Pota del Llop

Deepest dive in the Medes reserve — a north-east gorgonian wall on Meda Gran dropping to 50 m, weather-gated and less-dived than its neighbours.

Last updated May 2026

The dive

The rock formation named for the wolf's paw silhouette above the waterline sits on Meda Gran's north-east tip, and the dive it gives is the deepest in the reserve. The descent lands on a gorgonian-carpeted wall from around 20 m, with red Paramuricea clavata across the face and the upper ledges offering a macro stop for nudibranchs on cooler stretches. The route runs the wall. Past 25 m the gorgonian cover thickens, large fans described by local centres as stretching as far as you can see. The wall keeps going past 40 m. At the deepest point a small cave opens, and from inside a short chimney rises back up the rock — the structural feature that separates this dive from Pedra de Déu next door. A torch brings the cave to life and marks the natural turning point for the profile. The return climbs the wall. Because the site sees far fewer dives per season than the south-facing Medes points, groupers and octopuses tend to hold their ground rather than retreating into crevices, and dentex pass on hunting runs without the reflex flight that crowds produce.

What makes it special

Three things set Pota del Llop apart from the rest of the Medes wall sites. Depth is the first: the wall here drops to a sand base around 50 m, and local centres explicitly flag it as the deepest point in the reserve — territory where the bottom sits well past recreational planning depth. The cave-and-chimney is the second: Pedra de Déu has denser gorgonian canyons, Carall Bernat has the open-water pinnacle and the grouper clusters, Pota del Llop has the overhead feature. The third is traffic. North-east exposure closes the site routinely, and the lower dive frequency changes the wildlife dynamic. A Spanish diver's 2012 account of using this wall to push a backup regulator to 50 m captures the site's character: experienced local divers choose it not for ease but for depth, challenge, and the kind of encounter that comes when fish aren't used to being visited every morning.

Know before you go

Conditions decide whether the dive happens, and they decide it late. Build flexibility into any Pota del Llop booking — centres swap to a sheltered Medes alternative when north or east wind builds, sometimes on the morning itself. Set a maximum depth on the boat, not at the wall. The base at 50 m is beyond recreational limits and the gorgonian slope is easy to follow past the turn. Run EAN32 below 25 m. The cave-and-chimney is a structural feature, not a penetration dive, but it is still overhead; carry a torch and approach it only with a buddy who is on the same plan. The upper wall is the macro stop on the way back up. Reserve rules apply in full: 5.30 EUR per-person fee per dive, daily quota enforced, mandatory eco-briefing, no feeding or touching, 1.5 m minimum standoff from walls and bottom, and night diving prohibited throughout the reserve.

Why Dive Pota del Llop

What makes this dive site stand out.

  1. 1
    Deepest dive in the reserve

    Wall drops past 40 m to a sand base around 50 m, beyond standard recreational limits

  2. 2
    Cave and chimney at depth

    Small cave near the wall base opens into a short chimney rising back up the rock face

  3. 3
    Gorgonian wall

    Paramuricea clavata covers the vertical face from around 20 m down

  4. 4
    Weather-gated access

    North-east exposure means tramontana or levante closes the site, often on short notice

  5. 5
    Less habituated wildlife

    Lower traffic than south-face Medes sites; resident fish hold ground differently here

Frequently Asked Questions

Why does Pota del Llop cancel so often?
The site sits on Meda Gran's north-east tip, directly exposed to tramontana from the north and levante from the east — the two winds that most often close diving on the Costa Brava. Either one builds surface chop quickly on this face and the boat does not run. Because those winds are common, the site dives far less per season than south-facing classics like La Vaca or Carall Bernat. Even confirmed bookings can be swapped to a sheltered alternative on the morning.
How deep is the wall at Pota del Llop?
The wall drops past 40 m to a sand base around 50 m. The upper 20-30 m section carries the densest gorgonian cover and is divable on Advanced Open Water in calm conditions. The full profile to the base is run by experienced advanced or technical divers with Nitrox; 50 m sits beyond standard recreational planning. Agree your turn depth on the boat before descent.
What is the cave like at Pota del Llop?
A small cave opens near the deepest point of the wall, and from inside a short chimney rises a few metres back up the rock face. It works as a natural turning point for the deepest leg of the profile rather than a penetration objective. A torch is essential, and the overhead environment means you should approach it only with appropriate training and a buddy on the same plan.
Is the marine life better here than at other Medes sites?
Different rather than simply better. The site's weather-gating means it sees fewer dives per season than the daily-traffic sites, and the resident groupers, dentex, and octopuses tend to be less habituated to divers. Photographers willing to commit to a deep, weather-uncertain dive get cleaner natural-behaviour encounters. The trade-off is that the boat does not always go.
Do I need Nitrox for Pota del Llop?
Centres strongly recommend EAN32 for any profile below 25 m and most operators assume you have it before booking. Without Nitrox the dive effectively narrows to the upper 20-25 m wall, and most of the gorgonian face stays out of reach within safe bottom-time limits.
Can I see eagle rays or sunfish here?
Possibly, not reliably. Older Spanish-language centre pages mention eagle rays at the site, and very occasional summer sunfish sightings are part of the wider Medes wall picture. Neither species is a statistical bet on any single dive. Treat both as a pelagic bonus — a reason to look into the blue at the wall edge, not a reason to choose the site.
What permit and certification do I need?
Reserve sites require at least second-class certification, the European AOW equivalent — Open Water training dives and try dives are not permitted inside the Medes. Every diver pays the per-person reserve fee (5.30 EUR per dive in 2026) and the daily quota is enforced, so book through an authorised centre in advance, especially in summer. The centre handles permit paperwork and the mandatory pre-dive eco-briefing.
