Mountain bike - huzzah!
Great trail right within the town of Jackson. Not too difficult (gain about 1000 ft), and going down game creek is quite fun. Maintained well, but it's usually a little wet up until July. Be careful if you're hiking, it's being used more and more for mountain biking...good idea to keep on your toes throughout.
