Downtown Phoenix’s hottest sports fixture is this immense masterpiece of engineering. Home to the Arizona Diamondbacks, the facility seats more than 49,000 guests. It features a retractable roof that exposes the natural turf to sunlight.
During the intense heat of the summers here, this air-conditioned ballpark cools down the heated competition. Other highlights of the building include a 385 square-foot pool and spa that can be reserved for private parties. Year-round tours are available and last a little more than an hour.
