Hi! I spent a week on the island of Madeira, which is a very calm island which isn't very touristic. It has some amazing and spectacular contrasts and crystal clear waters, rocky cliffs which contrasts with many mountain peaks. Along the coast there are natural pools with salt water, since the island has close to no beacher, there are only about two or three small beaches. You can swim in these pools which are very nice. I recommend it especially for a relaxing trip, no tourist crowds and for those who are not beach lovers.
