Petra Piomba

Petra Piomba is a granite climbing crag in the commune of Olivese, in the Corse-du-Sud region of southern Corsica, not far from Propriano. Despite sitting well off the main roads, it has earned a reputation among climbers across the island as an essential stop on any Corsican rock-climbing circuit.

What is Petra Piomba?

The crag spans roughly 9,000 square metres, with most of its routes bolted between 1995 and 2004. The rock is granite, offering the sloper and flat-hold style typical of the stone, and the wall mixes steep overhanging sections with more classic vertical faces. Routes typically run around 20 metres, with the tallest lines reaching up to 35 metres.

How many routes are there, and how hard are they?

Depending on how you count, the site holds somewhere between roughly 25 and just under 50 established routes, ranging from around grade 5c up to 9a — including a handful of hard projects that remain unrepeated to this day. The crag's signature lines start around grade 6b, though gentler options exist as well.

The area is split into a few distinct sectors. The most highly regarded is "Toit" (Roof), a steeply overhanging section with notably better rock quality and varied movement, which also happens to keep climbers dry in the rain. Another sector, nicknamed "Mort de brosse," has rougher, coarser stone by comparison. In autumn 2016, new multi-pitch routes were added in the roof sector, pushing into grade 9 territory — climbs that, as of now, still await a first repeat.

How do you get to Petra Piomba?

The approach starts on a path from the northeastern edge of Olivese village, running parallel to the D26 road. The trail crosses the Valdu ravine before reaching the crag, and the whole walk from the parking area takes about 20 minutes. It's short but worth doing in proper footwear, especially after rain.

When is the best time to visit?

Because the overhanging "Toit" sector shelters climbers from rain, part of the crag stays climbable even in wet weather, making Petra Piomba more or less a year-round destination. That said, spring and autumn offer the most comfortable temperatures in southern Corsica, while the rock can get quite hot under the summer sun.

Who is this crag for?

Petra Piomba mainly draws experienced climbers looking for demanding, overhanging lines from grade 6b upward. Newer climbers aren't left out, though — the left side of the crag offers mellower, less overhanging routes in the 5th and 6th grade range.
