Costa Brava Divers
PADI 5 Star centre on L'Estartit seafront with stay-and-dive packages, four daily boat dives between Illes Medes and Montgrí, plus tec diving.
Also known as: Puig Sardina
Three-peaked underwater mountain 200 m off the Montgrí coast, with red and yellow gorgonian walls from 14 m past 40 m and pelagic banks circling the peaks.
Last updated May 2026
Most centres run the same profile here: descend the buoy line to 21 m at the saddle, drop to the base of the wall, then climb the mountain in a slow spiral. The discipline is to save the gorgonians for the ascent — air budget collapses fast at 35 to 40 m, and the colour panels are best worked unhurried. The richest cover is on the east and north walls, where red Paramuricea clavata and yellow Eunicella cavolini overlap in layered, dense panels. Hold one to two metres off the rock. The colonies are animals, and a fin strike erases decades of growth.
At the base, dense clouds of Anthias pack the water column around the wall foot — the deeper you go, the thicker they become. Off the peaks, look outward into the blue. Banks of amberjack and horse mackerel circle the structure in summer, and Mediterranean barracuda schools cruise above the saddle. Lobsters press into deeper crevices. The ascent traces the wall toward the shallowest peak, where the safety stop plays out over open Mediterranean blue with the rest of the mountain dropping away below.

Puig de la Sardina is the deep signature natural dive on the Montgrí coast, and the case for choosing it over neighbouring sites is the combination in one location: deep wall structure, gorgonian density that rivals the Medes islands across the water, and pelagic encounters in the blue at the peaks. The access difference from Medes is the practical hook — no permit, no per-diver tax, no quota. Three peaks at roughly 14 m, 22 m, and 27 m give the dive its geometry: a sheltered shallow ascent line, a buoy that lands on the workhorse depth band, and a wall that continues past 40 m for divers carrying gas for it.
Divers compare it favourably to the Medes gorgonian walls. The main difference is the open-water setting — Medes is sheltered and carries resident groupers; Puig is exposed, and the encounters are pelagic. They draw different crowds for different reasons.
The east-facing walls are the panel to work. On the descent, swim past the colour for the deeper turn — Paramuricea-Eunicella overlap is densest between roughly 24 m and 32 m, and a slow ascent gives the gas budget for repeat passes. A torch is essential at this depth. Reds and yellows fade to grey under ambient light at 30 m, and fill light brings the colour panels back. For backdrops with motion, frame the wall and watch the blue. Amberjack banks pass the structure in summer, and the Anthias clouds at the wall base give life to the deep frames. Wide-angle suits the layered wall panels; macro works the lobster crevices and moray faces.
Depth creep is the first thing to manage. The wall drops past 40 m with no shelf to catch a distracted descent, so set a maximum depth before you enter and stick to it. EAN32 is the centre-standard mix and stretches usable bottom time in the 25 to 35 m band. Carry a torch for the gorgonian panels and the lobster crevices. The site is an exposed offshore pinnacle — bring an SMB and brief the surface-recovery plan before entering, because the tramontana can push divers off the buoy line. Hold one to two metres off the wall throughout. The park rules apply across the coast: no anchoring on Posidonia, no feeding, no collecting.
What makes this dive site stand out.
Crests at roughly 14 m, 22 m, and 27 m rising from a seabed past 40 m
Red and yellow Paramuricea-Eunicella cover ranked with the richest on the Costa Brava
Amberjack and horse mackerel circle outside the structure in summer and early autumn
Inside the Natural Park but free of the Medes permit, quota, and per-diver tax
Fixed mooring over the saddle; descent line lands on the workhorse depth band
42.0734°N, 3.2081°E
Summary
Depth is the limiting factor. Buoy at 21 m, workhorse band 25-35 m, wall continues past 40 m. Tight air management and good buoyancy control are non-negotiable on the wall.

The Medes-zone per-diver tax does not apply on the Montgrí coast.
No. The site is 200 m off the Montgrí coast, inside the Parc Natural del Montgrí, les Illes Medes i el Baix Ter, but outside the strict Reserva Natural Parcial of the Medes islands. The Medes permit system and the per-diver tax do not apply. You pay only the operating centre's service fee.
The richest cover sits between roughly 21 m and 35 m on the east and north walls. Diving to 30 to 35 m is enough to see the full display. The wall continues past 40 m, but the Paramuricea-Eunicella overlap does not require that depth to appreciate.
Advanced Open Water is the practical minimum for an independent dive. The buoy sits at 21 m and the workhorse band is 25-35 m. Open Water divers may dive only when accompanied by a 3-star diver or instructor. The Deep Diver speciality opens the wall to 40 m.
June to October is the active window. Amberjack and horse mackerel circle outside the structure, not on the wall, so look outward into the blue at the peaks. Barracuda schools cruise above the saddle through summer and into early autumn.
Yes. At 25-35 m the reds and yellows of the gorgonians fade under ambient light, and a torch brings the colour back. It also lets you inspect the crevices where lobsters shelter along the deeper wall.
The gorgonian cover here ranks with the richest on the Costa Brava. The Medes walls sit inside the strict reserve and carry the resident grouper population; Puig is an open-water seamount with pelagic encounters at the peaks. Different setting, comparable wall density.
