1600 feet gain
From Highway 101/Ventura Freeway in Newbury Park, exit on Wendy Drive. Drive 2.5 miles south to Lynn Road and turn right. Continue a mile or so, then just past Reino road turn left into Rancho Sierra Vista/Satwiwa Park on the left side of the road.
This hike includes some breathtaking up-close views of the shear rock faces of Boney mountain. Follow the Satwiwa Loop trail west past a pretty pond, then bear right at a quarter mile and head toward the Boney Mountain Trail across the open grassland. Go left on the Boney mountain trail and follow above sycamore canyon to where it drops into the base of the canyon to a lovely waterfall a few hundred yards past the Hidden Valley Trail junction. Backtrack to the Boney Mountain trail and continue upwards towards the Danielson Monument, bearing left at a trail marker pointing towards the monument. From the monument/old cabin site, head south for about 1 mile to a stunning overlook of Boney Mountain, which is our turn-around point. You will see a bench like rock on the trail with an unforgettable view of the rock faces. Note that this last section of trail is very steep and it is not maintained, so use caution. Some hikers may want to continue on to the tri-peaks area.
