The early fall is one of the best times to visit Prague, when the temperature is mild and fewer crowds fill up big hitters such as Charles Bridge and the 9th-century city- center castle. A stroll around the perfectly preserved Old Town, a UNESCO World Heritage Site, is a must in order to soak up the Czech capital’s old-world grandeur and impressive mix of gothic, baroque and Renaissance architecture. Yet, for an all- encompassing bird’s-eye view of the city’s spire-topped skyline and bridges receding into the distance over the Vltava River, head to Letná Park (pictured). This viewpoint above Letná hill doubles as a beer garden, making it a popular hangout spot for locals and visitors alike.
