Limestone mountains Aktau is a geological museum under the sky. This is one of the most interesting and spectacular objects of tourism in the State National Natural Park “Altyn-Emel”. In Kazakh it means the White Mountains. Mountains seem white only from afar. In the canyons of the mountains one can find naked multi-colored dome rocks, towers composed of coloured layers alternative with dry canyons, filled with calcite crystals. Landscapes change constantly – bastions, towers, small towns, inaccessible castles and canyons, there is no end to them.
