im planning to go on vacation next spring to eastern europe and russia. what are good sites to see?

im going for spring break with my family. a friend told me Ukraine has nice beaches. but i dont know what else to do while im gone

if you are going for sun and beaches Ukraine is not the right place ma friend....But St.Petersburg and Moscow are nice cities for museums and sightseeing...If for beaches and like i would recommend you Turkey Antalya..really cheap and lots of fun...See ya!

St. Petersberg - lots to see - Museums etc.
L'Hermitage, Kirov Ballet.

I DON'T recommend you to go to Ukranian beaches. Believe me Black sea isn't the best place to spend time there. More or less nice beaches are at Finnish Gulf, near Saint Petersburg, but in spring it's too cold to swim anyway. I am from Moscow myself and been to SPb millions of times, if you have any specific questions - PM me.

Castle Bran in Romania.

The Danube river

Go hiking in the Carpathians
