Backbone State Park
Iowa’s first state park protects a narrow dolomite backbone, spring-fed stream, forest trails, and CCC-era structures.
Artwork inspired by Grant Wood
The “Devil’s Backbone” is a resistant Silurian dolomite ridge above the Maquoketa River, giving the park more relief than many first-time visitors expect. Forest, trout water, caves, and Depression-era craftsmanship fit into a compact network.
Walk the ridge when dry, then contrast it with a river-level trail. Rock edges are unguarded, cave access is seasonal, and weekends crowd the central road; an offline map helps distinguish short loops from connecting trails.
Shape the visit around silurian dolomite ridge and ridge walk plus river-level contrast, which reveal different scales of the same landscape. Budget Half day–weekend for Backbone State Park: establish iowa’s first state park first, then reserve a final pass for silurian dolomite ridge.
