    Tips

    March 7, 2019

    Well paved road reopened in 2017, climbing sometimes steeply in switchbacks into the Sierra Azul preserve from Hicks Road to the former radar tower on the summit of Mt Umunhum. It's a great workout, but don't be discouraged by the exaggerated 2950 feet elevation change estimate here by Komoot (in biking mode it even calculates 9750 feet): in reality it's closer to 1600 feet of climbing.

      Climbing Mount Umunhum is a tough but rewarding challenge. The road is steep, with sections reaching up to 18% grades, so pace yourself. The views from the top are spectacular, making the hard work worth it. Start early to avoid traffic and the heat, and be prepared for a long, demanding ascent.
