The Jones Park Trail, while mostly downhill, still has a good amount of climbing--not what you want to see after slogging up 16 miles of Gold Camp Road. Also probably not what you want to see if you're shuttling. What the Pipeline trail gives you is a much straighter, and almost all downhill path to the same outlet. Remember to veer left on trail 622 A rather than right down 622 (aka Seven Bridges Trail). Then hook right on 667 (this is where you meet back up with the Jones Park downhill route. About a mile later, trail 667 bears right. For the longest downhill, bear left onto trail 666 aka Bear Creek Trail. This is a very fun downhill extension with some technical spots, some spooky exposure, and fantastic views of a very rugged canyon. You will merge onto High Drive, where you could leave a shuttle vehicle (beware, however, High Drive is one way and only open in the summer months). Between the Falcon Guide "Mountain Biking Colorado Springs" and Trails Illustrated 137 "Pikes Peak, Canon City," this one's pretty easy to piece together.
Look up the directions to the Jones Park trail. They share the same trailhead. From where you park your shuttle vehicle (if you shuttled--highly recommended), instead of taking trail 701 to the left, go straight down trail 668--this is the pipeline trail.
