Mar Menuda
Costa Brava's most-dived shore entry: routes 0-32 m, resident seahorses in posidonia, precoralligenous deep zone, tramontana-proof bay.
Last updated April 2026
The dive
Sa Banyera de ses Dones is a shallow rock pool at the beach's edge, warm and sheltered enough for a pre-dive check in the water. From here the seabed fans in several directions. The classic right route slopes gently through posidonia past resident seahorse colonies onto rocky reef at the Freu channel, the narrow water between shore and Illa de Tossa. Left of centre, El Acuario stays under 15 metres, its sandy shallows and posidonia margins lit brightly enough that local guides compare it to a display aquarium. From 17 metres the precoralligenous zone takes over. That is where the site changes character. Canyons, walls, and a 13 to 20 metre cavern sit within Open Water reach. A short swim across sand reaches La Llosa, a quiet submerged island most groups never visit. Perduts extends to 32 metres for experienced divers. Small nativity figures (belenes) left on the seabed by local tradition serve as navigation landmarks across the larger route network.
What makes it special
Three properties separate Mar Menuda from the other fifty-plus sites around Tossa. The first is route density. From Sa Banyera alone, divers access at least six distinct profiles from one entry: shallow aquarium, mid-zone reef, precoralligenous deep, La Llosa detour, the cavern, and the Perduts extension. Experienced locals estimate around thirty dives to know them all. The second is the Hippocampus specialisation. Two decades of local seahorse observation have produced the world's only PADI Mediterranean Seahorse Expert course, run on the same beds divers swim past on the classic right route. The site is an official stop on the Costa Brava Seahorse Eco-Route. The third is wind. The bay faces south. When the tramontana closes exposed Costa Brava sites, Mar Menuda stays flat. Twenty years of weekend-regular forum chronicles give it the feel of a community dive, not a distant destination.
Know before you go
Summer beach logistics shape the dive. Between roughly 10:00 and 18:30 the municipality restricts equipment preparation at the beach, and fines have been issued for gearing up in the street. Regulars work around it by entering at dawn, around 07:30 to 08:00, into an empty Sa Banyera. Flat water, good visibility, the site to yourself. Spanish law requires diving insurance (roughly 7 EUR a day if not covered elsewhere). Seahorses and every inhabitant of the posidonia beds are protected species that must not be touched or disturbed. The precoralligenous zone from 17 metres sits below the summer thermocline. Bottom water drops to 16-20 C in July and August, so deep routes need at least a 5 mm wetsuit plus hood even in peak season. Shallow routes stay above the thermocline. Night diving requires centre guidance and is worth booking ahead.
