Prades Mountains

A high-speed train between Barcelona and Alicante stops in Tarragona, the closest major tourist destination to the Prades. The coastal resort town has hotels, tour operators, and car rental service, and buses into the mountains. The Prades Mountains, however, do not lend themselves to independent exploration via public buses, though adventurous types with some Spanish (or Catalan) skills and plenty of time can certainly do it. It's much easier to either rent a car or book a tour.
