The survey is timed to coincide with International Friendship Day, which is celebrated on July 30.
"Russians most often go on vacations with friends to Sochi and Yalta. In second place there is Gagra. Kazan and Moscow got the ‘bronze’ in the rating of the best cities for friendly get-togethers," said the experts.
The TOP-10 also includes Altai, Kaliningrad, Lake Baikal, St. Petersburg and the Tver Region.
