Estonia offers incredible history and many of the same draws as more popular European destinations like Copenhagen. Take a medieval tour of the city, stroll the cobblestone streets of old town, visit the Kadriorg Art Museum, and then check out the incredibly exciting nightlife.
"Lesser-known European cities are becoming more mainstream to travellers with the increased accessibility," Anna Fawcett, global head of marketing at Topdeck Travel told POPSUGAR. "Destinations like Tallinn offer much of the same charm that Americans cherish most about what they've already seen in Europe — like everyone's favourite, cobblestone streets — with new touches they've yet to experience."
