Cēsis Castle, a captivating historical complex in Latvia, offers both independent and guided exploration of its medieval ruins and the adjacent New Castle, with guided tours highly recommended for deeper insight. While generally open year-round, seasonal variations affect opening hours and accessibility, with summer offering longer access and more activities; be aware that the medieval ruins feature uneven terrain and stairs, posing challenges for those with mobility issues, though parts of the New Castle may be more accessible. Expect an approximate entry cost of €7-€10 for adults, and plan for a typical visit duration of 2 to 3 hours to fully experience both castles, climb the towers for views, and navigate the unique candlelight experience in the medieval section—comfortable footwear is advised for the historic grounds.
