Nice, quick trail. Well marked, patrolled, and maintained. Not much parking at the trail head. The trail is narrow and had a lot of traffic, so we moved aside several times for the hardcore jogging crowd. The peak at the top was clustered with people (Sunday around noon). That said, gorgeous, if not typical, views from the front range over Boulder. As nice as it was, we will probably try every other trail in the area before we go back to this one.

Fun hike with a few sections of snow on the trail but nothing to deter you from giving this trail a try!

Nice hike. Did not need micro spikes even though there was a bit of snowpack. Awesome view at Sanitas!

Very beautiful views on this moderate trail. A great running trail, and lots of nice places to stop and have a picnic.

Relatively easy out and back on a nicely kept trail. Gets excellent afternoon light.

Trail was in good shape. Elevation was gradual with switchbacks. I got there around 10am on a Saturday and there was little traffic on the trail. By the time I was on my return trip, the traffic had increased drastically. Great hike overall with some good views.

Excellent trail with spectacular views of the Indian Peaks as you gain elevation
Terminated at Sanitas Mountain where you then have 3 options: return back same way, or choose 2 other trails back down.
Please observe the no dogs allowed restrictions

Little traffic, trail in great shape. Very gradual incline and not very rocky. A lot of switchbacks. Views of the snowcapped mountains west and Boulder east at different points along the way. Excellent for trail running without a ton of elevation.

Nice smooth trail with switchbacks most of the way. Beautiful scenario of mountains and forest. Much better on the knees and joints.

Rated easy by some but I give it a moderate to difficult if you do a large loop as I did and return via the East Ridge Trail to avoid the hoards on the Sanitas Valley Trail. I rate it easy-moderate-difficult in places depending on which descent you choose. I began at the Centennial Trailhead and walked up Sunshine Cyn. Trail crossing the Sunshine Cyn Rd. to the Lion's Lair Trailhead. Adds a mile one way. I plan to do it again but to go out and back and avoid BOTH the dodgy East Ridge and the over-crowded Sanitas Valley Trail descents. A well-cut and maintained trail but I did see the ever-present dog poo bags, etc. I recommend spring for viewing wildflowers. Fun with great views.
