Situated along the San Juan Mountains, this railroad town offers a pleasant escape from the Southwest’s blistering summer temperatures. And there’s plenty to do. Ride the Durango & Silverton Narrow Gauge Railroad north to the historic mining community of Silverton or raft the Lower Animas River through Durango. If you want to pick up the speed, head to the greened ski slopes of nearby Purgatory, where you can zipline, race down Alpine slides, and mountain bike. In town, shop the boutiques and dine at upscale restaurants and five breweries.
