Wish I had had more time to explore this system as there are lots of options here. Not a huge area but loops around and through the middle with plenty of steep hills make this a nice challenge, or easier rolling terrain. Stay left on a counterclockwise loop for the stream trail which is flat and fun!
A nice loop trail in Windsor, CA with great views of the vineyards and beautiful trees. We did this on a Friday morning and barely encountered anyone on the trail. The elevation gain was not insignificant (1000 feet), and on a hotter day it could have been a better workout, but pretty decent overall.
