The National Forest Hiking Trail that is attached to our park leads it’s way to the Grindstone Reservoir. The hike is about 45 minutes and goes through the National Forest. By car, Grindstone Lake is 1.8 miles away and will take you 5 minutes to drive to. Grindstone Lake is one of two lakes in the area that allow non-motorized boats for fishing. Fishing includes rainbow trout and occasionally catfish and smallmouth bass.
