Starting from the Bumblebee Trailhead go north onto the BCT. The first 4 miles are a little technical with rock sections, tight turns and good sized drop offs. After the fast doubletrack downhill you cross the run and the fun starts.
The next couple miles are a gentle climb with some fun cross country riding. Once this section ends at the next road there is a gentle p then down to Treasure Mine Rd. This section has a few tight turns, a little cat claw and some great views of the area.
