Popular with locals, Los Baños Termales de Monterrey is a large public bathing area where you can soak your troubles away. Although the facilities could use some refreshing, a dip in the sulfur-rich waters is quite relaxing. For a more tranquil bath—it can get very crowded on the weekends—you can rent a private tub. Didn't bring your bathing suit on your hiking trip? Don't worry, you can buy (or rent!) one here.
