Pine Cay is a secluded island a little over one mile wide and two miles long, approximately 800 acres in size.
Geologically, the island is a series of low rolling limestone ridges, formed from solidified beach dunes -- older to the east, while still developing on the western shore. The oolitic limestone is created from the consolidation of egg-shaped grains of coral sand. The gray surface is the result of oxidation and algae growth.
