Kiev has a wide selection of beaches & Beach Clubs, located either inside the city (Hydropark) or towards the south (Maja4ok area).

The beaches can be separated into two categories:
1.) free beaches where everybody can go, lay down and relax and
2.) Beach Clubs which take an entry fee but provide sun beds, some of them towels, F&B

Beaches of the 1st category can be found plenty, either normal or nudist, mostly. Bring your own towel, drinks and snacks and enjoy the sun and a swim in the Dnepro river (yes, no problem to swim inside, there're even fishes). Be aware that there aren't sanitary rooms etc., it's just wild beaches.

There're some Beach Clubs and the one to select very much depends on your pocket and style.

Approx. 20 km towards the South of Kiev is the Kiev Yacht Club, Maja4ok. There're two nice beach Clubs of one is "Maja4ok" Beach Club (don't mix with Maja4ok restaurant & Yacht Club which you'll pass first). Maja4ok is separated into two areas, a) standard at 100 Grivna/day with plastic sun beds and not too much space and b) the VIP area at 200 Grivna/day with much more space between the sun beds, shower, wooden sun beds... Maja4ok serves nice food, drinks at the beach. Maja4ok doesn't have a swimming pool at all - so there's no option to swimming in the Dnepro.

Inside the city (Hydropark) you mainly have two Beach Clubs:
1.) OLMECA Beach Club offers a stunning view towars Dnepro, Lavra and Rodina-Mat.
The access (incl. swimming pool use) with a sun bed & towel, Wi-Fi internet usage etc. is 300 Grivna/day or for a bigger round bed 800 Grivna/day.
The pool is huge, there's music all day, Go-go dancers, food, shisha (water pipe)... It's the hot-spot of Kiev during day time in summer. You'll have all the nice cars in front, all the beautiful & rich people of Kiev. So be prepared for the day-time fashion show of Kiev. Bills can really add up here, especially when you have food & drinks (you can't bring your own, they're checking bags!).

2.) Bora Bora Beach Club which also offers a swimming pool (but far smaller), DJ, huge sun beds which you can share (max. 4 persons at 400 Grivna/sun bed).
