Today we visited Santa Cruz Island, the most populated island of the archipelago. Our first visit was to Charles Darwin Research Station, where we learnt about the important conservation role that this institution plays in coordination with the Galapagos National Park Service. Later, we moved to the highlands of Santa Cruz, to visit an amazing lava tunnel and a sugar cane farm. After a delicious lunch in the highlands, we explored a lush forest where Galapagos giant tortoises can be found on their natural habitat. At night, a local group of musicians and dancers visited us onboard to celebrate a great day with a nice party.
