The Mines of Spain State Rec Area is an amazing outdoor space that the entire family is sure to enjoy. In its 1,380 acres, you’ll find archaeological sites found by French explorer Julien Dubuque as well as Dubuque’s final resting place. Other aspects include the E. B. Lyons Nature Center, the Betty Haputli Bird and Butterfly Garden, 15 miles of hiking trails, four miles of ski trails, and several picnic areas. One of the most unique natural features you’ll come across in the recreation area is Horseshoe Bluff, a horseshoe-shaped area where you’ll see Ordovician dolomite and stunning rock features.
