I was in Mazatlan in October 2006 and took a van tour with Raul of Mazatlan tours. We found both the tour and Mazatlan to be a great experience. Raul was a GREAT tour guide! I highly recommend his tour. He was one of the most knowledgable tour guides I have ever had anywhere. On the way back to the ship, he even stopped at a local firehouse so I could see some of the local equipment and meet some local firefighters!
Mazatlan was, without a doubt, one of the highlights of our Mexican Riviera cruise!
