Bartolomé Island

Bartolomé Island (Spanish: Isla Bartolomé) is a small volcanic island in the Galápagos Islands, just off the east coast of Santiago Island. It is one of the younger islands in the Galápagos group and was named after Sir Bartholomew James Sulivan, a friend of Charles Darwin who sailed with him on the HMS Beagle.

The island covers about 1.2 square kilometres and features the remains of an extinct volcano, with colorful red, orange, green, and black volcanic rock formations. Visitors can hike a 114-metre trail up the volcanic cone for great views of the surrounding islands.

Bartolomé is well known for Pinnacle Rock, a tall rock formation that rises above Sullivan Bay. The bay is a popular place for swimming and snorkelling, where people can see Galápagos penguins, marine turtles, small sharks, and many tropical fish. A cave behind Pinnacle Rock is home to a group of penguins that breed there. The island's beaches are also used by green turtles for nesting and by herons. Unique lava cacti grow in the island's lava fields.
