Dark Side

Dark Side is a short, hard mountain biking route in Trione-Annadel State Park in California, managed by State Park and Recreation. It sits about 0.17 miles from the park's center, and the whole trip is an out-and-back of about 0.34 miles with a total climb of 133 feet. The route is short but steep. The steepest part comes at about 0.11 miles, with a grade of 6 percent, and the climb is roughly 58 feet one way. That makes it a quick but challenging ride for mountain bikers. Late spring and early fall are the most comfortable times to go. Typical averages from a nearby weather station in Santa Rosa show May highs around 74°F and October highs near 79°F, while winter brings the most wet days, about 13 to 14 a month from December through February. Several trails start close by. The North Burma Trail is about 0.2 miles away, the Warren Richardson Trail about 0.4 miles, and the Two Quarry Trail about 0.5 miles. Paddlers can find Santa Rosa Creek about 2.4 miles off.
