First hiked here just over ten years ago to the day. Sandstone (twice), Mugu, Boney Peak, Inspiration Point, and the Tri-Peaks.
The word has gotten out and trails are crawling with people on the weekends. The Sandstone Peak trail had (as of 1/1/18) four dog waste bags abandoned alongside it, and the number of people going up with their canines beggared belief. Not much of a "natural" experience.
Sandstone, Triunfo Lookout, Ladyface, Saddle Peak East, Calabasas.
I hiked the Mishe Mokwa trail and visited the summit of Sandstone Peak on March 5, 2016, through the fog and mist. No views. Will need to return on a clear day.
I've hiked a few trails from the Santa Clarita side, and a few from the Malibu area. Lots to explore here!
Have hiked the Pt. Mugu Park trails, at the westernmost end of the Santa Monica Mtns. Have also been to the Satwiwa area, Paramount Ranch, and driven the Mulholland Hwy. Hope to hike more of this area!
Sandstone Peak baby!
