Devil’s Crown is a volcanic formation located off the coast of Floreana Island in the Galápagos Islands, Ecuador. Visitors can snorkel or dive to observe a range of marine life, including reef fish, rays, sea turtles, and, occasionally, sharks, within the circular rocks of the former crater. The site was once a volcanic cone that has eroded over time, leaving a ring of jagged rocks, and its waters are known for both rich biodiversity and sometimes strong currents, which can make swimming challenging for inexperienced visitors.
