Trail Description
About this trail
The route Varies. There is sigletrack, fire roads Bmx jumps and sweet Downhill sections. I would not suggest riding alone!! I know lots of people who have sighted Mountain Lions!! Bring lots of water and know where you're going!

Update: These trails are on private property (Pacific Union College) and as such they are not officially sanctioned for riding outside 2 official races each year (Howell Mountain Challenge and Napa Valley Dirt Classic). Also, please avoid this trail on Saturdays out of respect to the landowners. No trail signs in this remote area, ride with extreme caution at your own risk.

Review: I was not able to ride all today due to equipment failure, but what I did ride was pretty sweet. There is a variety of trails/ roads. There is also a lot of Poison Oak. There is some mild inclines/ declines, as well as some painful incline/ decline, 8 degree! Some roots, rocks, loose soil, solid rock, it has all of it. Leaf covered areas are extremely slick. There are many more trails than any maps I've found. Very little to no trial markers.

Review: Lots of variation on this network of trails. We picked up a map at the airport (they were nice enough to photocopy the last one), but I can't say the map helped that much. Nothing is marked. We got lost, but it wasn't a bad experience as the trails are beautiful and offer different options for different levels of experience.

Review: Super good place for mountain biking. My favorite loop is serpent - heartbreak hill - ridge road - Angwish - then back home. Go to the Angwin Airport for parking and if you go inside the little terminal they have trail maps.

Review: VERY, very fun trail to ride. TRAIL IS NOT CLOSED, was just there 1/9/11. Be courtious and ALWAYS stay on legal trails, and ALWAYS bring some type of trash the idiots leave.

Review: I have to say that these trails are NOT in Las Posadas forest, so the name of these rides are incorrect. BUT, these are some of the best rides that you will find in the Bay Area. Amazing single tracks cover the entire property

Review: Lots of winding singletrack if one knows where to look including a 3 mile basically nonstop stretch. Also people have been building stunts in various areas including 8' jumps and ramps, etc. Trails maintain really well even in the winter, hardly any mud on most of them except Lower Loop. Two races held yearly. Lots of poison oak in the area so beware. About mountain lions, they are around, but I've never seen one and been riding the trails for 15+ years.

Review: Great variety. Short linking trails between fire roads. Minimal user conflict with horses and hikers. Map shows college property. Go south into 4H camp for trail descents and fire road return.

Review: Lots of new single track, Wish there was a parallel along ridge above over look not just straight downhill. One long single track miles long would be nice

Review: Fun ride. There is some free ride stuff at one point off the main trail (burms, doubles, tree rides, etc.). There is some awesome switch back single track that goes on forever through manzanita groves. All of the above is not on any map.
