Nice Park and really cool that the Bison can roam freely in the park. They have multiple signs to make sure you are aware. And it does ask to keep your pets in certain areas I think only one trail is pet friendly.. so double check before you bring your friend. so not to disturb the natural wildlife and keep your distance for safety.. please follow their rules. They have a Guided Bison Saunter available on select dates but you have to call early to confirm. I wish I could have joined. Maybe next time. The restrooms are available in the prairie nature center when open.
