Isabela is the largest of the Galapagos Islands, with over half the total land area of the group. The island has been made from six huge volcanoes, connected by miles of lava which is very difficult to travel over and impossible to farm.

This is probably why Isabela has remained relatively sparsely populated, and has a bit of a "Wild West" feel to it. However, it is still home to about 1,000 people. Most of the families are involved in the fishing industry.

As well as the main town and port, Puerto Villamil, there is a small agricultural settlement at Santo Tomas on the side of the Sierra Negra Volcano.
