3 must-see hop-off attractionsWhen you come to Riga, you simply can’t miss the chance to explore the Old Town, so make sure that’s on your list of stops to hop off at. It’s a delightful area that’s full of charming cobblestone streets and architectural treasures, which is why it’s a UNESCO World Heritage Site. While there, head for incredibly narrow Rozena Street and see if your arms are long enough to touch both walls at once. Another place you have to hop off at is the Academy of Sciences, an imposing communist-era building, which was the first skyscraper built in Latvia. Climb to the 17th-floor for unbeatable views over this hidden gem of a city. Finally, make sure you hop off to visit the Powder Tower, which was originally built as part of the city’s (very much needed) defensive system. It takes its name from the fact that gunpowder was stored there in the 17th century. Today, it is home to the city’s excellent War Museum, which tells the story of the country’s political and military history.
