Cannon Patch Reef

Cannon Patch Reef is a shallow coral formation off Key Largo known for its historic 18th-century cannons resting among hard and soft corals. Accessible by short boat ride, it’s ideal for snorkelers and novice divers thanks to calm conditions, good visibility, and depths typically under 25 feet. Expect schooling grunts, parrotfish, sponges, and occasional rays or turtles. The site’s compact layout makes navigation easy, and guides often pair it with nearby shallow reefs for half-day trips. It’s best for history‑curious visitors and families seeking a relaxed, photogenic reef experience rather than adrenaline-heavy drift or deep wall dives.
