Guardian Trail is definitively the best all trail in Bidwell Park. It is for intermediate to advanced technical and downhill riders, but really does contain a little bit for everyone. There are great views, smooth singletrack, rocky technical and downright dangerous sections. A must ride! Whether you're doing a downhill shuttle run or an out and back loop, this trail does not disappoint. This trail hugs the southern ridge in the Chico Creek canyon. There are numerous technical sections throughout the ride, some of which have dangerous cliffs and drops if you don't stay on the trail. So don't plan to ride the entire trail unless you have some experience riding, and come prepared to walk many sections. The climb uphill is moderate to strenuous, but none of the steep sections last for longer than 100 yards. The climb up can be completed in less than one hour if you're in decent shape, and the downhill in 30-60 minutes. For reference, Mark Weir made it down in just under 19 minutes. There are lots of rocks, some small jumps and drops, so a full suspension bike is recommended. From the bottom there is an initial technical rocky section of about 1.5 miles. You will come to a post above the golf course where the trail forks. The left/downhill side goes to the Annie Bidwell trail. The right/uphill side goes to Guardian Trail. After this point, the climb becomes much smoother and less technical for the next 2 miles. When you notice large cliffs looming over the trail to your right, the trail becomes quite a bit more technical. As you move past the cliffs the trail will smooth out for the remainder of the climb. The trail ends when you hit the doubletrack fire road (Ten Mile House Road).
It's a great long ride with amazing views . Can be narrow and technical requires low speed stability skills.
This ride is for the expert. The trail starts out fairly easy but quickly becomes expert. It's single track with rocky terrain and cliffs. It was more of a trail than I bargained for with my level of riding.
