The Trails Illustrated Map #105 – Tarryall Mts. / Kenosha Pass would be very helpful in navigating to the trailhead.
FROM THE NORTH (DENVER):
Head west on US 285 passing over Kenosha Pass. Just over 4 miles west of the Pass turn south (left) on Park County 77 in the small community of Jefferson. Continue south on 77 until you come to the Tarryall Reservoir. Just south of the reservoir, turn right onto Forest Service Road (FSR) 23.
FROM THE SOUTH (COLORADO SPRINGS):
Head west on US 24 to the small community of Lake George. Shortly after crossing a young South Platte River, turn north (right) on Park County 77. Continue north on 77 until you come to the Tarryall Reservoir. Just south of the reservoir, turn left onto Forest Service Road (FSR) 23.
FSR 23 is passable to most vehicles although a high clearance vehicle would be best. After a few miles you will veer right onto FSR 146. Follow FSR 146 pass the south side of Eagle Rock. You will come to a ninety degree turn with a left turn that will leave Pike National Forest. This is the trailhead for the north ridge route. Continue straight for about a half mile to a faint road on the right that appears to head around Eagle Rock. Turn right and park here. This is the trailhead for the southwest ridge route.
The access roads may not be passable in winter or after a heavy spring snow – check with the Forest Service
