One of two small islets, South Plaza island houses a rich diversity of wildlife and vegetation. After passing a large colony of sea lions and ascending the slopes, you may catch a glimpse of swallow-tailed gulls, Nazca boobies, red-billed tropic birds, frigates or the rare lava gull. The ground is carpeted in Sesuvium, which transforms from bright red in the dry season to a vibrant green in the wet season, and land iguanas crowd around towering prickly pear cacti, waiting patiently for their juicy fruits to fall.
