On Friday we did the full day trip to Furnas, definitely the best geothermal site. As a family we were fascinated by the Victorian equipment still being used in the tea plantation we visited in the morning. Seeing the fumaroles and eating the food cooked in them was a real novelty. We swam in the pools in the afternoon, which was great again. These ones had much more iron in them than the ones at Lagoa do Fogo so it was important not to have our 'best' swimming costumes and towels on that day as they got a bit stained. - Sally Smart April 2022
