UW Arboretum Big Spring Hike is a 2.5 mile loop trail located near Madison, WI that features a lake and is good for all skill levels. The trail is primarily used for hiking, walking, and nature trips and is accessible year-round.
Beautiful hike in the woods with well marked, but complex, trails. Can see some Indian earth mounds. Passes a spring that flows to lake Wingra. Minor elevation gain, easy for kids. Saw some puffball mushrooms on trees, lightly poking them gives out green cloud of spores.
