Parco delle Groane e della Brughiera Briantea, Nature reserve near Milan, Italy.

Parco delle Groane e della Brughiera Briantea is a protected regional park of 8,249 hectares on the high Lombard plain northwest of Milan, established in 1976. It spans 28 municipalities across the provinces of Milan, Monza and Brianza, and Como, at elevations between 160 and 300 metres. Its terrain is a clayey plateau with ferretto soil, covered by oak woods, Scots pine stands and heathland, with a shallow stream running through the woods.

The protected area was established in 1976 and underwent major expansion in 2017 when it merged with Brughiera Briantea Park and Fontana del Guercio Natural Reserve. This consolidation created the present size and significance of the reserve.

The name "Groane" comes from the local historical term for the heathlands. The park also holds sites of industrial archaeology alongside historical-artistic assets, and WWF volunteers run the Il Caloggio oasis, where environmental education activities take place.

The area is crisscrossed by a network of around 50 kilometers of cycling and walking trails connecting different sections and offering various difficulty levels. The main visitor center Centro Parco Polveriera in Solaro serves as a good starting point to plan your routes through the park.

The heathlands are a temporary ecosystem: when a wood is cleared by felling, grazing or fire, heather and other acid-soil plants colonise the ground, then birches, aspens and Scots pines follow, and within a few decades the heath turns into pinewood. The Scots pine stands, best kept near Cesate, were planted under Austrian rule in the 18th century.
