Today is the first full day of our expedition in the Galapagos Islands aboard National Geographic Islander II, and we visited the most populated island, Santa Cruz. There are around 20,000 people here. In the morning, we took buses up to the highlands to visit Los Gemelos, also known as the Galapagos Twin Craters. This area is surrounded by a beautiful scalesia forest. Later in the morning, we went to Rancho el Manzanillo, where the giant tortoises were waiting for us. In the afternoon, we got to see the Darwin Center, where the most important research happens in the Galapagos Islands.
