As you head down Highway 191 from I70 towards Moab, the first set of trails you hit are in the Klondike Bluffs area. There are several fun rides here. Because they are short, you can stitch them together in a variety of ways.
At the north end of the park are Alaska, Homer and Nome. I rode up Mega Steps to Alaska. At the top of the trail the views of the Salt Valley below are stunning. And you have great views to the south and west too.
