When you're used to the big city life in Chicago, Phoenix is a welcome change of pace. Since the city is in the middle of the desert, expect to see plenty of red rocks and cactus. The terrain is perfect for getting outside and exploring, just remember that there's year-round sunshine. Even on winter days that are below freezing in Chicago, Phoenix is usually right around the high 60's or low 70's F. There are quite a few direct flights available to get you from Chicago to Phoenix, and the flight takes just a little over three and a half hours.
The sunshine in Phoenix makes you want to spend as much time as possible outdoors, and fortunately there are several great hiking trails available. Papago Park is one popular option, while Holbert Trail is one of the best places to see Native American petroglyphs, which are rock carvings. If you want to get in touch with the city's Old West roots, rent a horse for a ride through the desert. Just remember that it gets very hot during the summer in Phoenix so it's usually best to schedule the outdoor activities for the morning before the sun is full-force.
