So the first place I rode was Curt Gowdy state park. Fun trails about 25 miles west of Cheyenne. The only thing I couldn't get over was how limited traction was in the loose granite that the trails were made of. A way fun system of trails though, especially if you are into slow technical riding.
I put in tons of laps at the Cheyenne North Park Bike park. It is a fun little course with a flowy little drop line that lasts all of 15 seconds.
Then I was told to ride the "Happy Jack Trails" I will say they were by far the most fun system of trails I got to ride.
Smooth flowing Wyoming single track.
With some fun rough sections too.
And some great vistas.
