My kids like to take inner tubes and tube the river, there is a tube service just south of the park that rents tubes and also provides a shuttle. We also like the Kolob Terrace and the west side of the park of interstate 15. Write if you want more specific info. My family and I are planning on taking a trip soon to Zion's, but don't know what places would be nice to visit. Also, we're wondering what kind of clothes and equipment we should plan on taking if we are leaving at the end of May and staying for about three days.
Creek is good too.
