Hike Las Trampas regional park

Greetings all My next hike will be at Las Trampas Regional Park.
Hike will be 3.5 to 4 miles long with 500 + feet elevation gain loss.
All elevation is done at the start and all elevation loss at the end.
Great Vistas another bring your camera hike. To get there take the 680 to
Crow Canyon Rd go west to Bollinger Canyon Rd. Turn Right at
Bollinger Canyon and take it to the very end. The staging area is at
the very end and is NOT the first large parking lot you see. Trail head is
there. Could be chilly on the ridge bring a jacket. Hope to see you there
