Historic Island in Thousand Springs State Park — Snake River Canyon Setting With Massive Natural Springs, Historic Minnie Miller Dairy Farm Buildings, Day-Use Hiking and Photography, Kayaking and Paddleboarding on the Snake River, Dramatic Canyon Scenery With Springs Cascading From Basalt Cliffs, Site of the Annual Thousand Springs Festival of the Arts, Near Hagerman Gooding County South-Central Idaho
Ritter Island (a unit of Thousand Springs State Park) is a historic island and day-use area on the Snake River in the Hagerman Valley, Gooding County, south-central Idaho, managed by Idaho Department of Parks and Recreation. The island features the preserved historic Minnie Miller dairy farm buildings from the early 20th century including the farmhouse and barn, day-use hiking trails and photography viewpoints, kayaking and paddleboarding access on the Snake River, dramatic Snake River Canyon scenery with massive natural springs cascading from basalt cliffs — part of the legendary Thousand Springs formation, the annual Thousand Springs Festival of the Arts, access via the steep Thousand Springs Grade road down into the canyon, a pedestrian bridge connecting the mainland to the island, picnic areas with canyon views, and one of Idaho’s most unique and photogenic state park settings.
The Thousand Springs are one of Idaho’s most spectacular natural wonders — water from the Lost River Range aquifer emerges from basalt canyon walls in massive cascading springs that have been flowing for thousands of years. Ritter Island sits in the heart of this geological phenomenon.
The Minnie Miller story adds historic depth — in the early 1900s, she built a state-of-the-art dairy operation on this remote canyon island, using spring water to cool milk in an era before refrigeration. Her preserved buildings remain as a testament to pioneer ingenuity.
