Explore Prague Castle and St Vitus Cathedral

Looming over the city, Prague Castle is the largest ancient castle complex in the world, crowned by the soaring Gothic St Vitus Cathedral. Here's the budget tip: the castle grounds and courtyards are free to wander, and you only pay if you want to go inside the main buildings. For many, the free exterior wander plus a peek into the cathedral is plenty. If you do want the full interiors, a combined ticket saves money. Go before 9am or after 4pm to dodge the worst of the crowds. We'll explain which ticket is worth it and what you can enjoy for free.
