I was in Pico in April 2017 and did an Island tour. The driver Duarte was a nice local guide that knew everybody on the Island. He did many stops that were not aritten in the program and we had some nice wine tasting. Its really a nice trip and you visit places that you would not find on your own.
One of the highlights of our Pico stay was the tour in the highlands. We saw soooo many cows, flowers, and landscapes. We saw at least 5 rainbows. A highlight was a little cave hidden in a cowfield and the walk at the little crater. A wonderfull day and a professional driverguide that told us so many things of the Island.
