Cromosomi Corsari

Pedra Longa (Baunei) · Sardinia · Italy

Bail with caveatsBolting confidence: high

A sea-level start reached by abseil, then seven short pitches up the seaward face of Pedra Longa. The third pitch is a wildly exposed traverse above a line of roofs; two easy pitches on rock that needs care lead to a technical 6b and 6b+ finish on grey slab.

The route

Overview

Cromosomi Corsari climbs the south-east face of the Pedra Longa stack from a rocky cove at sea level to the summit. Maurizio Oviglia, who opened it with Fabio Erriu in 2014, describes it as a marine Dolomite climb: varied, athletic and very exposed above the water, with a few short sections of rock that need attention. The hard climbing comes in two blocks, pitches 2 and 3 and then pitches 6 and 7. It has become a classic, with chalk on the holds, and recent parties find the grades friendly and the bolts close.

The climbing

Pitch by pitch

Pitches of Cromosomi Corsari
PitchGradeLengthNotes
P15c25 mFirst runner on a thread with red cord, then a slightly rising traverse to the corner on the right and a mantel. Do not traverse far right under the bush (that is Il richiamo del mare) and do not go straight up the other bolt line. PlanetMountain gives 5c+. Extend runners to limit drag.
P26a+20 mGo right, climb the corner on orange rock and follow the obvious crack to a polished slab. PlanetMountain gives 6a+/6b.
P36a+15 mThe showpiece: a rising traverse right along good horizontal breaks above the roofs, with the holds shrinking as you go, to a belay on a prow. Closely bolted. PlanetMountain gives 6b/6b+.
P44c15 mFollow the strata on good horizontal holds; test the blocks. Given 4+ on camptocamp.
P55b15 mShort walls on grey rock, again with some blocks to treat carefully. Pitches 4 and 5 link easily.
P66b20 mA physical overhanging start, a hard traverse left, then easing up a fine grey slab to a comfortable belay.
P76b+20 mA technical grey wall straight above the belay, with the crux on the slab by a badly placed bolt. Belay below the summit. PlanetMountain gives 6b; several logbook entries find it the hardest pitch.

Getting there

Approach

To the parking

From Baunei take the SS125 towards Santa Maria Navarrese and turn off at the sign for Pedra Longa; follow the road down to the car park by the bar-restaurant (40°01'38.9"N 9°42'21.3"E).

On foot · about 10 min

About 10 minutes plus one abseil. From the car park take an unmarked path up through the scrub (east on camptocamp, south on PlanetMountain) onto a narrow ledge. Pass a notch and follow the ledge down, ignoring an abseil rigged on a tree to the right. Just after it there is a cairn, then a descent on the right to a chained stainless abseil station on the left, on the true right side of the cirque. Do not cross or climb the cirque above the route, even though there are bolts with maillons there. One abseil of about 20 m reaches the rocky beach. The name is written at the base; the start is shared with the lines immediately left and right.

Getting down

Descent

From the top of the route go to the summit and descend the normal route northwards along the crest (cairns, grade II downclimbing), or find the abseil on the edge of the north face that avoids the climbing sections in 30 m. Rejoin the steps and the single-pitch sector and walk up to the car park, about 20 minutes.

Retreat

Bailing off the route

Bail with caveats

PlanetMountain says you can descend the route as far as belay 3, with some acrobatics because of the traverses; above that it is better to finish and walk off. Abseiling returns you to the sea-level cove, from which the way out is to climb a route or, by one logbook account, a traverse along fixed ropes above the water.

Retreat from
Belays 1 to 3, by abseil with care on the diagonal pitches.
Point of no return
Belay 3, after the roof traverse. From belay 5 the remaining two pitches are the hardest on the route.
Carry
Two half ropes are recommended for a retreat. Maillons in case stations are not rigged.
Basis
Stated in the sourcesPlanetMountain's route page; the exit from the cove by fixed ropes comes from a single Climbing Italy logbook entry.

Safety

Hazards

  • Abseil approach to a cove at sea level. Finding the right station matters: parties in 2019 and 2025 first abseiled from a single bolt with a maillon on unstable ground. Use the chained stainless station.
  • Loose rock on pitches 4 and 5 and near the top. Climbing Italy stresses not pulling on rock off the line.
  • The second can take a pendulum on the pitch 3 traverse and at the start of pitch 6.
  • Do not throw or knock stones into the cove in the bathing season: there may be divers and swimmers below.
  • PlanetMountain advises attempting it only if you are solid at 6b. The 6b+ is obligatory at about 6a+.
  • The descent by the normal route has exposed downclimbing and an abseil station that is easy to miss.
  • Sea state at the base is not discussed in the sources, but the start is on rocks at the waterline.

Sun and weather

Conditions

South-east face, low above the sea. PlanetMountain says the route is almost always in the sun. An April 2019 party climbed the lower pitches in morning shade and met the sun at pitch 4 on the east-facing arête; an April 2025 party climbing in the afternoon found it hot. Choose cool days outside summer.

What to carry

Gear

12 to 14 quickdraws, some extendable, and slings. A single rope works; PlanetMountain suggests two half ropes as better for a retreat. Optional medium cam for the second's benefit on pitch 3. Helmet.

Worth knowing

Tips

  • Allow about 4 hours 30 car to car at a relaxed pace; one fast party took 2 hours 30 on the route.
  • A logbook entry mentions an alternative to the abseil: a traverse about 5 m above the water along fixed ropes, with loose rock and slippery sections.
  • The hardest moves can be aided: one party logged it as 6a+ A0.

Open questions

Where sources disagree

  • Pitch grades: camptocamp gives 5c, 6a+, 6a+, 4+, 5b, 6b, 6b+; PlanetMountain gives 5c+, 6a+/6b, 6b/6b+, 4c, 5b, 6b, 6b, putting the 6b+ on the traverse and not on the last pitch. Camptocamp grades are used here.
  • Length: 175 m (PlanetMountain, Climbing Italy), 170 m on camptocamp, whose pitch lengths add up to only 130 m.
  • Approach abseil: about 20 m in most sources; one logbook entry says 30 m.
  • Quickdraws: 12 (PlanetMountain) or 14 (camptocamp).
  • Cams: camptocamp and logbooks say none needed; PlanetMountain mentions an optional medium cam on the crux traverse.

Marinaio di Foresta

An airy, mostly left-rising traverse that spirals round the Pedra Longa sea stack to its summit, on water-runnelled grey walls and pocketed white rock right above the sea. It has become one of the most popular routes in Sardinia, so expect queues.

Easy Gymnopédie

This is the easiest way to the top of Sardinia's iconic 140 m pinnacle above Cala Goloritzè. Short technical bulges and walls lead to a fine slab finish, and the harder overhangs can be aided. Gulliver splits it into 4 pitches; camptocamp gives 5. Check seasonal access rules for Cala Goloritzè before going.
