6. Arroyo Burro Hike
Hard, steep, best to test stamina (11.2 miles out and back 3000 ft elevation) and best of the list. Start early (7am) to avoid trekking in dark on the way back. At times one may feel lost after about 300 feet downhill, but the fun begins from there with the forest cover. Sudden cooling at some spots makes one realize the importance of trees and streams. Recent rains have activated the streams.
