Campground

Can stay at a nice hotel for less than what some of those parks are charging.

Here at Tres Amigos RV Park on Stone Island/Isla de la Piedra rates for one week start at about $120.00USD per week. You can stay a month for $350.00USD. Front row sites are full and are more expensive. You can be in Centro in less than 15 minutes.

Photos are available on my blog.

500 USD to The high end at Marosa 1200 USD ocean front..

Last chance for Marosa as I heard the Lady that owned the land has passed away... Rumor has it the kids visited the real estate office before going to the the undertaker.

How much does it cost to stay at one these places?

The best one is Mar Rosa, right on the beach and close walking distance to everything.

If you like the more relaxed beach life come join us at Tres Amigos RV Park on Isla de la Piedra. Good water, power and hookups and great people. The road in is rough, just idle your way in and sip a coldee. We have trailers, 5ers and Class As and Cs here. Mazatlan is just a panga ride across the harbour. The beach is 8 miles long and mostly undeveloped. One of the few places in the world left like it. Come and see before it too is ruined.

Since You haven't been before I would suggest that You try to get in to Mar-A-Villas RV Park. It is an Older Park ,but is right on the Beach at the North End of Mazatlan.
You really should check the Church Book for suggestions. The Travelers Guide to Mexican Camping!
