Isla Cerralvo (Spanish: ['izla se'ralbo]), as is commonly named, whose official name is Isla Jacques Cousteau (French: [ʒak kusto]; Spanish: [ʝak 'kusto]), is an island located off the Cerralvo Canal coast near La Paz, Baja California Sur, Mexico. It is 18 miles long with a land area of 136.498 km² (52.702 sq mi), and is the ninth-largest island in Mexico. It is part of Municipality of La Paz. The island peak comes to 2,100 ft (640 m) and the ridge line runs north-south with many small streams draining east to Sea of Cortez and west to Cupalo Canal. There are many steep bluffs on the eastern sides and many sandy beaches and points on the west side. There is abundant marine life surrounding this island due to underwater topography and ocean currents. Virtually all local marine life must migrate past the island and water visibility goes up to 30 meters making it a prime location for big game fishing. There are abundant golden grouper, marlin, sailfish, swordfish or broadbill, and other game fish in Cerralvo Canal waters. Views from island at dawn and sunset are very lively and filled with color.
