A completely new environment was explored today as we arrived to Santa Cruz Island. We began with visits to the Charles Darwin Research Station, and the Giant Tortoise Breeding Center, which together have been working to restore native populations of tortoises in the wild. After spending some time in town, observing the bustling day-to-day of the largest human population in the islands, we headed up to the highlands of Santa Cruz, to see the changes in the scenery and vegetation zones as we gain altitude.
