Scuba here is about small-scale Mediterranean exploration: reserve permits, rocky coves, island walls, posidonia meadows, swim-throughs and boat dives rather than big-resort infrastructure. Denia operators such as Mon Diving work the Cabo de San Antonio side, while Xabia/Javea operators use Portitxol, Granadella and nearby cove routes. Visibility is often best after calm weather, but it can drop after wind, swell or runoff. Most visiting divers should book guided dives, because the marine reserve rules, boat traffic, entry points and wind exposure are easier to manage with local knowledge.
The south side of Portitxol Island is known for posidonia, boulders and varied fish life.

A compact, crystalline Xabia cove that works well for shallow reef, training and guided beginner dives when sea state allows.
Denia's rocky Les Rotes coast gives easy visual context for the reserve: ledges, boulders, posidonia and snorkeltoscuba terrain.
Cabo de San Antonio Marine Reserve
The destination's signature protected cape, with rocky walls, sandy passages, posidonia, caves and fish refuge habitat.

Operator Checklist
Book early for July and August, and ask whether the planned dive is inside the marine reserve. Confirm that the operator handles the required authorization. Build a spare day for wind-related site swaps. Summer water can be comfortable in a 3mm to 5mm suit, while winter divers often prefer 5mm to 7mm plus hood. Bring certification card, insurance details, DSMB, cutting tool, hard-sole booties and a compact torch for overhangs. Do not anchor privately in the reserve, do not collect marine life and keep fins clear of posidonia.
