Call it the Bike Rush: after 10 years of connecting a mashup of mining, animal, and recreational paths, the neighboring cities of Whitehorse and Carcross (50 miles south on the Klondike Highway) have created a singletrack network to rival Vancouver’s North Shore. A seasonal crew maintains more than 500 miles of trails, from flowing beauties along the banks of the Yukon River to bermed, bridged, and ramped epics. In Carcross, the epicenter is Montana Mountain, an old silver mine turned mountain-bike park with 33 miles of all-mountain and downhill trails. Rent a Specialized Camber at Cadence Cycle in Whitehorse (US $55 per day), enter the trail network downtown, and choose your own adventure in the wide-open valley. Bonus: pedal under the midnight sun with Boreale Biking, which offers a five-day summer solstice trip, where guests stay in plush yurts minutes from downtown (US $1,195).
