About this site
Cement Wall in Zanzibar offers a dramatic drop-off plunging into the deep blue. The wall is covered in vibrant soft corals and sponges, attracting schools of reef fish, lionfish, and occasional reef sharks. Strong currents make this an advanced dive, but the visibility is often excellent. The site's name comes from remnants of an old concrete structure now encrusted with marine life. Expect thrilling drift dives along the wall with sightings of turtles and large pelagics.
