During the years, the dissolved minerals created a kind of fountain from which the water streams up to 5 meters into the air. The geyser has several balconies that flow over into 30 to 40 basins at the territory of approximately 30 hectares.Those basins form a specific ecosystem with small birds and fish.

Rainbow colours originate from various water minerals and react with the air oxygen. It is covered by thermophile algae, high temperature tolerant microorganisms.
Because the geyser Fly is located in the private piece of land, and fenced by a high barbed wire and a high gate, it is rarely opened for the public but can be seen from the road.
Also, in this area, there are another two geysers, that appeared similarly as the geyser Fly, and one of which is 1 meter high and resembles a small volcano and the other is conic-shaped and of the similar size as Fly. Also, there is another interesting fact relating to these geysers – they are constantly growing.
