Marmot Passage Trail

From the four way intersection with the Border Line Trail, Bugling Elk Trail, and Staunton Ranch Trail, follow signage to Marmot Passage Trail. The first .5 miles is steep uphill through a heavily wooded area, but the trail levels out after passing the intersection with Scout Line Trail. After reaching the summit (.75 miles), descend onto a more sparsely wooded western-facing ridge that offers great views. The next 1.75 miles is an awesome downhill section into Twin Elk Lake. It is rocky, and you'll encounter a fair number of switchbacks, but as long as you're careful this descent can be very fun. The trail terminates at Twin Elk Lake.

New trails are being put in and existing ones are being changed at a rapid rate and are sometimes not reflected in the park maps. For up to date trail directions and information about new construction ask the park rangers, they are extraordinarily friendly and willing to help (seriously the most friendly park staff I've ever met by far).

Trailhead parking is abundant on weekdays, but will fill up before 9 am on summer weekends.
