Directions from Broadway: Traveling north passed the University turn left on to Mapleton Avenue. The trailhead lies approximately seven blocks west of Broadway. While parts of this hike are dog friendly, dogs are not allowed on Lions lair section of the trail.

Usually do the Mt Sanitas trail up & down, but today I tried out the Lion's Lair trail. Wanted to check out the suitability for when my grandsons visit. Good trail, about 4 miles rt with about 820' vertical gain from the parking at the hairpin turn. A milder, less crowded alternative to the "usual" south ridge.

Short but somewhat steep hike (for a Jersey hiker not used to the altitude). The hike down was relatively easy. Beautiful views. I hiked at 7 am on a Saturday and it was busy but not crowded.

Loved it. I'm not in the best shape, so this was challenging for me; but there are lots of places to stop, catch your breath and take in incredible views of Boulder to the west and the Rockies to the east.

Beautiful views, challenging but still very fun! My dog loved it too!

A classic!
