Once on morse loop, look for friends trail. Take a left on Northwest and then a right on French Trail. Take french and then right on west side trail and take this back to the parking lot. If you get a map at the beginning of the ride and follow the trails as above, you will be able to pick out my route. Its all well marked.
Granite hills upper loop, french, friends, and west side trail are the technical stuff.
If your a beginner, steer clear because it will be frustrating. I'm giving Borderland 5 stars because of its fun factor - I ride the same thing each week and always seem to find something new and fun along the way. I've been riding this park for a few years now, and the park has trails for all levels. The route which I mentioned above is great. Its quite technical and fun, however it is not very long at all.
