Guide of the Azores – What to visit, what to eat and where sleep


The Azores evolved from volcanic eruptions over many millennia; and all round the islands are examples of curious volcanic phenomena. There are rounded craters or“caldeiras”, often filled with lakes, plus caves and deep tunnels formed by the eruptions. Ancient black lava covers many surfaces on the islands, ranging the from shiny obsidian to soft and porous lava, sometimes bubbling with steam from hot springs.
