Great Wall - Roatán

Les tunnels d’Actinéria sits tucked away on the outer reef, a nice escape from any choppy surface conditions. It’s a site that really comes alive if you slow down and actually look; those small faults and tunnels are absolutely packed with tiny details. We’ve spent whole dives just poking around, spotting electric flame scallops tucked into crevices, and more cowries than we knew what to do with – the lined-lip and carnelian are our favourites here. Sunlight filters in through the openings, highlighting the bright discus anemones and the orangutan crabs clinging to them. Deeper, around 17 metres, the brain and honeycomb corals form some impressive structures. While it’s certainly a spot for macro fans, we’ve also had surprising pelagic encounters. Once, we had a proper tiger shark cruise by, completely unexpected in such a sheltered spot. It just goes to show, you never quite know what will drift past. This spot is brilliant for photographers, especially those who love exploring small spaces and finding the hidden gems within a busy reef. You'll want good buoyancy for navigating the tighter sections.
