Backbone State Park sits along the Maquoketa River near Dundee in Delaware County, offering 2,000 acres of some of Iowa’s most dramatic scenery. The park takes its name from a narrow, steep-sided ridge of bedrock — the “Devil’s Backbone” — that rises sharply above the river valley, creating rugged terrain unlike anything else in the state.

This is Iowa’s oldest state park, and it shows in the best way. The Civilian Conservation Corps built much of the park’s infrastructure during the 1930s, and those stone shelters, bridges, and towers remain beautifully intact, giving Backbone a character that newer parks simply can’t match. The CCC lodge and cabins are worth seeing even if you’re just passing through.

Hikers will find over 20 miles of trails ranging from easy riverside walks to challenging scrambles along the backbone ridge itself. The park draws rock climbers to its dolomite bluffs, anglers to the stocked trout streams, and mountain bikers to dedicated singletrack. Backbone Lake offers swimming, kayaking, and fishing during warmer months.

Camping options include both modern and rustic sites scattered through wooded areas, plus seasonal cabins for those who prefer a roof overhead. Sites fill quickly on summer weekends, so book early.

Visit in fall for peak color along the ridge — the contrast of red and gold foliage against pale limestone is stunning. Spring brings trout season and wildflower displays along the river bottoms. With a 4.7-star rating across nearly 2,000 reviews, Backbone consistently ranks among Iowa’s best outdoor destinations.
