At 5,204 feet, Humboldt Mountain is just under a mile in the sky. The route to the top is a mostly paved (with some dirt and gravel sections) forest road that people drive, bike, run, and hike up. The road is mostly exposed to the sun and is a pretty steady grade the entire way. The views from the top are great, and you have the opportunity to check out some old ruins and tanks along the way.
