There are several places you can go tubing when camping at Cook Forest State Park. We didn’t really plan ahead, and ended up checking out three places before we actually hit the river.
Take our word for it, make yourself a reservation if you’re skeptical. Or, figure out a way to take your own tubes and get dropped off and picked up. Our first choice would probably be the best place, but we opted out due to long lines and our own impatience. 😉
