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.

Check in advance, if the bike path is snow free. There is only this way to go over Loveland Pass. the street from the ski resort to the pass is well maintained, but not the bike path. The old Highway and the bike path are great - when there is now snow. Pictures date from 19 May 2024.

Just off the winding road, there is space for one or two cars to enjoy the great view towards Georgetown, a former mining town that was founded in 1859 and sits in the valley.

Georgetown was founded in 1859 during the Colorado Gold Rush by George and David Griffith, two prospectors from Kentucky. After 1864, gold and silver ore was mined in countless mines around Georgetown. The town was not a mining camp, but a center for the ore miners and prospectors. Today, the town has a really nice atmosphere and you can still take a ride with the old steam train. There is also a very nice brewery at the north end of the town
