About this site
Alcatraz Reef is a reef dive site in the waters of Coron, Philippines, featuring an expanse of hard and soft corals that form a varied underwater landscape across a depth range of 5 to 30 metres. The reef's topography includes overhangs and small caves alongside broad coral gardens, giving the site a dynamic structure suited to open-water-level divers.
Marine life at Alcatraz includes schools of colourful reef fish, nudibranchs, and occasional larger pelagic visitors such as barracudas and trevallies.
