Galapagos Islands: Days 6-7
On Isabela Island: hiked up Sierra Negre to the crater and the nearby recent lava flows one day and took a day long boat excursion around the western tip of the island in search of flightless cormorants, penguins and fur seals, as well as explore the coastal lava tunnels and go to another site for snorkeling with sea turtles and seahorses.
