Iowa's Oldest State Park With Trails, Trout, and a Limestone Backbone
Iowa's Oldest State Park With Trails, Trout, and a Limestone Backbone
Iowa has a geographic secret in its northeastern corner, and Backbone State Park holds it. While most of the state lies flat under glacial till laid down during the last ice age, a region called the Driftless Area escaped glaciation entirely, leaving behind a landscape of dramatic hills, rocky bluffs, spring-fed trout streams, and limestone outcrops that feel borrowed from somewhere much farther north. Backbone State Park sits in the heart of this terrain, dedicated in 1920 as Iowa’s first state park, and still considered the most visually striking in the state.
The park takes its name from a narrow fin of limestone bedrock called the Devil’s Backbone, carved by a loop of the Maquoketa River over millions of years into a ridge that forms the highest point in northeast Iowa. A trail follows the spine of the ridge through twisted cedars and wind-sculpted rock formations, with views that drop sharply on both sides to the river valley below. It is genuinely surprising terrain for Iowa, and the Backbone Trail is one of the most distinctive hikes in any Midwestern state.
The park’s 2,001 acres include 21 miles of multi-use trails that accommodate hiking, mountain biking, horseback riding, cross-country skiing, and snowmobiling in winter. Backbone Lake, created by Civilian Conservation Corps dams built on the Maquoketa River in the 1930s, offers swimming, boating with electric motors only, fishing, and kayaking, with rentals available at a historic stone CCC boathouse. Backbone Creek and the adjacent river support naturally occurring rainbow and brown trout, and the park is considered one of the best trout fishing destinations in Iowa.
The park’s CCC heritage adds an architectural dimension that enriches every visit. Stone lodges, picnic shelters, trail steps, dams, and retaining walls built between 1933 and 1942 give Backbone a coherent rustic character that many more famous parks lack. The Iowa Civilian Conservation Corps Museum, open Friday through Sunday from late spring to mid-fall, provides context for this history near the park’s west gate.
Backbone is genuinely well equipped for families and groups. The park offers modern two-bedroom and renovated one-bedroom cabins available for year-round reservation through Iowa DNR, along with two campgrounds with more than 125 sites. For those wanting more space or privacy, vacation rentals in the surrounding Dubuque County and Delaware County area provide cozy country homes with fire pits, BBQ grills, and relaxing rural views. Dubuque, about 40 miles east, and Cedar Falls, roughly the same distance west, are the nearest larger cities with full rental inventory.

Top 3 Facts about Backbone State Park
Backbone State Park was dedicated on May 28, 1920, as Iowa’s first state park, making it one of the oldest state parks in the Midwest. The park’s defining feature, the Devil’s Backbone, is a narrow limestone ridge dating back approximately 430 million years, formed when Iowa was submerged under a warm shallow sea. It is the highest point in northeastern Iowa.
Backbone Lake was created in the 1930s by the Civilian Conservation Corps, which built two stone dams on the Maquoketa River, flooding a portion of the valley into a recreational lake. The CCC also built the park’s stone lodges, picnic shelters, bridges, and trail infrastructure between 1933 and 1942, much of which remains in use today as part of a historic district listed on the National Register of Historic Places.
Backbone State Park lies within Iowa’s Driftless Area, a region of northeastern Iowa that escaped glaciation during the last ice age. Unlike most of Iowa, which was smoothed flat by glacial deposits, the Driftless Area retains its ancient river-carved topography of deep valleys, bluffs, and spring-fed streams. This unusual geology supports native trout populations rare in the broader Midwest.
Travel Tips
Plan Ahead
Cabins and all campsites at Backbone are 100 percent reservable and require advance booking through Iowa DNR at reservenow.com, particularly for summer weekends. Kayak, canoe, and paddleboat rentals are available from the park concessionaire at the historic CCC boathouse during the summer season. Only electric motors are permitted on Backbone Lake. Contact the park directly at 563-924-2527 for current trail conditions.
Pack Appropriately
Wear sturdy footwear with good grip for the rocky and often steep Backbone Trail, which involves stone steps and narrow ridge sections. Pack insect repellent for summer trail use, particularly near the lake and stream corridors. Bring layers for variable northeastern Iowa weather. Anglers fishing Backbone Creek need a valid Iowa fishing license and must follow current trout season regulations.
Respect Wildlife
White-tailed deer, wild turkeys, foxes, and over 100 bird species including rare peregrine falcon sightings inhabit the park. Keep dogs on a leash at all times throughout the park. Stay on designated trails to protect the fragile limestone ridge and ravine ecosystems. Do not disturb or remove any wildlife, plants, rocks, or natural features from the park.
Stay Informed
Check the Iowa DNR website at iowadnr.gov for current trail conditions, seasonal closures, and water levels before visiting. The park office at 563-924-2527 provides current conditions including trout stream access and horse trail status, which can close in wet conditions. Flash flooding is possible in the Maquoketa River valley after heavy rains.
