One of my favorite parks to tour in my Free Spirit is Bryce Canyon National Park in Utah. I visited in mid march which meant that there was still snow on the trails but it was not crowded at that time of the year and there was plenty of parking. The views are incredible. One has to see the rich red and orange colors of the hoodoos to really appreciate them. I wanted to stay longer but a winter storm was on the way which ultimately dumped several feet of snow on the mountains.
