The Monarch Pass climb from the west, starting in Sargents is a classic and scenic road biking ascent on US Highway 50. Over approximately 10 to 11.5 miles, you'll climb around 2,750 to 2,850 feet at a consistent average gradient between 5% and 6%, winding your way up into the Sawatch Range. As the road is often cut into the mountainside, you'll ride through forested areas with glimpses down to Agate Creek below, and the scenery becomes increasingly open with expansive mountain views as you near the 11,312-foot summit. Be aware that while the road is good, it can have moderate traffic, and you'll be dealing with significant altitude as you climb higher.
