The boat route is subject to change depending on the water level and weather conditions. There are 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 many steps in the Palace and narrow steep steps into the cellar. Comfortable, non-slip shoes are recommended. Special overshoes have to be worn in Yusupov Palace during wet weather conditions to protect the floors. These will be available on entering the Palace. Crowds are to be expected and you may have to queue outside in all weathers. The Church on the Spilled Blood is currently undergoing restoration; some of the domes are surrounded by scaffolding. The order of visits may vary.
