Like lots of kids, my daughter read the Harry Potter books when she was in grade and middle school. Later she talked me into watching the movies, which we still enjoy watching very much.
The cache is located along a very scenic crushed limestone and gravel trail that encircles McKnight Lake.
The hike around the entire lake is about 1.6 miles from the suggested parking coordinates. The trail is bikeable on any kind of mountain or road bike with reasonably wide tires. Enjoy!
