Bryce Canyon is one of the most beautiful and photogenic national parks you can visit. I highly recommend hiking the Queens Garden Trail; the views from inside the canyon are absolutely amazing. It is a moderate hike with some steep sections, so be prepared. Just keep in mind that parking spots fill up fast, and parking at the Visitor Center is limited to a maximum of 1 hour as far as I remember. I recommend starting either early in the morning or later in the evening to avoid the harsh midday sun, which can really wear you out. Don't forget to carry plenty of water!
