The global shift toward flow mountain-bike trails—less pedaling, more fun—has sparked a new wave of outfitted adventures. This July, Alaska's Alyeska Resort will open three lift-accessed, 2,000-vertical-foot singletrack downhill trails, including a mellower roller-coaster-like option for beginners and enough obstacles to scare experts. Passes from $30 per day; alyeskaresort.com. Idaho Smoky Mountain Lodge's new 160-acre Bike Ranch is mountain-bike heaven, complete with pump tracks, a BMX course, and cross-country trails. On a three-day course with EpicQuest, learn to jump higher, ride ladders, and negotiate teeter-totters. From $1,699 for three days; June-October; epicquest.com. Yukon-based Boréale Mountain Biking's four-day Summer Solstice Package puts guests on Whitehorse's 400-plus miles of trails, with one ride taking place under the midnight sun. Crash in a solar-powered yurt camp with a bicycle-powered blender for margaritas. US$1,209; June 27–July 1; borealebiking.ca.
