Dog-Friendly Activities in Castelvecchio Calvisio, IT

Ferrovia dei Parchi, also known as the Italian Trans-Siberian, is a 12-hour pet-friendly round-trip every Sunday from Sulmona, IT to Isernia, IT near Naples. The train climbs more than 4,000 feet into the Maiella mountains, stopping at five main cities for around an hour to allow you and your pooch to stretch your legs along the way. Small dogs are welcome, but must be leashed and cannot occupy seats or be in the central corridor.
