Bartolomé Island (Spanish: Isla Bartolomé) is a volcanic islet just off the east coast of Santiago Island. It is one of the “younger” islands in the Galápagos archipelago. This island, and Sullivan Bay on Santiago island, were name after naturalist and lifelong friend of Charles Darwin, Sir Bartholomew James Sullivan, who was a lieutenant aboard HMS Beagle.
With a total land area of just 1.2 square kilometers (0.5 square miles), this island offers some of the most beautiful landscapes in the archipelago. The island consists of an extinct volcano and a variety of red, orange, green, and glistening black volcanic formations.
Bartolomé has a volcanic cone that is easy to climb and provides great views of the other islands. Bartolomé is famous for its familiar Pinnacle Rock, which is a distinctive characteristic of this island.
It has two visitor sites. At the first one, one may swim and snorkel around Pinnacle Rock; the underwater world there is really impressive. Snorkelers are in the water with the endemic Galápagos Penguin, marine Turtles, White-tipped Reef Sharks, and other tropical fish. The bay is also an excellent place to go swimming. The twin bays are separate by a narrow isthmus.
The endearing little Galápagos Penguins are often seen, and a small cave behind Pinnacle Rock houses a breeding colony. Seasonally, Bartolomé is the mating and nesting site for the Green Turtle. With the Herons, they make use the gentler beaches. The Galápagos Lava Cacti colonize the new lava fields.
You will experience one of the best snorkeling sites in the world! Truly an amazing and unique experience
Small islet located near the southeast coast of Santiago Island. It is an islet made up of a splashing cone (lava ejected in the form of drops and falling near where it erupted, which forms an incline cone) that makes up the summit and many lava tubes that descend toward the coast.
On the western side you can see lava formation pillows, which are an indicator that the flows were form under the sea and have been raised to the outside, which is why coral heads are found on the lava. It is shaped like a Chinese hat (thereby generating the name Sombrero) when viewed from afar. It presents coastal vegetation of plants tolerant to salt water, Palo Santo, among others. We can find Lava Lizards, marine Iguanas, the vividly colored Sally Lightfoot Crabs, coastal birds and sea lions of Galapagos are part of the fauna that you can find on this island, as well as Penguins, Hawks, Iguanas and Sea Lions. On Isla Sombrero Chino you can snorkel and swim in the cove, frolic with the Sea Lions and you can also see Falcons and interesting lava flows
