Mountain Biking Lake Del Valle

****   Add a review
#361 of 1,003 mountain bike trails in California
#4,350 in the world

My personal favorite trail would be on the road up to the
camping/swimming/boat launch area. If you stop on top of the tallest point,
there is a gate that is a ride road. If you go down some, there is a trail leading
off to the left down the hill, it is pretty steep, then it leads to a fire road that will
eventually go through an opening in a fence that is the beginning of a hiking
trail. I have heard of that trail called hidden valley, I personally don't know what
it's called. There is a lot of switch backs and is mainly a skinny single track on
the side of a hill. There are some point where there are roots sticking out, but
they are nothing big, and are easy to go over.

Getting there
Depending if you're coming from the boat launch, the south side swimming
area, the camping area, or the dam, there are lots of trails and fire roads to ride
here. There is a lot of simple, easy fire roads, covered in gravel, or there are
hiking/cow trails that can get pretty technical. I start at the top of the road
leading to the boat launch/camping/swimming area. Or from the south side at
the very end of the parking lots and going up the hill toward the water tower.

Rider questions

Q: All - I am a Bay Area rider and looking for some additional details on Lake Del Valle. Specifically, I've heard of four awesome singletrack trails (S Curves, Chutes and Splatters, Ravine, and Turantula). When I look at the park map, none of these are listed/shown. Can someone share some additional insights to where these are? Off of which fire road...? Near which turn-out...?

    This is a great place to ride if you know where to go. I park at the top cattle gate above the park entrance as the previous review mentioned. There are many single track options. Fast and tight at times make it fun. I always climb out on other available trails.
    I'd give it a five for what's available in the area but the cattle can be problematic. Been chased on climbs. Air horn does the trick...

    Pretty awesome place. There at least 8 different trails that I've ridden that are considered bootleg trails. The guys that ride out here usually are the ones that do the maintenance on those trails too. These are the ones that are single track and a ton of fun. Some areas difficult/technical. There are several jumps built by people we know. Super cool park rangers and awesome folks on these trails. Come early to beat the heat.

    I usually park at the top of Del Valle rd before the park entrance (not at the marina) and if you come with a group of 3 or 4, you can use one truck to shuttle from the marina back to the top of the hill instead of climbing.

    Overall an awesome place to try out your skills. Definitely has some tricky downhill runs. I did fracture my ankle this past ride so I'd say this place can throw curve balls.

    At the arroyo staging area it is a very steep long climb to the top, on the back side of the summit you can ride singletrack to the other side of the park, its full of ups and downs, ruts, and cattle.
