Coos are lunar landscapes, peat bogs and tiny lakes, where, as it may seem at first glance, water does not stop boiling for a minute. In fact, the water here does not boil and remains cold: in this tectonic depression, where the reserve is located, mineral springs come to the surface, emitting carbon dioxide through myoffices - shallow craters. In places of dried up sources, the ground is covered with yellow or white salts. There is also a zoological station and two museums in Soos. One shows the local flora and fauna, the other - prehistoric animals in the form of models of dinosaurs and pterodactyls.
