Mont Senino

Mont Senino is a 618-metre summit rising above the commune of Osani on Corsica's west coast, between the Gulf of Porto and the Gulf of Girolata.

How do you get there?

The trailhead sits at Col de la Croix, within the commune of Osani. From there the path first climbs to the neighbouring peak of Punta Castellacciu (585 m) before continuing on to Mont Senino itself. The round trip covers roughly 6 kilometres, but around 400 metres of elevation gain makes the walk feel more demanding than the distance suggests. Cars can reach the area near the start of the trail, from which point the hike continues on foot.

What will you see?

The summit opens onto a sweeping panorama approaching 360 degrees, taking in the area around Piana, the famous calanques rock formations, the Gulf of Porto, the Gulf of Girolata, and the Scandola nature reserve. This combination of jagged ridgelines, deep blue sea, and untouched coastline makes Mont Senino one of the more striking viewpoints on this stretch of Corsica, even though the peak itself isn't among the island's tallest.

The trail runs through genuinely mountainous terrain: it's steep, marked mainly by cairns, and between Punta Castellacciu and Mont Senino there are sections that call for scrambling, including a narrow rock chimney. This gives the route more the character of an orienteering-style mountain trek than a simple walk, demanding good route-finding skills and confidence on exposed rock.

When should you visit?

Because the trail is steep, exposed, and largely without shade, it's best to avoid the hottest part of the day during peak summer — conditions are already physically demanding, and heat adds extra strain. Spring and early autumn tend to offer more comfortable temperatures for the climb, along with some of the clearest views toward Scandola and the surrounding gulfs. Given the exposed, rocky terrain, it's also worth avoiding days with strong wind or after rainfall, when the rock surfaces turn slippery.

Who is this hike for?

Given its technical difficulty and the scrambling sections involved, the climb to Mont Senino is recommended mainly for experienced mountain hikers. Less experienced walkers can turn back at Punta Castellacciu — the views from there are already excellent, and the approach up to that point, while steep in places, doesn't require any climbing skills and is far more accessible.
