There is this awesome place in Raft River Idaho called Stedman Ranch. It is a family named the Stedmans home, and they let people/groups come play on their toys. They have two HUGE water slides, one is 700 feet long, and the other is 500 feet long. They have all the tubes and boards to go down the slide with. There is a fire pit, restrooms, a beautiful water fall, grass to set tents up on, underground trampoline, Frisbees, balls, and a candy cannon. They fill it with candy and shoot it way up in the air, then the kids get to run around and pick it all up. The kids loved it. There is also a 500 foot zip line...such a rush. The only thing is that you have to reserve your time like a year in advance, but it is so worth the wait. I highly recommend going.
