Why dive here
With 168+ marine species recorded in the area - including barracuda, orcas, sea turtles, whale sharks and pufferfish - Half Moon Wall offers some of Roatán's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
Half Moon Wall, just off West End, is one of those Roatán sites we always find ourselves coming back to. It’s an easy run for most boats, making it popular, but don’t let that fool you into thinking it’s just another wall. The reef crest starts shallow, around 5m, before dropping away to our max depth of 22m. What we love here is the sheer density of life clinging to the wall itself. You’ll spot parrotfish everywhere, munching away, and the occasional great barracuda hanging in the blue. Keep an eye out for the smaller stuff too: we’ve spent ages watching rusty gobies darting in and out of crevices and the shy rosy blennies peeking from their holes. The black coral formations are particularly striking, contrasting with the vibrant orange elephant ear sponges. We’d suggest going in the late morning, the light catches the wall beautifully then, really making the colours pop. Visibility generally holds around 19m, so you get a good sense of the wall stretching out below you. It’s a site that suits anyone looking for a relaxed dive with plenty to observe, whether you’re into macro or just enjoying the reef's overall health.
