The trail around the rim of Caldeira is the highest trail on Faial. Caldeira is a very unique volcanic collapse crater because the high altitude allows for a geological interpretation of most of Faial’s characteristics. The interior of the Caldeira is one of the most important nature preservation sites in the Azores. This trail also provides us with the opportunity to learn about the native flora because some species have adapted to live on the rim that is exposed to high winds. Our guides do not advise you to visit on a rainy or windy day, but on a clear day you can virtually see all around the island.
