving With Purpose
Most dive trips end with a logbook full of sites and a fading tan. A Reef Rescue Expedition ends with a certification and the knowledge that a specific patch of reef is measurably healthier than it was a week ago. The cost is higher than a standard dive holiday, and the dates are fixed, but the ratio of meaningful work to recreational diving is hard to beat. If you’re already planning a Bahamas trip and want more from your bottom time than a photo of a turtle, this guide to Bahamas snorkeling and scuba diving sites pairs well with the restoration itinerary — same islands, deeper purpose.
