Zion Naitonal Park is located less than 75 miles from Bryce Canyon National Park. We were told early on in our planning, not to take the RV to this park. So we scheduled extra time at Bryce so we could take a day to visit Zion. As a side note, we visited Zion on the 9th and on the 11th , monsoon rain hit the park and the cell remained over the park for days. Some campers were stranded and most of the trails were closed. By the 14th, the park closed.
There were two tunnels to go through, one short –
and one long and very dark tunnel. If a large RV needs to go through the longer tunnel, they shut it down to one lane.
It would be pretty hairy passing a big RV in this.
The ride to the park entrance was beautiful:
This park was different from any of the ones we have visited so far. You are not permitted to drive through the park and must use a free shuttle service. You must park your vehicle and yes, pay for parking. You also pay an entrance fee to the park. We purchased an annual pass. If you plan on visiting more than one park- get the pass. The pass was $69.00 and most entrance fees are $30.00. The park has a scenic drive with multiple overlooks and trails. It was very difficult to see anything from the shuttle bus and the bus will not just stop for you to check out an overlook. You would have to wait for the next shuttle to pick you up.
From the visitors center we did a short, but very steep hike to what was described as an archaeological site. They asked that you do not disrupt the ruins and artifacts. The area up top was not very big at all. We looked and looked -there were no ruins or artifacts. What we did see was the parking lot below. 
There were some nice views from the top:
Terri and I decided to take the shuttle to the end of the scenic drive then, on the way back, we would stop at the overlooks and wait for the next shuttle. While waiting for the shuttle, we made a friend:
We would run into many of his cousins throughout the day. None of them were shy. By the time we reached the end of the scenic drive, I had Terri convinced to try Hiking the Narrows. This is the most popular part of the park. First you must hike a 2.2 mile Riverside trail to access the Narrows. This is a river that runs through a narrowing canyon. It was a nice hike along the riverside.
There was a steady stream of people going to and coming from this popular attraction while the skies were thickening with clouds.
Walking the riverbed and through the water was really something. We used our trekking poles to help with the slick river rock:
We started to hear thunder and high tailed it out of there. The rain was light at first, but by the time we reached the shuttle stop, it was torrential! This was the beginning of the rains that have flooded Zion and caused them to close the park 2 days ago.
