El Rosario, a small town about 50 miles south of Mazatlán, is famous for the altar in the town church which is said to be worth over a million dollars. The alter alone makes a visit to El Rosario worth the drive. El Rosario was once the richest town in Northwest Mexico because of the local mining operations. This small town was the home of the famous Mexican singer, Lola Beltrán. They have built a small museum in her honor although the museum is open only sporadically. You might want to do a little shopping for pottery, furniture or leather products, all of which are produced locally.
