Awesome. I took Hamm Gulch to Lost Trail, then connected to Spring Ridge. This route is dog friendly. Hamm Gulch is mostly shaded, and the incline isn't so bad with the switch backs. Spring Ridge is completely open with little shade, and a steep grade down. Spring Ridge is bike friendly, but not horse. I imagine if you took this route the opposite way it would be challenging, starting with the hill and sun. I logged 7.6 miles with 1475 ft incline. There is also a creek to cross when on Gulch, which is nice for dogs and horses to drink out of. There are some benches along the way as well. Would definitely recommend!
