Cuyuna Country State Recreation Area

The Cuyuna Range was one of Minnesota's three great iron ranges, opened in the early twentieth century and named, the story goes, for a prospector and his dog. For decades miners pulled iron and manganese ore from open pits and underground works here, and the towns of Crosby and Ironton grew up around the industry, sharing in both its prosperity and its dangers.

Mining on the range wound down through the middle of the century as richer or cheaper ore was found elsewhere, and the last operations eventually closed. The pits, no longer pumped dry, slowly filled with clear groundwater, and nature reclaimed the tailings and waste ground, setting the stage for the area's later transformation into a place of recreation rather than extraction.

The best-known chapter in Cuyuna's revival is its mountain-bike trail network, built over the old mine ground with the steep ridges and deep pits shaping flowing, rolling routes for every level of rider. The trails have earned national attention and helped turn Crosby into a trail town, with shops, cafes, and rental outfits catering to the riders who arrive on summer weekends.

The water is just as much a draw. The flooded mine pits form deep, clear lakes stocked with fish and ringed by forest, ideal for kayaking, paddleboarding, and swimming, and their unusual clarity and depth make them a rare inland spot for scuba diving. The recreation area threads trails, campsites, and water accesses through the whole reclaimed range.

This region is Ojibwe homeland, part of the Anishinaabe country of central Minnesota, where lakes, rivers, and forests have supported the harvest of wild rice, fish, and game for many generations. The Mille Lacs, Leech Lake, and other Ojibwe communities carry a living presence across this part of the state, and their ties to the land and water here run far deeper than the century of mining.

The clear water that makes Cuyuna's pit lakes so striking is itself part of the region's character, a country of clean, cold lakes in a forest of pine, birch, and aspen. Loons call from the water, eagles fish the pits, and the woods hold deer and other north-woods wildlife, all thriving on ground that a lifetime ago was raw mine.

Summer is the peak, when the trails are dry and fast, the pit lakes warm enough for swimming and diving, and the trail town is at its liveliest. Early morning and evening bring the best light and the quietest trails on busy weekends.

Fall may be the finest season of all, when the birch and aspen over the old mine ridges blaze gold and the cool air makes for perfect riding. Spring greens up the forest and opens the water, and winter turns the area over to fat-tire biking, skiing, and snowshoeing across the snowy ridges and frozen pits.
