Old Town Square in Prague is an easily accessible, expansive public space, mostly flat and paved, making it welcoming for all visitors. It's fantastic for both solo exploration, allowing visitors to absorb the historic atmosphere, and guided tours which offer deep historical context for its iconic landmarks like the Astronomical Clock and Týn Church. While enjoyable year-round, with vibrant markets in winter and lively street performances in warmer months, there are no strict seasonal restrictions, though some attraction hours may vary. Entry to the square itself is free, with costs arising from visiting specific attractions (e.g., Old Town Hall Tower), dining, or souvenirs; expect a moderate budget if exploring specific paid sites or eating on the square. A typical visit to soak in the ambiance and see the Astronomical Clock show usually lasts 1-3 hours, but one could easily spend longer. Don't miss the hourly Astronomical Clock show, and be mindful of crowds and pickpockets during peak times.
