Ixtapa is a beautiful sea resort in the Pacific. It is near to Acapulco but it´s cleaner, quieter, safer and more beautiful. I suppose Ixtapa is not so famous abroad as Acapulco, Los Cabos or Riviera Maya but it´s really very nice place. Nice beaches, clear sea, amazing vegetation. Highly recommended!
