Gola della Rossa e di Frasassi Regional Park, established in September 1997, is the largest regional protected area in the Marches: it also includes the hypogeal complex of Frasassi Caves. A journey across the Park is "a journey in the heart of the Marches" at the discovery of historical-artistic treasures concealed by landscapes rich in charm and harmony and surrounded by an uncontaminated and luxuriant nature.
