Caution! If you are traveling with an RV AND you are going through ZION NATIONAL PARK there are hight and length restrictions (for good reason) BUT they are not displayed prominently on the west side going east. So, if your headed east going through ZION NATIONAL PARK with a 5th wheel trailer or a trailer over 25′ or a cab over camper, or a motorhome, you probably can’t go through the park because of VERY sharp turns and a very long tunnel. So, take my advice on this one and research this before trying to travel through. It’ll save you 3 hours of time, 100 miles of driving and the extra fuel costs.
