This is a small uplifted islet close to the east coast of Santa Cruz. It can be gloriously colourful from May to December with leaves of the endemic succulent Sesuvium edmonstonei, or Galapagos carpet weed, turning bright red. A large sea lion colony (one of the largest in Galapagos) resides on this small islet. A small bachelor sea lion colony can be found at the cliff top on the southern side of the island. The territorial bulls, females, and pups are found on the northern side, where land iguanas can usually be seen enjoying the shade of Opuntia cactus trees. The iguanas are also encountered across much of the island. The birdlife on and around Plazas is remarkable varied, including brown pelicans, red-billed tropic birds, swallow-tailed gulls, frigatebirds, Nazca and blue-footed boobies, endemic Galapagos shearwaters, and brown noddies. Small, medium, and cactus ground finches are seen here, too, and schools of yellow-tailed mullet and black triggerfish can be seen from the cliff-top.
