Wawel Royal Castle-State Art Collection is a must-visit historical complex in Kraków, offering a rich journey through Polish history. While the castle grounds are freely accessible, entry to various exhibitions like the Royal Apartments, State Rooms, Crown Treasury, and Armory requires separate or combined tickets, typically ranging from 20-35 PLN per exhibition (check current schedules for specific pricing and potential free admission days), and booking online in advance is highly recommended for timed entries during peak season. Visitors can choose between self-guided exploration, often enhanced with audio guides, or opt for guided tours for deeper insights. The complex is open year-round, though opening hours vary seasonally, and accessibility is generally good, though some historical areas, like the Dragon's Den or parts of the Wawel Cathedral, involve stairs. A typical visit can span 2-3 hours for key exhibitions, extending to a full day if exploring all areas including the Cathedral and Dragon's Den; comfortable shoes are advisable due to the hill-top location and extensive walking.
