A true resort town along the Pacific, Mazatlan is about sport as much as it is about relaxing amid the surf, sun and sand. Big for fishing, many come here to reel in monster catches including: sea bass and corvina. Snorkeling and diving are also hugely popular in Mazatlan. The city is also a great place to visit for those who want glimpses of old Mexico. A historic downtown boasts a famed 19th theater, the renowned Immaculate Concepcion Basilica as well as a number of museums worth checking out.
