For most travelers, the state of Iowa might not be a destination on the radar at all — but it certainly should be. Clinging to the banks of the Big Sioux River right along the border with South Dakota, this rural hamlet is full of surprises. Take a drive across the Big Sioux River for a glimpse of the rusty old railway truss spanning the calm waters against a backdrop of leafy trees. Bask in more riverfront views at Oak Grove Park, where fishing and woodland hikes await, or paddle around a tranquil lake and spend the night camping at Big Sioux Recreation Area. Travelers in Sioux Falls, South Dakota, can drive to Hawarden in about an hour, while Nebraska locals in Omaha are roughly two hours away.
