About this site
Knife sits along the coastline of Grand Cayman, part of the network of reef sites ringing the island that are typically reached by short boat trips from local operators. It is a shallow reef dive, with a maximum depth of around 4.6 metres, making it well suited to relaxed, unhurried exploration close to the surface. Divers have reported angelfish, damselfish, lizardfish, and parrotfish around the reef here. Grand Cayman's shoreline in general is marked by fringing reef and drop-offs a short distance offshore, and this site sits within that same shallow reef structure.
