Campo dei Fiori Regional Park (Parco Regionale Campo dei Fiori) is a protected natural area in northern Italy's Lombardy region. Established in 1984 and expanded in 2009, the park spans approximately 6,300 hectares and encompasses the Campo dei Fiori and Monte Martica massifs in the Varese Prealps. It is situated between the Valganna and Valcuvia valleys and the city of Varese and extends across 17 municipalities.
The park is home to various flora and fauna. Woodlands of chestnut and beech trees and rare wild orchids provide habitat for numerous species, including deer, foxes, and a diverse array of birds. The area is also geologically significant, featuring over 130 caves with a combined length of around 30 kilometres. Campo dei Fiori hosts six designated nature reserves, such as Lake Ganna and the bogs of Carecc and Pau Majur, offering vital ecosystems for conservation and research. The park is part of the EU's Natura 2000 network, underlining its importance in European biodiversity protection efforts. The Sacro Monte di Varese is a UNESCO World Heritage Site, which adds cultural significance to the natural setting.
Beyond its ecological and recreational value, Campo dei Fiori Regional Park is proactive in environmental stewardship and sustainable land management. Approximately 20% of the park is managed actively for user engagement and conservation. The park has considerable experience with participatory approaches, promoting citizen involvement in environmental protection and sustainable resource use. It also has the infrastructure and capacity to host secondees, supporting collaborative projects and international exchanges.
