Why do we love Jackson, Wyoming? It's not the celebs playing dress-up in cowboy hats and Carhartts. But we know one new reason: cable-assisted climbing in the Tetons. Starting this month, rookie climbers can visit Wyoming's higher elevations without a chalk bag, thanks to Jackson Hole Mountain Resort's new European-style via ferrata climbing system. Once approved by the U.S. Forest Service, Jackson's Iron Road, a network of fixed steel cables on the upper reaches of the ski area's 10,450-foot Rendezvous Mountain, will be just the second via ferrata to open west of the Mississippi. Clipped into the bolted cables with a harness and a couple of tethers and carabiners, ferrata climbers pull themselves up a series of cliff bands on 9,200-foot Casper Bowl (guided climbs from $160; jacksonhole.com). The resort plans to expand the system into a network of 12 routes stretching to Rendezvous's summit within two years. Oh, and one more reason to love this place: August 16 kicks off the first Jackson Hole Music Festival, a two-day bash headlined by Wilco and the Black Crowes (from $73; jacksonholemusicfestival).
