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!

This was an amazing hike on a hot summer day.

1) take Hamms Gulch all the way up to Spring Ridge trail. Make sure you go left from the bridge, and go next to the stream. This way you will do the climb in shady redwoods. Otherwise you will end up climbing on the sunny side.

2) once you get to skyline blvd, stay right and the path goes along skyline for a few yards

3) stay left to follow Spring Ridge trail. This is the no-shade part

4) take Hamms Gulch to the right and follow signs to Alpine road.

If in doubt, see my saved trail/map. Good luck and carry water and snacks.

This is superbly beautiful. The loop I did took the Spring Ridge trail instead of the Lost and Razorback Ridge trails. Spring Ridge trail has lovely open meadows and wonderful views, and Hamms Gulch trail takes you down through the forested area around the gulch. It was a perfect afternoon hike/walk.
