Description

The trailhead is located at the fork where Mt Lowe Road, Middle Sam Merrill Trail, and the trail to Inspiration Point are. From this intersection, Idlehour Trail goes east and down. This is some nice singletrack and an alternative to the other trails around. There is a nice climb out from Idlehour Campground, and the trail can get thin and overgrown but it is rideable. Use the Mt. Wilson Toll Road, through Henninger Flats, to exit onto Pinecrest Drive in Altadena.

Make sure you have enough energy, water, and daylight, to get back up the exit climb (some sections can be hike-a-bike).

The climb from the campground up to Mt. Wilson Toll Rd is somewhat steep (and slippery when littered with damp leaves :) )
