Key Dive Site Facts
Dive Site Overview
Exploring Cala Abierta unfolds as a tranquil journey into Cartagena's underwater realm, situated strategically east of Cala Cerrada. Divers here encounter a notably mixed seabed composition, transitioning between areas of substantial boulders, intricate rock formations, and wide stretches of sand and fine gravel.
Providing a dynamic backdrop for exploration, the terrain varies significantly. A dominant ecological feature is the expansive meadow of Posidonia oceanica, whose vibrant green fronds sway gently, serving as a crucial habitat and nursery ground for a diverse array of smaller marine species. Depths within the site reach approximately 24 m (79 ft), yet many rewarding explorations occur within the shallower regions, perfectly accommodating both novice divers and those refining their buoyancy skills.
A natural configuration, perceived as more open and expansive than adjacent coves, inherently offers a sense of calm to the bay. Its well-sheltered position consistently results in mild conditions, characterized by minimal currents, which makes it an ideal location for educational dives, equipment checks, or simply a relaxed leisure dive.
As a welcoming stop for local dive excursions, the site benefits from its reliable accessibility and serene environment.
Best Time to Dive
