On the coast of Michoacan, Maruata has been a mecca for some time now. The big Parties are Christmas and Easter. No hotels, only camping. Lots of drums and other music. The locals are Nahuatl Indians, and extremely friendly. Best beach on the West Coast of Mexico.
Long an escape for the gringos, still an interesting country to visit from Baha to the Yucatan, lots of places to explore and hang out.
