One of the oldest resorts on the Pacific Coast, Mazatlán, known as the “Pearl of the Pacific,” has earned the reputation as one of Mexico's most popular and active beach communities. It's a bustling commercial port — Mexico's largest — renowned for its fine sport fishing, clean beaches, sunny climate, excellent dining, and nightlife. It's also known for its billfishing tournaments and for its succulent shrimp — and, of course, for the best Carnaval in Mexico, after Veracruz.
