Corvo is the smallest island of the Azores, only 17 km2 of land surface, and located far west into the Atlantic ocean, north of its big sister Flores.
It’s a huge bump of volcanic rock, consisting of a 2000 m wide and 700 m high caldera with lakes and islets in its centre. The walk around the caldera is difficult and tricky, but a part of it is described as a trail by the local authorities. From the end of the road to the caldera, a trail goes down to its green boggy bottom. On the eastern slopes are fields with cattle and gardens.
