Majestic Natural Beauty at Cold Water Spring State Preserve

Cold Water Spring State Preserve is a captivating natural area located just outside Decorah in northeastern Iowa. This preserve stands apart in the region for its striking geological features and pristine spring waters, offering visitors a quiet retreat into nature's purity. The preserve centers on a cold spring that emerges dramatically from the base of towering limestone cliffs, feeding into the clear, rushing waters of Coldwater Creek. These cool springs carve through unique rock formations dating back hundreds of millions of years, revealing the ancient limestone layers that define the landscape.

Visitors can see immense cream-colored limestone walls rising steeply along the creek, creating a natural fortress-like appearance. The serene creek meanders through farmland before reaching the rocky reserve, where the water cascades and bubbles over stones shaped by time. The preserve’s ecosystem supports native plants and wildlife unique to this limestone creek environment, adding to the sense of remote wilderness.

Cold Water Spring gained protection as part of Iowa’s state preserves program, aiming to conserve areas with notable scientific and ecological significance. With no developed amenities and limited parking, it appeals to those seeking a purely natural experience. Hikers often stop at a former bridge site to cross the creek and follow rugged trails that wind alongside the spring. It’s a peaceful spot to rest, surrounded by the sounds of water and wildlife, and many describe it as a perfect picnic location free from crowds or distractions.

This preserve invites visitors to witness one of Iowa’s best examples of untouched cold water springs and limestone landscapes, offering refreshingly cool waters and dramatic scenery in a quiet, natural setting.
