This is an unusually smooth and well-graded trail. It is much more runnable than every other trail around Mt. Sanitas, and good loops can be formed if you use Sunshine Canyon Drive to connect to Sunshine Canyon Trail
The trail was completed in the fall of 2014 and is a great addition to the area. Starting from the small parking area, take gentle switchbacks through the ponderosa forest. The grade is never steep, and at least for now, the surface is impeccably smooth. The corners and water crossings show off just how well this trail was constructed.
As you ascend, the views get better and better. Be sure to turn around and enjoy the high peaks in the distance. From the top, all of Boulder is laid out in front of you. Return the way you came, or make a long loop by going down the Sanitas Valley Trail
or the Mount Sanitas Trail
, then follow the Sunshine Canyon Trail
back towards the beginning of this trail.
It's a shame this trailhead does not connect to Sunshine Canyon Trail
(there's private property in the way), but maybe someday the county will get an easement to connect them?
The trail name is no accident - this is one of the most frequent areas to spot mountain lions. The trails are closed a few times a year after a lion has killed a deer. You would have to be very lucky to see one... but be aware they're out there!
