In the north-east of the Province we find the Apuan Alps Park with paths marked by the Club Alpino Italiano. Its proximity to the Tyrrhenian coast, parallel to the mountain ridge and about 15 km away as the crow flies, creates a great variety of environments according to geology, altitude and exposition, the latter being important as it influences the resistance or not of coats of snow. The Apuans are famous first of all for their marble, which was quarried in antiquity for statuary use and today is exported in the whole world. Karst phenomena have given rise to some spectacular "monuments", such as the Antro del Corchia, a cave that has been equipped and lighted for guided tours along several itineraries.
Such a rough environment required a great effort for the local populations to obtain a revenue from their traditional productions, an effort that is well documented in the "Museo del Lavoro e delle Tradizioni Popolari della Versilia Storica" of Seravezza.
