San Cristóbal has a number of sites that are easily accesed by land. Just past the Cerro San Joaquin trail junction is Laguna El Junco, one of the premanent freshwater lake in Galapagos. Beyond El Junco the road heads east and south to La Galapaguera a large walled enclosure built to provide a secure location for the San Cristobal Tortoise. Not far beyond La Galapaguera you come to the end of the road, at Puero Chino. This small, sheltered bay on the south side is a popular swimming and snorkelling spot.
