Furnas is a hot springs location in the inner island. The local resturants use the hot spots to cook a delicate dish of various meats, seafood, and vegetables. In the early morning, pre sunrise, they place the pots in the pre-dug holes. They let them cook all morning and remove them just before the lunch hour.
We got to enjoy this one-of-a-kind meal at a local restaurant- the pictures show the exact pot we ate from.
Furnas area also has a volcano lake near by that made for some gorgeous views.
Also near furnas, is the famous church on the hill. If you are able to climb the steps, I recommend it. Great views!
