The Coronado Islands (Islas Coronado or Islas Coronados in Spanish) are a group of four islands off the northwest coast of the Mexican state of Baja California. The islands can be seen from Tijuana, Mexico or Imperial Beach and other shoreline areas of San Diego, California.
Battered by the wind and waves, they are largely barren and uninhabited except for a small military detachment and a few lighthouse keepers. The islands lie between 15 and 19 miles south of the entrance to San Diego bay, but only 8 miles from the Mexican mainland. The Coronado Islands are a Mexican wildlife refuge; visitors may anchor, scuba and snorkel, but trips ashore are not allowed.
- North Coronado has no bay, but boats can anchor on a jetty on the eastern side.
- Pilón de Azúcar is very hard to land on. It has little vegetation but there is a flock of birds that rest here.
- Central Coronado has a rocky peak with a heap of cactus and scrubs near the summit.
- South Coronado has the only bay of the islands, called 'Puerto Cueva'. It has a lighthouse on each extreme.
Coronado, since the 1980s also mistakenly known as Coronado Island, is a resort city located in San Diego County, California, across and around San Diego Bay from downtown San Diego. Coronado lies on the geographic combination of an island and a tombolo connected to the mainland called the Silver Strand. Coronado is a tied island, connected by a tombolo. In 2012, Dr. Stephen Leatherman, Director of the Laboratory for Coastal Research, ranked Coronado Beach as the best beach in the United States.
