Loveland Pass from Keystone is a fantastic high-altitude road biking challenge on US Highway 6, taking you over the Continental Divide. Starting around 9,200 feet at Keystone, you'll ascend approximately 8.5 to 11.5 miles, gaining about 2,600 to 3,000 feet to reach the 11,990-foot summit, with a steady average gradient typically in the 5.4-5.9% range. As you climb, you'll pass the Arapahoe Basin ski area and gradually transition into beautiful alpine meadows and forests before the final switchbacks above treeline offer dramatic views down to I-70 and expansive mountain vistas from the top of the pass. Be prepared for the significant altitude and potentially rapid weather changes at this elevation.
