I really liked the Batumi beach on New Year's Eve :)! The sea is always pleasing, the sunset, the incredibly beautiful sky, the sea air. Even in winter (it was +14), you can enjoy the sea.
The water may be cleaner than in Batumi, but it is not clean;) the entrance is with large stones, in places there are hidden breakwaters in the water. It is beautiful next to the rocky hill.
There is a good beach, the water is cleaner than in the city center and there are fewer people. There are free changing rooms and showers. It is very beautiful around, because there is a botanical garden nearby
