Serrano Canyon is quite an attractive destination in Pt Mugu State Park in the Santa Monica Mountains. So beautiful in there. It is quickest to get to Serrano Canyon from Malibu but trekkers, runners and cyclists certainly can make their way from the Newbury Park side at Satwiwa/Rancho Sierra Vista.
To get down to Serrano Canyon from the Conejo Valley side, you must meander your way down the steep Sycamore Canyon Fire Road seen above. Have fun and don't think about the challenge of making your way back up this hill later in the day, when the sun is beating down on you! haha
Continue on down Sycamore Canyon Road, pass through the Danielson Multi-Use area, the National Park Service house and the old barn-like structure seen above. You can actually get to Serrano via the Blue Canyon Trail entrance point just east of the Danielson Multi-Use area.
Onward down Sycamore Canyon, one of my favorite sites is this porta-a-john, situated in a serene setting next to several picnic benches under a beautiful tree on the right.
A little farther down is the Serrano Canyon Trail trailhead. Two or three miles into this trail and you'll be in Serrano Canyon. Warning...this trail has had some fairly well overgrown sections in my times in there, so definitely be aware and consider long pants. I ran through there and survived in shorts but the poison oak on the sides of the trail were nervewracking enough to make me consider turning back.
There are several ways out of Serrano Canyon but my choice was to follow a trail that loops back around to Sycamore Canyon again, about a mile or so north of the entry point and south of the Danielson Multi-Use area. The map below show the loop above coming from the Malibu side.
Truly a beautiful hike! Check it out if you can!
