This beautiful park is located where the Wisconsin and Mississippi Rivers meet and where in 1673 the first white men crossed the Upper Mississippi and stepped foot on what would become Iowa. There is access to the river near the park; and hiking trails beautiful views, picnic areas, volleyball nets and other activities inside the park. Mountain bikes are allowed on some trails and 77 camp sites are available. I believe the park is open year round but many facilities close for the winter. Start your visit at the Visitors Center. There is a park store that is open everyday from 10 AM to 4:30 PM, May through October.
