Big Bull Creek Park celebrated its grand opening in September 2018. It is the largest park in the JCPRD system totaling 2,060 acres and is located between Edgerton and Gardner in southwest Johnson County.

The Grizzly route traverses Glacier National Park on some of its northern most trails.  The route was named after one the trails most common travelers, the mighty grizzly bear.  Keep your eyes up if you want to catch a glimpse of this mighty beast, but don't forget to look down if you want to avoid stepping in the very plentiful grizzly droppings. The trail traverses some of the most beautiful, wild, and difficult to reach trails in all of Glacier National Park. Expect the unexpected!

This route can be run in either direction.  Described below is the east to west route.
