Lily Lake Trail is a wide, easy graveled trail that circles Lily Lake. It is only 1 mile long and is perfect for strollers, wheelchairs, and people who aren't in the mood for a strenuous hike. If you want something a little more adventurous, add the Lily Ridge trail in, which branches off of the Lily Lake trail, climbs up along the ridge, and then drops back down to the lake. The Lily Mountain trail also starts nearby, for a true mountain hike.
