Nestled along the Des Moines River near Lehigh in Webster County, Dolliver Memorial State Park is one of Iowa’s most geologically striking destinations. Spanning 600 acres, the park is defined by its dramatic sandstone bluffs, deep ravines, and ancient copperas beds — mineral formations dating back millions of years that stain the creek beds in vivid oranges and yellows. It’s a landscape that feels more like the Ozarks than the Iowa prairie.

The park’s trail system winds through towering bluffs and along Prairie Creek, where hikers pass Boneyard Hollow — a narrow canyon littered with weathered animal bones deposited over centuries. The sandstone formations and exposed bedrock make this a favorite for geology enthusiasts and photographers alike. Beyond hiking, visitors enjoy fishing along the Des Moines River, picnicking on the bluffs, and wildlife watching in the heavily wooded ravines.

Camping is available with both electric and non-electric sites tucked among mature hardwoods, offering a shaded, riverside setting that fills up on summer weekends. Reservations are recommended from June through August.

The best time to visit is late spring through early fall. Spring brings wildflower displays along the canyon floors, while autumn transforms the hardwood canopy into some of the best fall color in north-central Iowa. Winter visits reward the adventurous with frozen creek beds and quiet solitude.

With a 4.7-star rating across 551 reviews, Dolliver consistently ranks among Iowa’s most beloved state parks — a hidden gem that rewards those who make the trip.
