Monte San Primo with its 1682 meters above sea level is one of the favorite destinations for hikers. The mountain of the Pre-Alps Comasche is one of the highest peaks of the Larian triangle, with a 360-degree observation point spanning from Lake Como to much of the Alpine arc.
On beautiful clear days and clear skies you can also see the Apennines to the south.
The river Lambro was born in the mountain group of San Primo, on the border with the Prealpine line which on one side heads towards the Seveso springs at Cavallasca and on the other leads to Gallarate.
From the Rancio Plan, one of the easiest paths to the summit of Monte San Primo starts; you get there via the Ghisallo pass and is equipped with car parking and ski lifts.
We find a flora rich in woods on the slopes of the mountain, which slopes inexorably into grassy expanses proceeding towards the top.
There are numerous species of flowers including protected ones such as orchids and gentians. The fauna instead is composed of small animals with an abundant population of wild boars, vipers, hedgehogs, hawks, buzzards and other birds of prey.
In 1957 the ski resort of San Primo was born and in a few years three ski lifts were built to service about 12 km giving way to exploit them, given the convenient location, both from Brianza and Como, Milan and Lecco.
In the nineties a judicial cause was opened between the operators of the plants and the Comunità Montana Triangolo Lariano to establish the ownership of the land on which the structures were built. The renovation work of the plant was blocked by making the ski resort lose the most popular slopes with a large number of tourists. The plant was blocked indefinitely until 2010 when the mountain community was recognized ownership of the ski resort that was reopened only on February 4, 2012.
