Varna is an amazing city and it’s worth to visit (especially in the summer).
Varna is a seaside resort in Bulgaria on the Black Sea. We went here as part of our river cruise and took a boat ride on the Black Sea. The resort city looks very different then most of the other cities in Bulgaria with most of it's economy based on tourism. It has a long summer which helps the tourist trade.
Don't miss Seaside Park and then go down to the beach to some great restaurants for the sunset.
Varna was the cornerstone of the Red Riviera in Soviet days. This town on the Black Sea and the Orient Express has a handsome old town center and several nice beach resorts. In the summer time the Black Sea is warm and there's plenty of sunshine.
