Sauna? Hammam? Nope. Russian banya is what you are looking for. 
A tradition that dates back centuries gives a great possibility to get to know Russian culture better and feel the warmth of the camp’s hospitality. Banya is a perfect way to cheer up and chill out at the same time. Think of enjoying this exotic experience right on the lakeside after various activities you are proposed. What else? Soft and smooth skin, regular blood circulation, keeping fit – that’s what you get besides having fun. 
Last but not least: have you ever heard about bath brooms? No need to google - come and try it.
