Isla Bartolomé (Bartolomé Island) is one of the most spectacular volcanic landscapes in the Galapagos, full of parasitic spatter cones, lava flows, Galapagos penguins and lava lizards.
It is a relatively new island in the archipelago and traces of its volcanic past can be seen everywhere, as evidenced by the amazing lunar-like landscape.
The Pinnacle Rock is one of the most photographed sites in the Galapagos – an abrupt jag of rock protruding from the earth like a tooth, while nearby two golden bays back onto each other.
You can hike to the top of a once-active volcano here (360 wooden steps), and enjoy superb views across to Sullivan Bay, on nearby Santiago Island. If you are in luck you might catch a glance of the Galapagos Hawk here. You also have the opportunity to go snorkelling with plenty of tropical fish, starfish, white-tipped reef sharks, rays and hopefully penguins.
On Santiago's eastern coast sits Bahia Sullivan, also known as James Island. Here you walk on Pahoe-Hoe lava, from an eruption that occurred in 1897, and witness the colonisation of plant species since the last eruption. Hopefully see some marine iguanas, Sally Lightfoot crabs, sea lions, finches, turtles, sharks and penguins. On a walk, your guide will explain the geological history of the islands.
