Around Bethel College campus in North Newton. Exit number 34 off of Interstate 135. Bethel College is just south of exit. Many places to park - see map.
Trailhead is east central part of campus.
There certainly has been, and perhaps still is, a good attempt at maintaining main portion of trail with wood chips and signage. Easy to get to location on Bethel College campus just off I-135. The portion of the trail on the west side of K-15 is generally concrete and can be avoided if you wish. K-15 and Sand Creek is generally excellent even if short and can be run in most any weather. Lots of shade trees on this portion as well.
