Clean and easy loop trail with no obstacles. The loop is a big square. The northern edge is in prairie. The main attractions are a cold bubbling spring with nice Boardwalk where one can touch the water, and a minor hill with 150ft vertical gain. Locally known as the picnic hill, the top offers panoramic views of Madison state Capitol and surrounding glaciated areas. The hill top also features five Native American effigy mounds. The western edge goes into the woods and crosses a couple bridges. The southern edge is on a loooong Boardwalk. After crossing one more bridge the eastern edge emerges onto prairie again, passing through a water tower, and enters Orchid Heights park with facilities. Sandhill cranes are occasionally sighted.
