Bartholomew Island

Bartholomew is a small Galapagos Island located 18 miles northwest of the Itabaca Channel. It’s considered one of the best snorkeling sites in the central Galapagos region, a swim at the foot of the Pinnacle Rock and around, its base is the most important deep-water snorkel with many different species of parrotfishes, marine turtles, sea lions and sometimes Galapagos penguins.

Galapagos sea lion

This coastal animal, which is generally playful and curious, measures between 1.5 and 2.5 meters and spends most of its time near the coast. It’s capable of diving to depths of 350 meters and can stay underwater for up to ten minutes. It feeds on a wide variety of fish, but above all sardines, but also octopuses and crustaceans. A single male care for many females and spends much of his time defending his territory from other males. Females have one calf per year; with a gestation time of 11 months. The young of this species have different barks, in this way the mothers can differentiate their young when they return from hunting food. This species is listed as endangered by the IUCN.

Galapagos penguin

Is endemic to the archipelago and is the northernmost penguin species in the world. The majority of its population lives on the Fernandina and Isabela islands. In addition, it is the third smallest class of penguins on the planet with 50 cm. They feed of fish and crustaceans. Their reproduction depends on the availability of food, which is closely linked to the environment, and it is for this reason that climate change constitutes a serious threat to their future. They generally lay 2 eggs that are incubated by both parents for 40 days. It has a life expectancy of up to 20 years.

Sullivan Bay

Located on the southeastern coast of Santiago Island, is an important geologic interest spot. This landscape is composed of lava flows, specifically, the area is covered by Pahoehoe lava flows (Pahoehoe which means in Polynesian language “easy to walk”), this type of lava is rare to the rest of the world but is common to the volcanoes of the Galapagos Islands and Hawaii because they share the same volcanic origin.
