Rocky Arbor is a state park in south-central Wisconsin. The park was formed from late Cambrian Limestone from shallow seas at the time. Much later, the Wisconsin River washed over and carved channels into the limestone. The river has since diverted its course but the carvings and limestone remain intact. The park has an abundant number of campsites, a picnic area, and a playground as well as a hiking trail. The gate is closed during off-months but visitors can park at the gate and walk in.
