Isabela Island forms over 50 per cent of the total land mass in Galapagos. We had the opportunity to explore four visitor sites on Isabela. Even though they are on the same Island and not far from each other, they are very different from one to another. This Island has the best places to see one of the largest populations of marine iguanas, penguins, cormorants, hawks, and finches that are endemic to Galapagos only.

Urbina Bay and Tagus Cove, Isabela Island
Isabela Island holds half of the land mass of the Galapagos Archipelago. Towering over the rest of the island chain with its massive shield volcanos, it is a diverse environment for numerous species. A morning visit to Urbina Bay shows us the unique and young geological formation of an uplifted area. A couple of square kilometers of intertidal zone was uplifted in the early 1950’s, in certain cases over four meters out of the ocean left high and dry. Vegetation has taken over the area since the uplift, with Galapagos giant tortoises and land iguanas roaming the area freely. We encountered over nine tortoises using our path for easy transportation. Yellow warblers, Galapagos mockingbirds, and Darwin’s finches provided an interesting soundscape. The afternoon brought us to Tagus Cove, with its historic graffiti written on the cliffs, some dating back to the early 1800’s. In the water or exploring along the coast, we encountered Galapagos penguins fishing among flightless cormorants, with the occasional plunge diving pelican. A heavy rain shower provided a cool, crisp feeling to the atmosphere as the sun painted the late afternoon sky among the clouds. It was another fascinating day exploring these incredible islands.
