Roca d'en Pep

Crevice-rich rocky ridge at 4-22 m parallel to Tres Barres off Tossa de Mar, with posidonia meadow behind and an 8 m gap linking both sites.

Last updated April 2026

The dive

Ten minutes from Tossa port, the boat sets you over a long rocky ridge (barra) running parallel to the coast. The top of the ridge starts at 4 metres. Drop along its flank and the crevices begin immediately. Morays peer out from deep holes. Lobster antennae twitch in the darker recesses. Octopus move between gaps. The mid-section at 14-16 metres is where most of the dive plays out, the rock riddled with life at every scale. Scorpionfish sit motionless on ledges. Brotolas retreat deeper as your torch finds them. In the water column between the formations, damselfish and salps school in shifting clouds of colour.

For divers managing their air well, the 8-metre crossing to Tres Barres opens a second reef of similar character. The deeper end of the ridge reaches 22 metres, where additional standalone rocks extend the terrain beyond the main formation.

What makes it special

This is a companion dive, not a solo headline. Roca d'en Pep and Tres Barres form a twin rock bar system close enough to link on one tank. The crossing is the draw. Eight metres of open water, a short swim at mid-depth, and you have doubled your terrain. Behind both bars, the landscape changes entirely. Posidonia meadow replaces granite, and the residents shift with it. Rays glide over the seagrass year-round. In winter, John Dory patrol the sand-grass boundary. The combination of crevice reef and seagrass habitat within a single dive profile is uncommon among Tossa's boat sites.

Know before you go

Boat dive only, run by local centres from Tossa port. TossaSub lists Roca d'en Pep by name. If the two-site crossing interests you, mention it when booking. Air consumption is the deciding factor. The shallow average (14-16 m) is forgiving, but linking both bars on one tank requires discipline. A torch reveals the best of the crevice life. Summer water is 24-26 C at the surface but drops to 16-20 C below the thermocline at depth. A 5 mm wetsuit is fine for the shallows; plan for the temperature difference if exploring the deeper sections. Winter brings 13-15 C water but visibility stretches past 20 metres.

Frequently Asked Questions

Can I dive Roca d'en Pep and Tres Barres in one dive?
The two rock bars sit roughly 8 metres apart. Divers with good air management can cross the gap and explore both formations on a single tank. Your guide will judge whether conditions and the group's experience allow the crossing.
Is Roca d'en Pep suitable for beginner divers?
The site is described as suitable for all levels. The shallowest sections start at 4 metres, comfortable for recently certified Open Water divers. Deeper areas toward 22 metres reward more experienced divers with additional rock formations to explore.
What marine life will I see at Roca d'en Pep?
The rock bar's crevices shelter large morays, spiny lobsters, octopus, scorpionfish, and brotolas. Damselfish and salps fill the mid-water. Behind the bars, a posidonia meadow hosts rays year-round and John Dory in winter months.
How does Roca d'en Pep compare to Tres Barres?
They are parallel neighbours separated by about 8 metres. Tres Barres has three distinct rock bars with channels and is known for nudibranch diversity on its safety stop rock. Roca d'en Pep is a single bar with more scattered surrounding rocks and a posidonia meadow behind. Similar depth range and difficulty.
When is the best time to dive Roca d'en Pep?
May through October for warm water and active marine life. September-October combines warmth with improving visibility and fewer boats. Winter diving offers the best clarity (20-30 m) and a chance to spot John Dory in the posidonia meadow, though water drops to 13-15 C.
Do I need a permit or certification to dive here?
No permit is required. Tossa de Mar has PEIN and Natura 2000 environmental protection but is not a marine reserve. Open Water certification is the minimum for the shallow sections. The deeper areas to 22 m are best suited to Advanced Open Water divers.
Should I bring a torch for this dive?
A torch is strongly recommended. The rock bar is full of holes and crevices where morays, lobsters, and scorpionfish shelter. Without a light, you will miss much of the life that makes this site interesting.
