There is approximately 1¾ hours of walking on this tour, some of which is over cobblestones. The boat route is subject to change depending on the water level and weather conditions. There are 14 steps at the embarkation/disembarkation of the canal boat. It may also be necessary to cross other boats to reach your specific vessel. Whilst there are sufficient seats for everyone on the boat, we cannot guarantee that you’ll be able to sit in the area of your choice (either inside or on the open deck). There are 31 steep steps to access the fortress jail. The Church on the Spilled Blood is currently undergoing restoration; some of the domes are surrounded by scaffolding. The order of this itinerary may vary.
