The spectacular beaches are primarily the remains of gastropods, corals and coralline red alga.
The geological history of the island includes the rise and fall in sea levels over thousands of years, and the growth of the volcano — both responsible for the island’s beauty.
Coronado Island has seven spectacular beaches for camping; it is a popular area for fishermen to rest after a long day journal, or for other visitors to spend the day in extreme relaxation while enjoying the magnificent views.
The island has several attractive sites for SCUBA diving and snorkeling, since its volcanic formation has generated intricate rock formations at the edges and below sea level, mainly in the Northeast side where the small caves and walls provide refuge for hundreds of fish.
Visitors can also visit “La Lobera”, home of a colony of playful and noisy sea lions. This animals often allow visitors to swim close to them, provided it is not mating or birthing season. At that time they are very territorial and could be considered dangerous.
