The largest settlement area, offering the most services in the Galapagos, Puerto Ayora is a port town situated along Academy Bay on Isla Santa Cruz. Most yachts offering cruises of the Galapagos hail from Puerto Ayora. Also home to the National Park Services and the Charles Darwin Research Station, it is the hub of tourism in the islands. Puerto Ayora is far from the bustling cities on the mainland. The bay is full of sailboats, sea birds fill the air and marine iguanas line the shore. Though a thriving center of commerce people enjoy a laid back island attitude. Most travelers to the Galapagos will include a visit to Puerto Ayora during their trip. Most cruises include a visit to the Darwin Station and arrange free time to explore the town and shop for souvenirs. This may be the only opportunity to souvenir shop in the islands. Stores carry everything from t-shirts to jewelry, post cards, books, beach ware and ceramic items. The grocery store offers the opportunity to stock up on any forgotten items, snacks, beverages, or other items you might desire on board. If you are in need of additional money, the Banco del Pacifico offers cash advances on Master Card. They also offer a Cirrus ATM machine, though it does not always work. Puerto Ayora offers options for visitors who prefer to sleep ashore or extend their stay in the islands. There are a variety of tours available allowing visitors to design their own Galapagos experience including day-trips to a number of the islands, dive trips, kayaking, highland tours, hiking, mountain biking and horseback rides.
