Mountain Biking Marian R. Bear Memorial Park

***   Add a review
#306 of 1,003 mountain bike trails in California
#3,833 in the world

Marian R. Bear Memorial Park is located just off the 52 Between I-8 and I-805 in San Diego. It consists of a doubletrack "spine" with several singletrack splits and out&back branches, some of which end at alternate trailheads.
Considering the location, smack in the middle of urban chaos, this park is a surprising and very pleasant find. While there is nothing overly technical, there are a good number of very pleasant singletrack spurs and side trails to be found.

From the trailhead at the east end of the parking area, head east along the main trail, grabbing any marked spurs or singletrack you see. At this time, all side trails are open to bikes as evidenced by the cities' website and trailhead 4X4 post markers. Continue east past Genessee until you reach the 805. This is the turnaround point/park boundary. Beyond the 805 is Miramar which is off limits. Trespassing can result in the loss of your bike, according to literature and reports. Proceed back (grab any spurs you may have missed - they are they best part of this trail system.)

An added perk to this area is the ample shade. This place is just the ticket on a hot summer day. The scenery doesn't hurt, but unfortunately the 52 is always within earshot so there is no escape from the traffic noise without earphones.

    Took my daughter here for her first ride, turned out to be more than beginner. Several sections were loose river rock where she didn't stand a chance and had to walk. Even I had trouble maintaining speed and a line. Despite that, the overall was great, with the side trails being clear of those issues, wonderful shade, and an overall beautiful experience.

    Basic doubletrack trail with many singletrack trails along side and into the surrounding canyon. Mostly flat non-technical miles.

    Very fun trail, plenty of creek crossings and death cookie sections. Very doable for beginers who want some adrenaline. Several fun side trails. Plan on getting muddy/wet in the flooded areas duing winter. Overall, great spot to checkout. It can also be linked to the rose canyon open space trail if you check out the route on google earth.

    A nice easy trail with some options to ride into other canyons close by. Flat and meandering trail that sees a lot of multi-use. Fun for night rides.
