Sutro Tower Trail

Sutro Tower Trail is a short mountain biking route in San Francisco, about 0.3 miles from the community of Forest Knolls. The trail is an out-and-back, roughly 0.4 miles long, with a low point of 781 feet and a high of 820 feet. The climb is rated moderate, and the one-way elevation gain is 13 feet. Late summer and early fall are the most comfortable times to ride. Typical averages from a nearby weather station in downtown San Francisco show September highs around 70°F with lows near 56°F and only about one wet day in the month. That station sits about 670 feet lower than the trail, so temperatures on the route run cooler. Several other routes start close by. North Ridge Trail and Historic Trail are each about 0.3 miles away, and Steep Ravine Trail is about 0.4 miles off. Climbers can find Main Cliff Band about 1.1 miles away.
