When the Rosa Alpina resort reopens, in December, as Aman Resorts’ first hotel in the Dolomites, expect major changes—and not just snazzy new interiors from designer Jean-Michel Gathy.

Owner Hugo Pizzinini, whose family has run the hotel in only the summer and winter since 1939, is changing things up. “We want to stay open almost year-round, and go from the monoculture of just skiing to something else,” he says, planning to market summertime frolics and fall hikes as much as idyllic ski days.
