The Golfo Dulce
As one of only four tropical fjords in the world, its bed is rich with volcanic reefs, crevices and caves that have become the breeding grounds for a staggering variety of marine life. It is believed that the gulf is the only place in the world where the humpback whales from both the northern and southern hemispheres gather to breed. Its calm waters have created the preferred home for super pods of dolphins with numbers up to 10,000.
