He was one of the earliest to explore the shores of Mexico. He left Cuba with four ships in April 1518. According to Hernán Cortés, 170 people went with him, but according to Pedro Mártir, there were 300 people.
After rounding the Cape of Guaniguanico in Cuba, he sailed along the Mexican coast and arrived on May 1 at the Tabasco region in southern Mexico. Río Grijalva (Mexico) was named after him. Bernal Díaz del Castillo wrote about the travels of Juan de Grijalva in his book.
He died in Nicaragua in 1527.
