      Fairly good size area that includes mostly beginner to intermediate trails. Lots of dog walkers and a few horses so pay attention. The North Side of Callahan is a little more challenging and also includes Gibbs Mountain which can be a tough climb up but is a pretty fun going down. On the other side of the large meadow there are a few single track trails but mainly its just double track. Callahan has great potential for some purpose built trails, but they just need to be built.
