Travel Tips

Circuit Tickets
Choose a ticket circuit that matches your time - full circuits need half a day. Buy at official booths or online; street hawkers sell invalid or overpriced options.
Opening & Changing Guard
Enter near opening to see St. Vitus Cathedral before groups peak. The changing of the guard is free to watch at the gates; arrive a few minutes early for a clear view.
Hill & Tram Access
Trams climb toward the castle; walking up Nerudova is atmospheric but steep. Wear grippy shoes for cobbles, especially when wet.
Golden Lane Crowds
Golden Lane is included on some circuits and gets congested quickly - go early. Photography inside small houses is limited; follow posted rules.
