Tremalzo is an area of high naturalistic interest and a good starting point for walks and hikes with wonderful views over Valle di Ledro, Lake Garda and the surrounding mountains.

In the 19th century, Tremalzo has come to the attention of botanists all over Europe. Here there are 21 endemic species, flower and plants which are not to be found anywhere else. In Spring and Autumn, migratory birds fly over Tremalzo.

The Alpine meadows of Tremalzo used to serve three of the villages of Valle di Ledro. Malga Bezzecca and Malga Tiarno di Sopra are still in function. Malga Tiarno di Sotto has been transformed into "Monsignor Ferrari Visitors Centre", a place to learn more about the natural environment of Tremalzo.

During the Winter Tremalzo is covered in snow and offers many possibilities for Alpine skiing and snowshoeing.
 

The Visitor Center and the educational area "Monsignor Mario Ferrari" are open every day (except Monday) from July 1st to September 29th, from 10:30 am to 1:00 pm.

During the opening period, it will also be possible to visit the temporary exhibition "Montagne tropicali" – Biodiversity and High-Altitude Environments between the Tropic of Cancer and the Tropic of Capricorn.
