What Travellers Say
Reviews Summary
Visitors find Proval Pyatigorsk to be a historically significant and visually unique site, particularly for its connection to "12 Chairs" and the striking blue cave water. The atmospheric tunnel with music is a frequently praised element. However, the strong sulfurous odor and the small size of the lake are common points of critique, with some finding the experience underwhelming despite the lack of an entrance fee.
"Proval Lake is a karst cave about 18 meters deep, filled with blue hydrogen sulphide water, which has healing properties. It has become a symbol of Pyatigorsk and is known from the novel "12 Chairs" by Ilf and Petrov. Do not expect any particularly pleasant sensations from this place. The smell of hydrogen sulphide is peculiar, it is unlikely to please you. And the lake itself is very, very small, about the size of a garden pond, partially covered with a white film. There are grates installed so that persistent tourists do not fall into this smelly pond. Probably, if you look at this pond from above, the view is more mysterious. The passage to the "lake" is a pedestrian tunnel through the rock."

"Historical place related to Russian poetry. However the maintenance is poor and the natural spring pool could be much cleaner. Still is a nice place to visit."
Stepan Syrkhaev
"Famous historical sightings of the Pyatigorsk, walking there is also can be a nice active because you can stop by other places, drink spring mineral water and by souvenirs"
