On my way to Yosemite I was able to spend one evening and morning at Arches National Park outside of Moab, Utah. Arches was an awesome experience to see the natural arches created by erosion. It was also a great place to see the amazing rock formations. Expect to hike to see several of the arches. Some are easy and some are more difficult. Unfortunately, due to time constraints I was unable to do as much hiking as I wanted. I do recommend starting early to avoid the heat of the day and the crowds. If you have time take in a sunrise or sunset.
