"Mount Sanitas is known to have the occasional mountain lion visit, along with coyotes, foxes, and plenty of mule deer (aka lion food). That is probably the reason why Boulder’s newest—and arguably most awesome—trail is named “Lion’s Lair.” Completed in the spring of 2015, the route to Lion’s Lair starts to the southwest of the Centennial Trailhead on a trail that parallels Sunshine Canyon Road, heading up the canyon."

The rock formations were amazing--great for bouldering/climbing. This was mostly shadded in the morning. Intermediate/Difficult hike and the trail, in some places, is unmarked. Great views!

The first time I hiked this trail was last fall. I did the loop and it took me almost four hours up the easy side and down the difficult side. I hiked the trail last month in half that time going the reverse route. In the process I strained a tendon in my ankle. A comon injury as a result from hiking up steep hills. Trail running is the way I like to approach hiking trails. For the avid trail runner it would be easier to hike the steep side and run down back side or easy side. That is the approach I will take in the future. The steep side is riddled with many boulders. I have been running for over 30 years and trail running about 15 years.

This trail is a easy to moderate hike, getting more difficult as the trail gets into higher elevations. Great views from the top, higher than the Flatirons! A good quick hike
