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.

Juniper Pass is a fantastic ascent on Highway 103, taking you high into the Front Range of the Rockies. Over approximately 14.7 to 14.8 miles, you'll gain around 3,400 to 3,500 feet at a steady average gradient of about 4.3-4.6%, rarely feeling overly steep as you wind your way up through thick forests. The scenery is consistently beautiful, with trees lining the road for much of the climb, gradually giving way to more open vistas and stunning views of the surrounding peaks as you approach the 11,130-foot Juniper Pass summit, where the air is thin but the high-altitude views are well worth the effort.

Starting from the historic mining town of Georgetown, the Guanella Pass climb offers you a spectacular journey through dense forests opening into breathtaking high-alpine tundra with views of towering peaks like Mount Bierstadt. You'll ascend approximately 10.5-11 miles, gaining over 3,100ft to reach the lofty 11,669ft summit. Be prepared for a challenging profile: after a steep initial section of 6-7% on average, the gradient eases through the middle before a very tough final 2.3 miles featuring steep switchbacks averaging over 7% with ramps hitting 10-12% or more, made significantly harder by the extreme altitude. The pass is seasonally closed so be sure to check before attempting this climb.
