Bill Spring is a moderate level difficulty trail connecting the Sulpher Canyon and Doc Long Picnic areas up to the intersection with the Faulty and Oso Corredor Trails. The lower section is characterized by fast, straight sections with abrupt trail blockages intended to slow downhill traffic. Be mindful of these and hikers (which tend to be plentiful) on the way down. The upper section has some slightly more technical moments, but nothing above an intermediate level. Bill Spring ends at the junctions of Faulty and Challenge trails.

Access Info

Park at the pull-off below Sulphur Canyon or park at the picnic areas ($3 day use fee)

      Looks like a dry stream bed with all the loose rocks, but oddly is right next to a dry stream bed. Kinda blown out by hikers being so close to the paved parking, but this is how you get to the better trails. Eventually hikers turn around and it turns into a good singletrack.

      I use Bill Spring to start and finish my ride when I do a big climb+descent up to Sandia crest/ski area. Its also a good ending to park your vehicle for the end of a shuttle ride from the Sandia peak. The lower portion is a nice mellow climb, but you'll have to cross the stream a few times IF it's running and not dried up. The upper portion of this climb is not easy however and this is coming from someone who loved a challenging and technical climb. It's VERY steep on some parts with technical moves during those steep sections. I end up having to walk some short sections after a try or two usually. It'd fun coming down though!! Watch your speed as there is a lot of hikers in this area, especially on weekends during the warm months.

      We hope you've been enjoying Trailforks!
