The only way of accessing to this venue is by boat. Those islands house a huge quantity of marine species. You can go through caves, isolated rock picks where some sea lions are sleeping, you will also see the flight of Guanay cormorants and pelicans above your head. In the sea, you could see some dolphins and Humboldt penguins racing. Entire colonies of pink flamingos live the day up on the island. This is a very special excursion thanks to the incredible density of biodiversity.
