Big Wall
Why dive here
With 41+ marine species recorded in the area - including humpback whales, sea turtles, spinner dolphins, napoleon wrasse and pufferfish - Big Wall offers some of Dar es Salaam & Offshore Islands's richest wall diving. Water ranges 26-29°C, warmest March, April, December.
Big Wall, as the name suggests, offers exactly that: a substantial drop-off that draws you down. You’ll find a mix of smaller reef fish hugging the wall, like Indo-Pacific sergeants darting around, and if you keep your eyes peeled, we’ve spotted eroded cowries tucked into crevices. It’s a good spot for a relaxed drift, letting the current do some of the work, and the depth allows for some decent bottom time if you're mindful of your no-decompression limits. This site is a solid choice for those who appreciate the geology of a dive as much as the critters.
