Situated on Sao Miguel Island, Furnas, resting within the lush valley of the same name, is an enthralling destination famous for its hot springs. The town is one of the largest natural spa centres in Europe and features several phenomenal calderas decorated by geysers, hot springs, and mud baths. Vila Franca do Campo and the Lagoa das Furnas are the primary must-sees for the full Furnas experience. An unusual addition to the scene is the ‘cooking holes’, where meals can be cooked underground. Hike around the stunning Furnas Lake to the beautiful Miradouro do Pisao (a viewpoint providing spectacular vistas), and look out for saffron finch and pink tern. Pop into the impressive Gothic church next to the lake, or wander through the pretty Terra Nostra Gardens. The excellent golf course, with its numerous Japanese trees, is another highlight.
