20. Bryce Canyon National Park, UT

Bryce Canyon, like many other sights in Utah, is amazing and unique. It has some of the best air quality in the world and very little light pollution, so camping overnight offers the perfect opportunity to see the stars. The park is bordered by meadows and pine and spruce forests, which are home to a large variety of wildlife.The canyon consists of limestone rock which has been eroded by rain and frost, and it now shows off a billion different shades of red in its bizarre and original shaped features: slot canyons, windows, fins, and spires, all collectively known as "hoodoos". The hikes through this park are more memorable than most, and the views are equally exciting, especially at sunset. Ask the park rangers “hoodoo you get to (name a location in park)?”, and they will be most helpful with a detailed response and polite laugh to humor you (they really do think it’s funny though… guaranteed... go ahead, try it out).
