Urbina Bay is a place of great geological importance for an unusual event that took place there as recently as 1954. A powerful earthquake with a magnitude of 6.5 on the Richter scale caused the coastline to uplift, exposing the ocean floor. Today, Urbina Bay has become an extension of Isabela Island and is filled with abundant plant and animal life. Search for the gentle Galápagos giant tortoises along your walk. Keep an eye out for land iguanas in the underbrush. Farther along the trail, marvel at the exposed coral reef that was once part of the ocean floor many years ago.
