This trail system is fun and flowy for most of the year. But, when snow sets in, it changes the difficulty quite a bit and some of the trails have small margins for error. This is why I ride this trail system in the winter; it is great for training with the steep climbs and with snow partially dangerous downs. This is a route I use to practice and train for climbing on my fat bike.
Start out by heading up the main dirt road into Blodgett Open Space on St. Francis Road then hang a right on what is supposedly called Hummingbird Trail. From there, we finish our first climb and turn right on to Ponderosa Trail and go all the way back down.
