Roca Muladera

Two rocks frame a canyon at 8 metres where the anchor sits. The larger rock breaks the surface; the secondary one rises to 3 m. Heading south with the main rock on the left, the canyon walls close in and sunlight enters from behind. Dream Dive calls the backlighting magnificent. Morays and conger eels occupy the crevices. Nudibranchs cluster on the wall surfaces, rewarding a slow pace. At 24 m the canyon opens to sand. This is where the groupers tend to be. The return follows the opposite face of the main rock at shallower depth. The half-tank rule works well here: turn at 100 bar and track back up the canyon. Lobsters and octopus keep the safety stop productive.

TossaSub rates this the top dive on the Tossa seabed. The grouper association is specific to this site. Of all the Tossa boat points, Roca Muladera is the one where local centres set the expectation that a dusky grouper sighting is a reasonable outcome, not a lucky break. The canyon layout gives the dive a second draw. Distinct formations at different depths create a natural orientation exercise, and TossaSub explicitly recommends the site for navigation practice. Beginners stay in the shallow section. Divers with good air consumption take the deeper route. The guide flexes the plan to the group. A 2010 community trip report captures the site's pull: "there was so much life we've decided to come back next Saturday."

Boat only. Ten minutes from Tossa port, longer from Lloret. Do not attempt a shore swim: a local club owner warned a group that the current made it unsuitable, and the group who tried it compared the experience to Navy SEAL training. Air management matters. The deeper canyon sections sit at 20-25 m. Start deep, ascend gradually. The site is exposed between Tossa and Lloret, so strong northerlies (tramontana) or easterlies can cancel the dive. Centres substitute Mar Menuda on those days. Macro photographers should bring a torch for the nudibranch crevices. Wide-angle works for the backlit canyon.
