Mosquito Pass, at an elevation of 13,185 feet, is one of the highest mountain passes in Colorado and its access roads are rich in mining heritage. Constructed in the late 1870s, the Mosquito Pass Road was popular despite its treacherous terrain because it was and still is the shortest route between Fairplay and Leadville. A driving tour brochure is available for the Mosquito Pass Road to guide you on your journey. The Mosquito Pass Road is extremely rough once it passes the North London Mill and should only be traversed by high clearance, 4WD vehicles or on foot. From Fairplay, follow Colorado Highway 9 north for 4 1/5 miles to County Road 12 (Mosquito Pass Road) and turn left. The tour begins quickly after turning off Highway 9.
