This trail may be the prettiest trail in Ventura County, and that's saying a lot! It follows a rocky ridgeline with views to the south of Oak Park and the Lindero/Kanan area, and views to the north of Albertson Mtwy with Wood Ranch and Simi Valley beyond. But the real beauty is in the sandstone formations and rocky landscape.
It starts at the Oakbrook Vista Trail in the Oakbrook Regional Park and and connects to the Simi Peak Trail a few hundred yards before the peak. The distance one way is 1.7 miles with a cumulative climb of about 900 feet. In addition, the trail starts 1.3 miles from parking at the cache "Oakbrook Trailhead" (GC1JJTK, http://www.geocaching.com/seek/cache_details.aspx?guid=a327dad6-a464-4177-87d7-17c475e19fc2 ), with about 650 feet of climbing. The trail is mostly easy to follow except for a steep section in the middle that goes through a field of large boulders.
