Bloody Bay Marine Park is defined by its walls. A shallow reef platform sits just below the surface before plunging into deep water, and this pattern repeats across nearly every site in the area. The majority of diving and snorkelling is accessed by boat. Intermediate divers will find the most variety, from drift sites like Bus Stop and Donna's Delight to the cave topography of Cumber's Caves and the canyon at Lea Lea's Lookout. Great Barracuda, Fairy Basslet, and Caribbean Spiny Lobster appear across the full range of sites.

Water stays warm throughout the year, climbing to its peak through the late summer and early autumn months. Conditions are generally favourable year-round, though the data points to late spring as a particularly well-regarded window. Mild currents at drift sites like Bus Stop and Donna's Delight suit intermediate divers comfortable managing flow along a wall.
