Welcome to Milton KOA, where we've been making memories in Southern Wisconsin for over 25 years.
Nestled in the rolling hills of the Southern Wisconsin countryside, Milton KOA is a family escape to fun, excitement, and relaxation that feels worlds away from the frantic pace of everyday life, yet is close to countless great attractions near the Wisconsin/Illinois border. After 23 years as Hidden Valley RV Resort, we adopted the KOA Yellow into our family-owned and operated tradition of being a destination for our guests to make incredible memories year after year!
