The trails here are an absolute gem of Organ Pipe National Monument and take you away from the potentially more crowded areas of the park. There is something for everyone regardless of whether you want flat running, vert, technical trails, or flowy singletrack. The trail around Estes Canyon and up to Bull Pasture is well maintained and not very technical. You can make a longer run up to the summit from Bull Pasture if you want an extra challenge.
