There are also a number of visitor sites that are close by:

• Bike or hiking tour of the Wetlands (Las Humedales), where you will find dense mangrove colonies and brackish lagoons that are home to pintails and other land birds.
• Visiting the “Wall of Tears”, where prisoners labored in the hot equatorial sun to build a wall of lava rock as part of their sentence back when Isabela Island was used as a penal colony. Now all that remains are black pylons of rocks to memorialize their futile work.
• Las Tintoreras is a great place to take a panga over the clear turquoise water to see a smattering of black and white-tipped reef sharks.
• The Tortoise Breeding Center, run by the Galapagos National Park, offers visitors a chance to see the giant tortoises for which the archipelago is named up close in all stages of life, from egg to adolescent all the way to adult. Conservationists carefully breed and raise these gentle giants in captivity until they are mature enough to be released into their natural habitats.
• For the active explorers, a trek up to the rim of the active Sierra Negra Volcano, with its massive 10km caldera, makes for an unforgettable experience!
