Our lady of Rosario Church, Mazatlan

You can go on this tour I went too, last year, called the Rosario Golden Tour and visit this beautiful stone church: Our lady of Rosario Church. It has a gold retable that makes the entire temple shine.
The tour was 45 usd, started at 10:00 a.m. and lasted 6 hours or so. I think on weekends it's available only on Saturday. I made my reservation at Vista Tours, address: Rodolfo T. Loaiza # 214-9, telephone: 914-0187
We visited the Rosario town also and found out about his legends. We visited the ruins of the oldest church, Lola Beltran Museum, The Market, The City Hall, and we stopped for lunch at Tiro de San Antonio where we ate mexican food.
