Marielas Islets are a group of small rocky islands on Elizabeth Bay, home to a big colony of penguins. Because of the cooler waters, in this area you can find the largest colonies of penguins and also the largest marine iguanas. The site can be explored only off a dinghy ride, and you can actually enjoy nature without engine noise. The islets are rich in wildlife, you can easily spot green turtles and rays in the water. On the shores and the mangrove forests, blue herons and pelicans are often seen.
