From late March to July Cozumel is visited by streams of Blue Marlin following the warm waters of the Gulf Stream into the area. While the average Blue Marlin here tends not to be as big as the Pacific variety that visits the west coast of Mexico, they still offer an exciting and very athletic fight and are certainly not to be sniffed at. Don't miss the exciting Rodeo de Lanchas Mexicanas tournament to catch some of the best billfishing action in the area every May.
