One of the cheapest UNESCO towns in Europe to visit and one of the easiest to do badly: what controls the budget is how many separate church tickets you buy and whether you pay twice for the same 3 km of ground.
Come by train from Prague
Direct services run from Prague to Kutna Hora hlavni nadrazi in about an hour, which makes this a genuine day return if you want it to be. Book online for the cheaper fares rather than at the window.
The main station is not the town
Kutna Hora hlavni nadrazi sits in Sedlec, 3 km from the old town, next to the ossuary. Do Sedlec first, then continue in to Kutna Hora mesto rather than walking the same stretch twice - that ordering alone saves an hour and a fare.
Buy the Sedlec tickets at the info centre
Since 2019 the Sedlec monuments do not sell tickets at the door. Everything goes through the Kutna Hora - Sedlec infocentre at Zamecka 279, and the ticket office closes fifteen minutes before the monuments do, so do not arrive at ten to five.
Stay the night and get the town free
The single best-value thing here costs nothing: the old town empties completely once the Prague coaches leave in the late afternoon, and Sultysova and Palackeho namesti after four are the version of Kutna Hora people write home about.
What a day costs
The Sedlec monuments are 30-90 Kc each for adults and 15-60 Kc for children depending on which one, so the whole Sedlec side comes in around 150 Kc. Add a lunch menu in the old town and a beer and you are near 400 Kc for the day. The out-of-town family attractions are what change the maths: Kacina alone is 180 Kc an adult.
