Coast dive on the Costa del Montgrí from L'Estartit, with a beginner wall route and a deeper rock-and-crevice line to 28 m for lobster and crayfish.
Last updated May 2026
A short boat hop north along the Costa del Montgrí from L'Estartit lands above the El Rossinyol buoy. Drop down the line and the topography settles in around 20 metres: rock-and-sand bottom, a defined wall in one direction, an open run of larger formations in the other. The wall is the easier line, and the macro line — octopus tucked into the rock face, cuttlefish drifting clear of it, scorpionfish camouflaged on the lower edges. Open Water buddy teams stay here at moderate depth, follow the wall out and back, and surface on the buoy. The other direction is the rock-and-crevice line, working out across the bottom and stepping down to about 28 metres. This is where the deep crevices hold spiny lobster and European lobster, and where the centres point experienced divers who want the crustacean payoff. The dive concludes back at the buoy for the safety stop. Average bottom time runs to about 45 minutes, and on settled days the site reads as a clean, easy coast dive — the ascent line in plain sight, no permit step, no decompression complications, just a boat ride home.
The dual-route structure is the differentiator on this stretch of coast. Most Costa del Montgrí coast sites publish a single line at one depth band; El Rossinyol publishes two lines from the same buoy, an Open Water wall route alongside an Advanced Open Water rock-and-crevice route, and that lets a mixed-certification group dive together without splitting the boat or running two sites. The print guide of the area lists it as Racó del Rossinyol — the Nightingale's Corner — and the name fits: a quiet nook of the headland coast rather than a marquee site, the kind of dive that earns its keep when the Medes islands are quota-full or wind-cancelled and the boats need a workhorse alternative on the mainland side. The deeper line is the local detail. Centres around L'Estartit point divers to specific crevices in the larger formations at about 28 metres for lobster and crayfish, the kind of payoff that doesn't make a forum thread but rewards a slow, attentive pass with a torch.
Bring a torch and a macro lens. The wall route is octopus-and-cuttlefish territory and the deeper crevices reward light, especially for the crustaceans tucked into the larger holes at 28 metres. Read the day's wind forecast before booking — tramontana from the north can drive flow along this stretch of coast, and centres flag that current sometimes runs at the site. On a flow day the wall route becomes a drift back to the buoy rather than an out-and-back, and the deeper line wants more conservative bottom-time planning. The site is part of the voluntary ecobriefing programme on the Costa del Montgrí, so participating centres run a structured pre-dive briefing on the route and the coast's no-contact rules; ask for it when you book. No Medes permit step, no quota, no per-diver park tax — book the dive as a normal coast departure from L'Estartit and the rest is logistics.
