Port Wall

Port Wall lies along the leeward coast of Cozumel, an island off the Yucatan Peninsula in Quintana Roo, Mexico, within the marine park running along the island's southwest shore. Dive sites along this stretch are typically reached by boat from San Miguel de Cozumel and sit along the same shelf that drops into deeper water as part of the Cozumel wall system. The site reaches a maximum depth of around 30 metres and is rated an advanced dive, with visibility generally reported as great. The bottom here includes cave terrain, and divers have noted fragile formations along with overhead sections that call for caution when moving through them.
