15 placesWhere to go when you want the Milky Way instead of a glow on the horizon. Fifteen places with genuinely dark skies, from the least light-polluted park in the lower 48 to a 9,200-foot volcano above the cloud layer, an Appalachian ridge with a 360-degree horizon, and an Alaskan hot spring under the aurora.
21 placesAlpine lakes, fourteeners, and golden aspen along the spine of the West. The Rockies at their most iconic: the Maroon Bells mirrored in their lake, the Tetons rising straight off the valley floor, Glacier's Going-to-the-Sun Road, the red spires of the Garden of the Gods, and Idaho's serrated Sawtooths over Redfish Lake. From Colorado's San Juans to the Wyoming Tetons, Montana's Glacier, and the Idaho high country, with high passes and old mining towns in between.
9 placesNowhere else packs this much sandstone into one state. The Mighty 5 national parks, a twelve-mile slot canyon you walk single file, the first Dark Sky Park ever certified, and a river hike between thousand-foot walls. Nine places, from drive-up overlooks to corridors ten inches wide.
22 placesStep out of the daylight into another world: the longest cave on the planet in Kentucky, a desert chamber big enough to swallow a stadium in New Mexico, an underground waterfall in Tennessee, and a living crystal cavern in Arizona. Some you walk, some you ride a boat through, and one you crawl with a headlamp. America's great caves and caverns, from the national parks to the lantern-lit show caves.
