Mesa Falls is just north of Rexburg idaho up in the Targee national Forest. It's an easy walk to the falls for any family activity. There is also a gift shop there with many things to buy and photos. I believe it closes at 5 on the weekdays. Bring lots of bug spray if going in the month of May and June. There is also really good camping near by that my wife and I want try out come 4th of July weekend. In the river near the falls the fish are everywhere!! So many of them they also have food that you can buy for a quarter to feed them.
