Mountain Lion Trail: Hike Review

You are currently viewing Mountain Lion Trail: Hike Review

The Mountain Lion Trail in Colorado’s Golden Gate Canyon State Park is one of the premier trails within the entire park. At 6.7 miles in length and designated “Difficult” by Colorado Parks and Wildlife, the Mountain Lion Trail is a fairly challenging loop hike, but not overly intense. Given the trail’s proximity to the Denver metro, this is a great day hike or trail run option for a weekend excursion.

Indeed, the diverse terrain of the Mountain Lion Trail is stunningly beautiful, with expansive views of nearby foothills, vistas of Front Range mountains, dense forest, and peaceful Deer Creek crossings. You can also opt to tack on a side trip to the summit of Windy Peak if you’re inclined. With or without Windy Peak, we think the Mountain Lion Trail is a true gem and one not to be missed.

Route Instructions

  • Step 1 - Park at the Nott Creek Parking Area, which is down a service road adjacent to the Red Barn Group Picnic Area. If you haven’t paid the park entrance fee ($9.00), there is a self-pay station at the entrance of the service road.
  • Step 2 - Beginning the trail in a counter-clockwise direction, start on the Mountain Lion Trail and pass the parking area restrooms. The trail will start to slightly incline. Metal stakes with a mountain lion paw icon clearly mark the trail along the route, indicating you’re on the right track.
  • Step 3 - You’ll reach a dirt service road in about .5 miles. Bear slightly to the right on this road to stay on the Mountain Lion Trail. Blue Mountain will become visible directly ahead.
  • Step 4 - The Mountain Lion Trail splits off of the service road, with signs indicating distances to the Quarry Site (.9 miles) and Deer Creek Campsites (1.4 miles). Bear slightly right to stay on the Mountain Lion Trail.
  • Step 5 - You’ll eventually reach a Deer Creek footbridge crossing. Signage will indicate distance to the Quarry Site (.6 miles to the right) and Windy Peak (2.8 miles to the left). Turn left in the direction of Windy Peak.
  • Step 6 - As the trail continues into more dense forest, you’ll pass some backcountry campsites and a shelter, then reach the junction with the Burro Trail. Make sure to follow the Mountain Lion Trail towards Windy Peak (2.2 miles from this point).
  • Step 7 - You’ll cross Deer Creek a number of times and continue to increase elevation gain as you head up the trail. As you exit the dense forest, you’ll soon see a vista of Front Range mountains, including Mount Evans and Mount Bierstadt.
  • Step 8 - The trail will start to head downhill, towards the Forgotten Valley. You’ll reach a junction with the Buffalo Trail, but continue to Forgotten Valley (which is .2 miles from this point).
  • Step 9 - Once in the Forgotten Valley, you’ll reach a pond and the Tallman Ranch, which was a homestead in the 19th century. The ranch is now preserved as a historic property.
  • Step 10 - Continue along the Mountain Lion Trail, back towards Nott Creek. You’ll eventually reach the junction with the City Lights Ridge Trail. A side excursion here is about one-mile, round trip.
  • Step 11 - Following the Mountain Lion Trail further along, you’ll again pass intersections with the Burro Trail. Be sure to continue along the Mountain Lion Trail to head back to the trailhead.
  • Step 12 - As you hike the remaining portion of the Mountain Lion Trail, you’ll see exceptional views of evergreen forested foothills.
  • Step 13 - End the hike back at the Nott Creek Parking Area. Enjoy the rest of the day and reminisce on the great hike you just accomplished!

Recommended books

If you intend to visit more Colorado state parks beyond Golden Gate Canyon, “Colorado State Parks: A Complete Recreation Guide,” though a bit dated, does a nice job providing general overviews of the parks. In addition, we recommend picking up a few naturalist guides for general awareness of the area. An easy to use field guide for plants and birds will help identify species and further add to the enjoyment of your outdoors experience.
