Illa de Tossa

Canyons carved by rock tongues define the east wall of the island. Descent from the mooring lands at 14 metres, where the near-side route traces the contour of the peak. White gorgonian fans spread across the rock face, perpendicular to the flow and thickest between 15 and 22 metres. Schools of bream, damselfish, and salps fill the midwater along the wall. Small nativity figures placed by local tradition sit on the seabed at intervals, anchoring the route. The full circumnavigation returns to the mooring without retracing ground, and the gorgonians show a different face from each angle. A typical circuit runs 40 to 50 minutes.

Two dives live on one mooring line. The near-side circuit is a wall dive built around white gorgonians in concentrations rarely matched at recreational depths elsewhere on the Costa Brava. Cross to the far side and the character shifts: open water replaces shelter, a chain of detached rock ridges runs north to south at 30 metres, and the rock transitions to pre-coralligenous cover. Between these extremes sits the La Caida route, a vertical drop covered in yellow encrusting anemone and pale dead man's fingers projecting from the rock. Locals who return year after year call it a site that always surprises. Against its neighbours, the distinction is clear. Mar Menuda offers sandy posidonia and a beach entry. Roca Muladera carries the grouper reputation. Illa de Tossa carries the gorgonian walls and the canyon geometry.

The upper wall at 14-18 metres suits any Open Water diver. The full near-side circuit reaches 24 metres and requires Advanced Open Water certification. The far side demands different planning: at 30 metres on the seaward face with fewer reference points, the turnaround rests on air and depth awareness. On a first visit, start with the circumnavigation to read the site before committing deeper. Dream Dive caps guided groups at four divers per guide. The island sits inside Mar Menuda bay facing south and stays diveable when tramontana closes exposed sites. Nitrox extends the deep route. Below the summer thermocline, water at 30 metres drops to 16-20 degrees despite a warm surface, so plan exposure protection accordingly.
