Birch Hill Recreation Area Singletrack
Fairbanks
Flowy summer singletrack on the same hillside as one of Fairbanks' premier Nordic ski trail systems. The two uses do not overlap in season: bikes are welcome once snow is gone, but the Nordic Ski Club's winter grooming means the trails are ski-only from mid-October to mid-April, unlike the fat-biking venues at Chena Lakes and Goldstream Valley.
