We climbed on March 6th. The beech forest in its winter glory is a marvel, with a carpet of dry leaves on the ground and tiny patches of snow here and there. The view is stunning!

The region around Trontano, particularly in the Ossola Valley, offers a diverse range of lakes. You can find natural glacial lakes like the tiered Paione Lakes, dramatic landslide-formed lakes such as Lake Antrona, and smaller artificial lakes like Casalavera Lake and Lake Onzo Filippini. Each offers unique scenery and experiences.
Yes, Lake Antrona in the Antrona Valley has a dramatic history. It was formed by a massive landslide in 1642, which submerged an entire village. During dry periods, it's said that the stones of the old submerged houses can still be seen, adding a unique historical dimension to its natural beauty.
Beyond the lakes themselves, you can find stunning viewpoints. View of Lago Maggiore and Lago di Mergozzo from Monte Faiè offers panoramic views of both lakes and the Val Grande. Another excellent spot is View of Lake Maggiore from Monte Todum, which provides an unobstructed view of Lake Maggiore's three arms and the surrounding mountains from 1,283 meters above sea level.
Yes, Casalavera Lake and Lake Onzo Filippini are both noted as family-friendly. While many trails in the Val Grande National Park can be challenging, these artificial lakes often have easier access or are part of less strenuous routes, making them suitable for families or those seeking a gentler walk.
The lakes are often accessed via scenic hiking trails. For example, the Paione Lakes are reached via routes like sections of the Grande Traversata delle Alpi (GTA) and the D10 trail, passing through larch forests and glaciated rock formations. From Lake Antrona, you can also follow a path through the woods to reach the artificial Lake Campliccioli, expanding your exploration options.
The spring and summer months are generally ideal for visiting the alpine lakes. During this time, the trails are more accessible, and natural features like the Sajont waterfall at Lake Antrona are particularly impressive due to higher water flow. The tranquil environment and lush alpine pastures are also at their best.
Absolutely. At Lake Antrona, you can experience the impressive Sajont waterfall, where the stream plunges directly into the lake. A wooden bridge allows visitors to walk directly behind the cascading water, offering a unique and immersive experience. The Paione Lakes also stand out with their unique tiered formation, a result of glacial activity.
