The guide

The Capo Carbonara Marine Protected Area surrounds the Villasimius headland and takes in Isola dei Cavoli and the Serpentara islet. It is one of southern Sardinia’s best-loved spots for the clarity of its water and the richness of its coastal seabeds.

For snorkelling from the shore, the rocky sides of Porto Giunco beach and the Punta Santo Stefano area offer mixed granite and seagrass bottoms at comfortable depths, where octopuses and sea breams can be watched just a few metres below the surface.

Boat trips out to Isola dei Cavoli reach more exposed spots, with walls dropping away quickly and more pelagic wildlife. The MPA zoning applies here too: check which areas are open before getting in the water.

This spot lies within a Marine Protected Area: zoning restricts swimming and boating in some stretches. Rely on authorised operators and check the managing body’s current rules.

Getting there and parking

Villasimius is some fifty kilometres east of Cagliari, reached along the SP17 coast road: it is effectively the only way into the beach area, so expect queues in the middle of the day in August.

From June to October the beach car parks are paid: €10 for a car, €15 for a camper and €5 for a motorbike for the full day. From 16:00 the rate drops to €6 / €9 / €3, and blue-badge holders are exempt.

At Punta Molentis access is capped: entry runs from 08:00 to 20:00 and there is room for 90 vehicles at most, so in high season it fills up early.

Where to get in the water

  1. Porto Giunco, rocky side

    You walk in off the sand and reach the granite boulders while staying at comfortable depths: the easiest entry, fine for a first outing with a mask.

  2. Punta Santo Stefano

    Granite and seagrass alternating just below the surface, with octopuses and sea breams a few metres down. The entry is over rock: best on a flat sea, and wear reef shoes.

  3. Isola dei Cavoli

    Reachable by boat only, on the trips leaving Villasimius: walls dropping away fast and more pelagic wildlife, in water where the MPA zoning applies.

Marine protected area rules

  • In zone A (integral reserve) navigation and swimming are forbidden: you do not get in the water at all. The boundaries are marked by yellow buoys at sea and yellow poles on land.
  • In zones B and C swimming is allowed and breath-hold snorkelling is free, within the rules of the zone.
  • Spearfishing is banned across the whole marine protected area, in every zone and all year round.
  • Scuba diving needs authorisation from the managing body: go through an affiliated dive centre.
  • Powered navigation is limited to 5 knots within 300 metres of the shore and 10 knots between 300 and 600 metres.

Services on site

  • The beach has bars and food kiosks plus umbrella and sunbed hire; there is still a free stretch where you can bring your own.
  • Villasimius is a few minutes away and has dive centres and gear rental: anything you are missing can be sorted in town.

Safety

  • Emergencies at sea: 1530 (Coast Guard) or 112.
  • The stretch between the headland and Isola dei Cavoli is crossed by boats and dinghies: stay close to shore and use a marker buoy if you move away from it.
  • With sirocco and levante the sea builds quickly on this side: if the water turns cloudy and the surge picks up, get out.

* The encounter percentages are indicative estimates, worked out by combining each species’ typical habitat with the characteristics of the spot. They are not survey data: whether the fish are actually there depends on the season, the weather, the time of day, sea conditions and, not least, a bit of luck. Always respect marine life and the rules of protected areas.
