Datcha is a wonderful and very secluded place in a small bay.I recommend driving there in a rented car and spending the whole day.There are almost no tourists and a lot of local flavor.
First of all, there is peace in the air. If you want to lie down on a sunbed in a business, you can find it. If you don't want a business. When you take your drink from the grocery store and open your folding chair, everywhere is your beach. You can also make the same beach your night spot. The sea is very beautiful everywhere.
