Hiking

Embark on the Larian Triangle Ridge Crest Trail, a moderate hike that guides you through varied scenery. You will start in tranquil woodlands, transition into open meadows, and then ascend along scenic ridgelines. The terrain becomes increasingly stony as you approach the Monte San Primo Summit, the highest point in the Larian Triangle. This route covers 4.7 miles (7.6 km) with an elevation gain of 1894 feet (577 metres), typically taking around 3 hours and 28 minutes to complete. From the summit, you are rewarded with sweeping panoramic views of Lake Como and the surrounding Alpine peaks.

To begin your hike, head to the small mountain hamlet of Piano Rancio, which is easily accessible and located about a 20-minute drive from Bellagio. You will find convenient parking available directly at the trailhead in Piano Rancio. Planning an early start is advisable to fully enjoy the trail's offerings and secure a parking spot, particularly on busy days. Always check local conditions before you go, especially regarding weather changes at higher elevations.

This trail is a highlight for anyone wanting to experience the natural beauty of the Larian Triangle, offering a unique perspective on Lake Como. The route provides a chance to see both branches of the lake from a single vantage point, and on clear days, you might even spot Monte Rosa in the distance. It's a fantastic way to immerse yourself in the region's stunning landscapes and appreciate its diverse ecosystems.

Monte San Primo Ridge

Highlight • Trail

The crest that leads to Mount San Primo allows you to admire spectacular panoramic views of Lake Como and the Alps. The view of Mount Rosa stands out for its beauty. You have to pay attention to the crest, especially in the winter months: in this last season it is essential to bring at least crampons.

From the 1,435 meters of Bocchetta di Terrabiotta there is a splendid view of the tip of Bellagio and the bifurcation of Lake Como. Its name Terrabiotta (Naked Earth) comes from the Como dialect. The name derives from the fact that the strong winds, which often whip here, make this area almost devoid of grass.

The first summit tour on Lake Como led in perfect weather to the "local mountain" in the Triangolo, Monte San Primo 🔝 The plan was, as usual, to take the second wave of ascent with you, which means to start late in order to meet as few people as possible at the summit. Unfortunately, this plan did not work 😅 …

Yesterday a lesson in humility, and then arrogance.
We were calmly climbing up the vertical from Martina. Beautiful and cool day. We met many people on the way down and everyone was quite equipped. A guy passes us by, followed at a distance by another... the second one, to my surprise, is wearing sneakers with a smooth bottom (I think: …

Beautiful ride even though I think I did it backwards. Going down towards the Martina refuge there is a lot of ice and crampons are essential.

At 1,681 m, Monte San Primo is the highest mountain in the Lariano Triangle, which divides Lake Como into two arms. I went up the northern slope of San Primo in 2018 and thought you were crazy. And I did it again. The climb is steep and strenuous. It took me two hours to do it. The summit is awesome. …
