Double Peak Hike is a 4.3 mile lightly trafficked out and back trail located near Altadena, CA that features beautiful wild flowers and is rated as moderate. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible from March until October.
Park .2 miles above red box (only a few spaces). Trail is across the street zigzagging up into the forest. Watch sliding soil at first. Steep climb all the way up (a service road is off to the west at various points). When you dump out onto the road, you can either go right to grab Mt. Disappointment (road up to an old military base) or go left for a slightly longer climb to Mt. San Juan (which has the USGS plate at the peak). You can continue over to Mt. Lowe and exit back onto the Mt. Wilson road for a longer, three-peak hike. If you do that option, head back to the main road (thru the tunnel) and just grab a ride down with someone nice back to your car!
