The whole of the Alpi DI Suisi is connected by wonderful bus routes. AT the main bus station in Castelrotto, you will find schedules for all the towns that are on the routes, with great LED signs at the stops that count down in minutes how long until the bus arrives. You can travel all over this region for a reasonable price on modern comfortable buses. The whole Alpi di Suisi meadow area is essentially car free anyway, you can only take a car if you are staying in one of the area hotels. They do have what's called a combi card, which gives you a 3 or 6 day pass and includes the shuttles, buses and cable car.
During the opening hours of the cable car up to Alpe di Siusi (Seiser Alm Bahn) from 09:00 to 17:00 you can not drive up by car!
Before and after the parking ticket is about the same amount as a ticket for one person with the cable car.
About 13.50 Euro
