Dive Site 1: North Dry Rocks
Our morning session began at North Dry Rocks, a shallow reef system perfect for both divers and snorkelers. The visibility was exceptional today, reaching nearly 50 feet, allowing for a clear view of the sprawling Elkhorn coral formations. Divers encountered a massive school of Blue Tangs moving across the reef, while several Nurse Sharks were spotted resting under the ledge overhangs. The surge was minimal, making for a relaxed, easy-paced exploration of the inner reef.

Dive Site 2: Key Largo Dry Rocks (Christ of the Abyss)
For the second submerged stop, we visited the iconic Christ of the Abyss statue. The site remains a favorite for its combination of history and marine biodiversity. The bronze landmark was surrounded by vibrant Parrotfish and several friendly French Angelfish that approached divers closely. We also noted a healthy presence of Spiny Lobsters tucked into the crevices of the surrounding reef fingers. The sunlight piercing through the shallow water provided perfect natural lighting for underwater photography.

Marine Life Observations
Large Species: Three Reef Sharks (patrolling the outer edge), two Green Sea Turtles.

Macro/Small Life: Numerous Spotted Drum fish, Flamingo Tongue snails, and vibrant Christmas Tree Worms.

Reef Health: High activity noted in the soft coral gardens with minimal sediment disruption.

Staff Note: Visibility is expected to remain high through the weekend. We have a few spots remaining for our afternoon wreck charters—please check in at the shop or call to confirm your equipment needs before departure
