The main attraction. Beautiful at sunrise, the 3 mineral lakes at the top (in the craters) change colour with the changing of the volcnoes activities. The lakes change color completely from time to time. In the national park you can see a table of what color the lakes were for each year going back 20 years. It is impossible to take the three lakes altogether in one frame as displayed on postcard from the ground. Should use drone or sometimes there are chartered air planes fly over the three lakes.
