Roca Partida

Roca Partida is a cleft rock the size of a small building, the visible tip of a seamount standing alone in open ocean - the most concentrated dive in the archipelago because there is nowhere else for anything to be. Whitetip reef sharks lie stacked like cordwood in the wall's few ledges, an image unique to this place. Around the spire, everything rotates: hammerhead schools, silvertips and Galapagos sharks, yellowfin tuna like torpedoes, mantas on their rounds, and in the season's bookends whale sharks. Humpbacks have surfaced beside pangas here. Divers circle the rock, hold in the blue, and try to look every direction at once.

Het moment waar je voor komt: Whitetips shelved in the ledges, everything-at-once pelagic traffic, the loneliest rock in Mexican waters

Topografie: Split guano-white rock spire walls plunging into abyssal water

Stroming: No lee, no anchorage, no bottom in reach - the dive is a circuit of the rock with the current deciding the route.

Gevaren: Full ocean exposure: current, swell, and nothing to hold onto between the rock and the abyss. Strict buddy and DSMB discipline.

Behoud: The long outer leg of the park; weather decides whether boats can stay.

Nitrox: Hier de moeite waard: profielen liggen in het bereik waar nitrox de no-stop-tijd zinvol verlengt (met de juiste training om het te gebruiken).
