Backbone State Park Hiking Guide
Backbone State Park sits in northeast Iowa's Driftless Area, where a long loop of the Maquoketa River has carved a gorge through the landscape and left a narrow quartzite ridge standing alone above the water. That ridge, the Devil's Backbone, gives the park its name and its character. At roughly 100 feet above the river with near-vertical sides, it is modest compared to any western ridge, but it is genuinely striking in a state where the default terrain is row-crop flat. Iowa's oldest state park (established 1919) has been drawing visitors for over a century.
The park is not a single-draw destination. The Devil's Backbone and its trails are the main attraction, but the Civilian Conservation Corps stone architecture built here between 1933 and 1942 is among the finest surviving CCC work in the Midwest. The trout fishery in the Maquoketa River adds another reason to visit in spring. And the combination of multiple lakes, forest cover, and a campground gives the park a range of uses that most Iowa state parks cannot match.
What to Expect
The park's 2,001 acres cover a loop of the Maquoketa River and the upland forest on either side. The river here cuts through bedrock in a series of small gorges and pools, and the quartzite ridge that forms the backbone is the most dramatic section: a narrow spine with the river on three sides, accessible by a trail along the ridge top. Below the backbone, the gorge walls drop quickly to the river, and the views from the trail give a real sense of the erosional history that created the feature.
The CCC presence is visible throughout the park. The stone structures built by young men during the Depression years include a substantial concession building near the beach, multiple stone bridges crossing the river and its tributaries, rental cabins used for overnight stays, and a large stone beach shelter at the swim area. The construction quality is high, and the stone work blends into the landscape in a way that modern park infrastructure rarely manages. Walking the CCC Tour loop puts you in contact with most of the major structures.
The Maquoketa River through the park supports a trout fishery maintained by seasonal Iowa DNR stocking. The river pools below the backbone ridge are popular with anglers in May and June after stocking. Above the park, the river runs through more open terrain. Canoes and kayaks can be put in at access points within the park; the river is generally appropriate for paddlers comfortable with moving water and some minor obstacles, though conditions vary with water level.
Wildlife is typical of Iowa's forested Driftless valleys: white-tailed deer, wild turkey, great horned owl, pileated woodpecker, and a good variety of warblers and other songbirds during spring migration. The river supports wood ducks and great blue herons through the warmer months. The park's combination of forest, open water, and riparian corridor supports more species than the acreage might suggest.
Best Trails
Backbone Trail
5.5 mi, Loop, Strenuous
The main loop is the most serious hike in the park and the route most visitors come specifically to walk. From the trailhead, the route climbs to the top of the quartzite ridge and follows the narrow spine above the Maquoketa River gorge. Some sections require using hands for balance on the rough quartzite, and the drop below is real enough to demand attention. The views down into the gorge and across the forested valley are the best in the park. The full loop returns through lower forest, crossing several of the CCC-built stone bridges. October is the best month for this trail; the hardwood color peaks and the leaf drop improves views through the river corridor.
East Lake Trail
4.0 mi, Loop, Easy
The East Lake loop circles one of the park's smaller lakes through the mature hardwood forest of the CCC-era grounds. The terrain is gentle, the shade is consistent, and the trail passes near several of the historic stone structures. Good for birding in the wooded sections near the lake margins in spring and early summer. This is the most accessible trail in the park for visitors who want a substantial walk without the uneven footing of the backbone ridge.
CCC Tour / Auditorium Loop
2.5 mi, Loop, Easy
The interpretive tour of the Civilian Conservation Corps architecture makes a complete circuit of the main developed area of the park, passing the stone concession building, the stone bridge at the swim beach, several rental cabins, and the stone auditorium shelter. Brief interpretive signs at each structure explain the construction and the CCC program. For anyone interested in New Deal-era public works, Backbone's collection is worth a specific visit. The structures were built with a scale and craft quality that reflects how seriously the CCC took its construction mandate.
Richmond Springs Trail
3.0 mi, Out-and-Back, Easy-Moderate
The trail follows the Maquoketa River upstream from the main park area to the mineral springs that give it its name. The riparian corridor here is excellent for May wildflowers: wild geranium, bloodroot, trout lily, and hepatica appear in sequence through the month. Birding along the river is good from spring through late summer. The terrain is mostly flat with a few short climbs away from the river. The springs themselves are modest but make a logical turnaround point.
When to Visit
May and June are strong months. The trout fishing is at its peak after spring stocking, the wildflowers are active on the Richmond Springs trail, and warbler migration brings songbird diversity to the forests. Crowds are manageable in May but pick up on summer weekends.
July and August are the busiest months. The swim beach and campground are popular with families from Dubuque, Cedar Rapids, and the Twin Cities. Weekends fill the campground; reservations through the Iowa DNR system are necessary if you plan to camp from late June through Labor Day.
September and October are the quietest and most scenic months for hikers. Crowds drop after Labor Day, and October brings the fall color that makes the Backbone Trail worthwhile at any distance. The quartzite ridge shows warm orange and red in the oaks and maples from mid to late October. Temperatures are cooler and more comfortable for the ridge sections.
Winter access is informal. The park campground closes for the season, but the trails remain open for snowshoeing and walking when conditions allow. The stone structures look particularly good in snow, and the backbone ridge is striking without leaf cover.
Getting There and Logistics
The park is located on Iowa Highway 410, eight miles east of Strawberry Point. From Dubuque, take US 20 west to Iowa 13 north, then west on 410. From Cedar Rapids, take US 30 east to Iowa 13 north, then connect east to the park. The nearest airports are Dubuque Regional (DBQ), about an hour east, and the Eastern Iowa Airport (CID) in Cedar Rapids, about 90 minutes southwest.
Park fees: Iowa state parks require a daily or annual vehicle permit as of 2026. Verify current amounts at the Iowa DNR website. Camping at Backbone requires a reservation through the Iowa DNR reservation system and is a separate fee from the vehicle permit. The park has developed campsites, rental cabins, and a group shelter.
The park has no food services beyond basic vending. Strawberry Point, eight miles west, has restaurants and a grocery store. Dubuque, an hour east, is the nearest city with full services.
If you are building a northeast Iowa trip, Effigy Mounds National Monument is about 60 miles north and pairs well with a Backbone visit. Yellow River State Forest is another hour north of Effigy Mounds and adds a backpacking option. The three sites together make a logical multi-day loop through the Driftless Area.
Planning Tips
- The Backbone Trail involves real scrambling on rough quartzite. Wear hiking boots or trail shoes with firm soles. Sandals and casual footwear are not appropriate for the ridge section.
- Rock climbing on the backbone formation is permitted as of 2026, but the route selection is limited and the rock can be slick when wet. If you plan to climb, contact the park office for any current restrictions.
- For fall color, the peak on the Backbone Trail is typically the second and third week of October in northeast Iowa. The oaks hold color later than the maples; the full display usually runs from early October through the first week of November.
- Campground reservations fill quickly for summer weekends. Book through the Iowa DNR reservation system as early as reservations open if you plan a Saturday night stay from Memorial Day through Labor Day.
- Check the Iowa DNR website for current trout stocking dates before planning a fishing trip. The stocking schedule varies by year; showing up the week after stocking gives much better fishing than arriving at random. A current Iowa fishing license is required as of 2026.
Backbone is the most geologically interesting state park in eastern Iowa, and the combination of the ridge trail, the CCC architecture, and the river fishery gives it more depth than a single afternoon can cover. Treat the quartzite and the historic structures with care. Stay on designated trails on the ridge, do not climb the stone CCC structures, and follow Leave No Trace principles throughout.
