Pilena Reef - Iron Bottom Sound
Seekombuis is a convenient shore entry that works well for those just starting out or looking for an easy dip. We usually surface swim about 150 metres to the main area, which helps conserve air, especially with the maximum depth of 6m. The southern side has a small kelp outcrop where you might spot some nudibranchs, maybe even an octopus tucked away. Visibility averages around 4m, so it’s a site for close inspection rather than big vistas. Think rock fish, cuttlefish, and various sea stars. It’s a pretty calm spot, good for honing buoyancy or testing new gear.
