Tri-peaks is a gigantic pile of huge rocks but basically there are three large boulders, surveying everything in sight - from Thousand Oaks, Camarillo and beyond to the Channel Islands and Malibu. They're pretty close together, and their porous surface makes for great climbing.
There are a number of caves and crevasses between them, many large enough to enter and explore. There are also spectacular views into the valleys and canyons to the west. The trail is a short spur off the Mishe Mokwa where is meets the Back bone trail. Tri-peaks is an area well worth visiting to see the caves and other rock formation
There are two forks of the Tripeaks Trail that meet the Chamberlain Trail (Back Bone trail). Both forks are extremely rocky but not overly steep. The eastern fork provides the shortest path from Circle X Ranch, but is somewhat overgrown with plenty of Spanish Bayonets. The southern fork is much wider. The Tri-Peaks Trail was significantly more rugged and overgrown than the Mishe Mokwa or Backbone Trails. Whereas most of the trail up to this point is fairly wide, mostly level footpaths, this was overgrown, washed out, and in need of a bit of maintenance.
If you look a bit southwest of the face, you'll see a small steel pole sticking up out of the mountain. It's a USGS marker, and the way to the proper trail. A little scrambling later, and you'll be face to face with the Tri-Peaks. The trail climbs up to base of the summit block on the south western side.
The summit of Tri-peaks about 400 yards east of the junction of the southern and eastern forks. There are places where it may be a little hard to follow on the bare rock, but it travels around the peak counterclockwise, mostly against a rock face, often steep down and a little loose.
From the Circle X Ranch ranger station (the closest bathroom to the trailhead), drive up Yerba Buena Road another mile and turn left into the Sandstone Peak trailhead parking lot.
Milage from the Sandstone trail head

3.0 miles Base of the summit block
To gain the summit proper it is necessary to do some class 3 or slightly harder climbing. Circle around the main block counter clock wise, working your way down until you can get between the two main blocks. Going between the block leads to a not so steep outside corner that has many great holds and leads directly to the top.
