A spaciously wide layer of crushed limestone on the trail connecting the parking lot and the archaeological site has the feel and functionality of concrete, providing greater accessibility. Visitors will first encounter 12 feet of lawn and then reach the trail, which runs approximately 900 feet to the pavilion.
Service animals are always welcomed.
Thanks to a Thumb Area Boy Scout troop, two benches offer visitors a place to rest along the hiking trail.
Pets accompanied by and under the control of their human friends are welcome on the grounds of this site. Pets may not enter any building. For more information, see the Department of Natural Resources Pet-Friendly Rules.
