Surfing Puerto Escondido, The Mexican Pipeline, Everyone’s heard of the place and many have given it a try. But how much of the Escondido legend is true and how much is myth? The truth is that Puerto can match its reputation, if you are willing put in the time it takes to know the place.First off, the waves. The surf is seasonal, varying from small to medium in size during the dry season (November to April), and from small to big during the rainy season (beginning in early May).
