Backbone State Park Beach, located within Iowa's first state park, offers a serene retreat along the Maquoketa River in Dundee. Known for its striking geology, including the iconic Devil's Backbone ridge, this beach area combines natural beauty with recreational opportunities. Visitors enjoy swimming in Backbone Lake, surrounded by dense oak and maple forests, while the park's CCC-era structures add historical charm[1][4]. The vibe is family-friendly, with a mix of tranquil nature escapes and active adventures, making it a year-round destination for hiking, fishing, and seasonal water activities[2][5].
