In 1965, Ugo Pompanin decided to abandon his job at a butcher shop and pursue a labor of love in the mountains. The result is this hikers’ castle, perched at 9,029 feet on Mt. Lagazuoi. Best plan: Reach it on night two of a north-to-south traverse of the 75-mile Alta Via 1. On the eight- or nine-day trip, you’ll cross sheer cliffs with the help of via ferrata, trace lush valleys choked with poppies, and wake to Dolomites views like this one.
