Parco del Medio Olona, Nature reserve in Province of Varese, Italy.

Parco del Medio Olona is a protected area of supra-communal interest in the Province of Varese, covering the territories of Fagnano Olona, Gorla Maggiore, Gorla Minore, Marnate, Olgiate Olona and Solbiate Olona. It follows the Olona and Tenore rivers, and to the east takes in the Gorla Maggiore woods, crossed by the Fontanile di Tradate, while the rural land west of Fagnano Olona is watered by the Tenore.

The park was established on 29 March 2006 as a protected area of supra-communal interest, managed jointly by Fagnano Olona, Gorla Maggiore, Gorla Minore, Marnate, Olgiate Olona and Solbiate Olona in the province of Varese. Its territory was organised around the Olona and Tenore waterways, the Gorla Maggiore woods and the rural land west of Fagnano Olona.

The park links several communities through cycling paths and serves as a gathering space for outdoor activities. These routes pass through varying landscapes where built-up areas give way to open countryside and wooded sections.

You can enter the reserve from multiple points across the surrounding municipalities, allowing flexible exploration. Wear appropriate footwear for mixed terrain and plan your visit during dry conditions for the best experience.

The Gorla Maggiore woods on the eastern side stand out for their dense forest cover and are fed by year-round springs. This section hosts a variety of woodland wildlife that most visitors overlook while passing through.
