Steel reef is a man made reef created in 2010. Consisting of 4 rough pyramid shaped structures, covered in soft coral. It can only be reached by boat. For a beginner AOW it can be an interesting deep dive, for an advanced diver it does not have a great draw as it has a high nitrogen loading, and short dive time due to depth for little value.
