Passages with a View

From the cavern, divers can explore three passages, with two offering short and straightforward routes. The longer passage, known for its incredible visibility (aptly termed Ginnie-vis), boasts an easy entry point with 20 feet of clear visibility.

The Enchanting Manatee Room

The highlight of Arch Sink lies beyond a minor yet steep restriction—a vast room measuring 150-200 feet in diameter and 80 feet in height. The Manatee Room, named after fossilized Manatee bones, features a deep tunnel leading to 195 feet with unique visibility characteristics.

Beware of the Deep Tunnel

While the deep tunnel provides an exciting exploration opportunity, reaching 195 feet, it ends in a silt bottom. Navigating the buried line in zero visibility makes it a challenging exit. The warmth and clarity of the water in the Manatee Room, with reflections from air pockets on the ceiling, create a mesmerizing underwater spectacle.

Unveiling the Underwater Marvel

Arch Sink beckons both seasoned and fair-weather Ginnie divers, offering an unforgettable experience with its unique features and natural beauty.
