Just off the coast of La Paz, Espiritu Santo is the crown jewel of the Sea of Cortez and a UNESCO World Heritage Site. Espiritu Santo has the most intact ecosystem in the region - It offers views, activities, wildlife above and below water and always delivers with its ability to love and share with us. Sea of Cortez is world renowned for the variety of fish species. It is a mecca for behaviorists. Whether it is to see all the colors, observe their behaviors or enjoy the aquatic life, Sea of Cortez has something for everyone. Fishing hit it hard but now it has come back to life. Whale sharks, sea lions, humpback whales and the huge schools of endemic fish are as abundant as ever before.
