The Gheorgheni Basin (Romanian: Depresiunea Giurgeului) is located in Romania, in Transylvania, in Harghita County, between the Gurghiu Mountains and the Giurgeu Mountains, on the upper reaches of the Mureş River.
The Gheorgheni Basin is one of the coldest places in Transylvania, the average temperature in January drops to -9 ° C. Heat inversions are almost constant, with frequent fogging, early ice formation, and late spring. The cold climate is indicated by the fact that the pine forests descend from the mountains all the way to the bottom of the pool. Climate and altitude have a decisive influence on the climate.
The waters of the basin belong to the Mureş catchment area. The Mureş originates on the border of Izvoru Mureșului, on the side of the Fekete-rez mountain. In the basin, the Mureş has created a strongly meandering floodplain, which corresponds to the character of the lower section. It crosses the basin in a north-south direction, while embracing a number of wide-water streams.
The Basin has one city (Gheorgheni) and 10 villages: Ciumani, Ditrău, Joseni, Lăzarea, Remetea, Suseni, Voșlăbeni, Chileni, Valea Strâmbă and Izvoru Mureșului.
