Why dive here
With 168+ marine species recorded in the area - including barracuda, orcas, sea turtles, whale sharks and pufferfish - Great Wall offers some of Roatán's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
The Great Wall, over in Roatán’s Turtle Harbour, feels exactly as advertised. We love drifting along this sheer drop, where the reef gives way to a deep blue abyss. Roll off the boat, fin over, and just let yourself sink a little, watching the wall extend into the gloom below. We've pushed it down to 25 metres here, but the wall itself seems to go on forever, a proper geological feature rather than just a slope. It's a fantastic spot for spotting larger pelagics cruising by; we’ve had horse-eye jacks sweep past, and barracuda often hang out, just watching us. Look closer into the crevices, and you’ll find lionfish, although we always hope to see more of the native scorpionfish. The coral cap at the top of the wall is surprisingly healthy, teeming with smaller reef fish like yellowhead wrasse and bluestriped grunts. Visibility averages 23 metres, which gives you a great sense of that monumental drop-off. Our pick for an afternoon dive when the sun hits the wall just right, highlighting all the contours. It’s a site that really lets you appreciate the sheer scale of the ocean.
