South Ridge trail/road is the primary means of climbing to the top of Horsetooth Mountain park from the upper trailhead, as a part of a larger loop ride. The road climbs about 1000 ft in 2.6 miles. This trail parallels the hiking trail to Horsetooth Rock. MTB access ends below the last section of hiking trail to the top of the Rock. The surface is dirt, on the loose side, with lots of small rocks. The climbing is steady, but punctuated by a number of water bars. The climbing gets steeper towards the top, but the lack of technical obstacles minimizes the number of high effort pedal strokes needed to reach the top. There is very little shade on this route, which means it can get hot. This service road is not as steep as the Towers trail/road, which is another popular route to climb.
