Shuttle bus!!!! Not sure why I didn’t see the bus mentioned in any of the other reviews. Most might ‘ass’ume it’s a known fact, for me it was a huge surprise. For any, I say again ANY of the trails in Zion you must take the free shuttle bus. You can either park in Springdale or if lucky inside the park but you still must take the shuttle. The Narrows is stop 9, you walk a mile then enter the water. It is very, very rocky. Easy to walk, just slow. We used our water shoes and the sole was not thick enough to accommodate the rocks. Very pretty, crowded. Totally worth it. Again - shuttle!!!
