The excursion lasts approx. 4.5 hours (elevation gain: 640 m. upward, 460 m. downward). Let's hike beyond the clefts of the Isorno River. First through broad-leaved woodlands and beechwoods and then through the silver fir forest, the core of the Onsernone Reserve. Here, the forest is dominated by big trees, maze of trees of different ages, standing and lying dead trees that decompose slowly and new trees that grow in the space left. In some areas, the forest is dense and shady, whereas in others it is open and bright. Natural evolution is at a very advanced stage, the presence of silver fir dates back 8000 years. In May, the flowering rhododendron (alpenrose) under the dark silver fir is particularly beautiful and the magnificent fern- and moss-covered clefts are outstanding. Different types of mushrooms, lichens and mosses are found on trees and rocks. The black woodpecker shows up from time to time. In Comologno, the Visitor Center is waiting for you.

The enhancement project of the Locarnese Forest Reserves was coordinated by the Locarnese National Park Project along with the expert advice of R. Buffi and the important support of the Canton Ticino Forest Department. The Onsernone Forest Reserve offers a 10 km network of paths classified as mountain paths.
