During the cold months, the Green Lake park in Tragoess is completely dry and a popular hiking place. However, as soon as the sun comes out in spring, the mountain snow melts and fills the park with ice-cold water. Interestingly the water takes a green hue on account of the grass and foliage beneath. The water level rises from 1 meter up to 10-12 metres in some parts. It reaches its highest point in June and at the end of July, the water begins to recede. Green lake used to be a popular site for divers during the spring and summer floodings. However, from January 2016, diving has been banned here due to concern for the fragile ecosystem of the lake.
