Roca Muladera
Also known as: El Catifoll, La Muladera, La Roca del Moro, Muladera, Roca Moladera
Boat dive beside a surface-piercing rock with a canyon, off Tossa de Mar, from 0 to 25 m, with nudibranchs in the canyon and groupers recommended by a local centre.
Last updated October 2026
The dive
The anchor falls into the canyon at 8 metres, and the dive follows that canyon south with the main rock on your left, to a deepest point of about 25 metres. The canyon section sits around 18 metres. The rock reaches the surface on one side and the canyon runs along the other, with a smaller second rock reported to top out near 3 metres, and centres describe backlit walls where light comes in from behind. The route turns at half tank. In the canyon safety stop, nudibranchs are the regular find, with octopus and the occasional barracuda.
What makes it special
One boat position gives two dives. The shallow zone starts at the surface and is wide enough for novices, and divers with air to spare go on into the deeper canyon, so a mixed group can share a mooring and still dive different profiles.
The second draw is the groupers. A Tossa centre recommends the site for seeing them, and a small dusky grouper is possible on the route; around Tossa they are occasional and wary.
Know before you go
Swimming out to the rock is a different dive from the boat trip, because the inner side has a current that sets toward Tossa. Boat departures differ: about 10 minutes from Tossa port with one centre, about 20 from the Mar Menuda area with another, so ask which you are on.

EasyMin cert: Open Water
As of March 2026, one centre sets Open Water as the minimum and two others describe the dive as suitable for all levels; the shallow zone starts at the surface and the deeper canyon section is a choice made from the same boat position.
Summary
Easy in the shallow zone; the deeper section asks for good air consumption.
Safety considerations
What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.
- Current: On a 2010 shore dive, divers leaving the rock's inner side were swept out toward Tossa and swam about 1.5 miles back along the coast; a Tossa dive-club owner had warned against swimming out to the site because of the current there.Reach the site by boat and follow the guide's briefing on direction and exit.

Frequently Asked Questions
Can you swim out to Roca Muladera from the beach at Cala Llevadó?▾
A group did in 2010, descending in the inner channel at 6 m and rounding the rock to its deepest point at 25 m. The current on the inner side swept them out toward Tossa on the way back, and a Tossa dive-club owner had warned against swimming out because of it. The dive is run by boat.
Why is Roca Muladera also called La Roca del Moro?▾
Local fishermen know the rock as La Roca del Moro. Divers write the dive name as Roca Muladera, Roca Moladera or simply la Moladera, so all of them point to the same rock.
