Joshua Swash - Roatán

Mbungu is our go-to site when we’re feeling a bit lazy and just want to drift along. It's a proper gentle current cruise, starting shallow and just letting you float down to about 18 metres. We love how the reef here is mostly soft corals, swaying with the water movement – the whole place feels alive, especially when the light filters through. Keep an eye out for the Maori wrasse; they're often lurking in the coral bommies. We’ve had some fantastic encounters here with green turtles, just munching away on the seagrass at the sand patches near the reef edge. It’s also a good spot for nudibranchs if you slow down and actually look; we’ve found a few unusual ones tucked into the crevices. The visibility can be a bit variable, but on a good day, it’s 15 metres and you can see the whole reef structure unfold beneath you. It’s ideal for newer divers wanting to get comfortable with a drift, or anyone who just wants a relaxing, colourful dive without too much effort.
