The woolly mammoths of the ocean
Our most beloved conservation partners are going back — and this time you get your hands in the water with them.
Tela is the reef that should not exist.
Reefs across the Caribbean have bleached, broken and gone quiet. This one sits at roughly 70% live coral cover, against a regional average nearer 18%, and nobody fully understands why. That is not a marketing line. It is an open scientific question, and we get to swim around inside it.
Then there is the elkhorn. Twenty years ago elkhorn was the most abundant coral on Caribbean shores. Today there are 13 wild elkhorns left in all 300 miles of Florida’s reef. THIRTEEN. In Tela there are tens of thousands of colonies, in dense jungles stretching at least four kilometres — thought to be the largest wild population left anywhere in the Caribbean. Juli calls them the white rhinos of the ocean. Swimming through them is like swimming in a herd of woolly mammoths.
We are going back with the two people who know this water best. Dr. Juli Berwald literally wrote the book on coral reefs, and she co-founded Tela Coral to protect this one. Antal Börcsök is the man who heard locals talk about rocas offshore, went to look, and found that the rocks were alive.
And then it stops being a dive trip. If conditions allow, you will take part in an actual elkhorn translocation — real citizen science, not a photo opportunity. You will be shown how to handle “fragments of opportunity”, the pieces snapped off by waves and illegal anchor drops, and you will hold coral in your hands. It counts toward a live scientific study, and it builds new habitat for the quarter of all marine life that depends on reefs.
Six nights. Four in a treehouse above the ocean, two in the mangroves of Jeanette Kawas National Park. Ten of us, no more. And $500 of what you pay goes straight to Tela Coral.
This is the one we are proudest of.

You do not need a certification to come on this retreat. Non-divers can take part in a discovery dive without any prior qualification, and you can snorkel the reef — which, on a reef this shallow and this alive, is not the consolation prize it usually is. The elkhorn grows near the surface.
If you would like to get certified, you can do it right here in Tela with Antal’s team: $500 plus your accommodation and food costs for the extra days. Tell us when you book and we’ll set it up.
Everything on this retreat was chosen on purpose. These three are the heart of it.
If conditions allow, we join a translocation of elkhorn coral — part of a live experiment to understand how these rare corals respond to their environment, and to build new reef habitat. You will be shown how to handle elkhorn “fragments of opportunity”: pieces broken off by waves or by illegal anchor drops. It is a rare chance to actually hold coral, and it counts toward a real scientific study.
Twenty years ago elkhorn was the most abundant coral on Caribbean shores. Today only 13 wild elkhorns remain across all 300 miles of Florida reef. Tela is estimated to hold tens of thousands of colonies, in dense jungles stretching at least four kilometres — thought to be the largest wild population left anywhere in the Caribbean. Juli calls it the white rhino of the ocean. Swimming through it is like swimming in a herd of woolly mammoths.
This reef should be dead. Decades of pollution, heat and disease have flattened reefs across the Caribbean, and this one sits at roughly 70% live coral cover against a regional average nearer 18%. Nobody fully knows why. You dive it with Antal, who found it, and Juli, who studies it — and your trip includes a $500 donation straight to Tela Coral’s conservation work.
The translocation dive is weather and conditions dependent. It is a genuine scientific activity, not a scheduled attraction, and it only happens when it is safe and appropriate for the corals. We will always tell you honestly on the day. Everything else on this retreat runs regardless.
A night dive on the reef, a tour of the TelaMarine Aquarium, a scientific presentation from Juli and Antal, and a day out to Punta Sal Island. See the Inclusions tab for everything.
A $750 deposit secures your spot. A second payment of $1,275 is due November 30, 2026, and your remaining balance is due February 28, 2027. After submitting your deposit, you’ll receive a confirmation email with options to select your preferred payment plan.
This retreat splits in two, on purpose. Four nights in a treehouse above the ocean — built up into the mango trees, with a pool and views out over the water. Then two nights in the mangroves of Jeanette Kawas National Park, on the water, where the herons stand on the dock in the morning and the mountains sit blue across the lagoon.
They could not be more different, and that is the point. Ten of us, no more, in both.
Four nights in the treehouse property — decks, a pool, and the ocean through the mango canopy.
Two nights in the mangroves inside a national park. Quiet in a way that is difficult to describe.
Small enough that the dive boat is ours and everybody actually knows each other by day two.

Your Dive Host
Founder, Tela Marine | Co-manager, Marine Protected Area
Antal is Honduras-born, Hungarian by family, and the reason anybody dives Tela at all. Locals talked about rocas offshore — rocks. Newly certified, he and Alejandra went to look, and the rocks turned out to be very much alive. He spent the next few years getting coral scientists to come and see what was in his front yard.
He founded Tela Marine — the dive shop, the aquarium and the education centre — and co-manages the Marine Protected Area. His PADI instructors take small groups out to Mushroom Mound, Canyon and Rotunda. Nobody knows this water better.
