If you are in Kos, then you should definitely experience its natural spa created by hot springs gushing in a small natural lake in front of Therma beach. The refreshing sea water enters from one side, while the hot water is bubbling. Enter with attention since, once you get used to the high temperature, you won't want to come out. Even though there might be a number of people around you, the sense of relaxation prevails. The place is full of young people too, as it is widely known that hot springs are beneficial for all ages. The entire beach has a rare wild beauty as it is surrounded by large, steep rocks and its coast is full of dark small pebbles.
