The 546 acres which comprise the total park area were first developed in 1930 to function as an honor farm for 30 to 40 state prison inmates. Various crops and livestock produced on the farm were used for the prison operation. Many of the original farm structures remain, including the dairy barns, slaughterhouse and dormitory building. The farm property was turned over to the Idaho Department of Lands in 1977, and in 1978 the property was transferred to the Idaho Department of Parks and Recreation for a state park. While unable to explore inside the farm structures, you are able to come and walk around the original farm structures and see what they look like!

We also offer Gootium backpacks that contain all that you need for a self-guided trek through the park.
