Na Bosca

Two rocks sit side by side a few minutes from Mar Menuda beach, one large, one small, with a sand-bottom canyon running between them. The standard route traces a figure-eight: descend to the base of the larger rock at around 16 m, follow its contour upward along walls lined with crevices, then cross the sand channel to loop around the smaller formation. Conger eels and moray eels peer from gaps in the rock. Lobsters tuck into the darker recesses. The sandy crossing between the two rocks demands careful finning to avoid kicking up sediment, but the route itself needs no compass work. Most divers surface after 40 to 50 minutes.

On the outermost face of the larger rock, a dense school of white seabream holds position. The fish hover in a calm mass over the rock surface. For photographers, this is the shot. The school stays put, which gives time to compose rather than chase. Na Bosca is also one of the documented seahorse sites in Tossa de Mar. Local dive guides have filmed specimens here and singled them out as standouts for the area. Between the seahorses, the bream school, and the variety of invertebrates in the canyon, this site packs a lot of subject matter into a shallow, relaxed profile.

Na Bosca is a boat dive. The ride from Mar Menuda is short, but there is no practical shore alternative. Several centres in Tossa de Mar run regular trips here. Pricing ranges from around 35 EUR to 54 EUR per guided dive depending on the operator and equipment included. Diving must be done through a licensed centre. Night dives have been run here, and the area's nocturnal life includes juvenile octopuses and lobsters, though not every centre offers this option regularly. Summer thermocline means the bottom at 21 m can be 16-20 C even when the surface feels warm. A 5 mm wetsuit handles most summer dives, but consider thicker neoprene for extended time at depth.
