Cannons is a historic relic dive for advanced Cozumel divers.
Use an experienced local operator because the dive is condition-dependent and rare.
Cannons is a condition-sensitive east-side Cozumel relic dive where old cannons, anchors, and cannonballs sit on a rough reef edge. It is a special-access boat dive best left to advanced divers with good buoyancy and a flexible plan. The site is more about underwater history and strong-water judgment than a standard drift reef.
