You're heading to Arizona, that's awesome, I've been there a few times and it's such a beautiful state. Definitely check out the Grand Canyon, it's a must-see, the views are just breathtaking. Sedona is another great spot, the red rock formations are incredible and it's perfect for hiking. If you're interested in city life, Phoenix and Tucson have a lot to offer, from great food to museums and cultural events. Monument Valley is also worth a visit, the scenery is stunning and you can take a guided tour to learn more about the history and culture of the area.
