Krug.... This is a tough course by all standards. It can be confusing with multiple trail crossings, and the 5.5 miles in the loop can seem like 10 or more. Hills are long and steep, and left over from a time when trails were built straight up and down the contour of the slope. Washed out and rooty climbs/decents are the rule. Even still, once the subtle charm of the trails are realized, a love affair with this trail system quickly blooms.
Summer is a tough time in Krug park though. Idiot teenager vandalism, and massive spider-webs every 5-10 feet at face level can ruin the experience of this trail pretty quickly. However, between the months of November and May, Krug park is some of the toughest, best mountain biking you will find in Saint Joseph, or anywhere.
