Before entering the Catherine Palace, you will need to put on a shoe cover over your shoe to protect against damage to the wooden flooring. Do be very careful as the floor is very slippery. An elderly member of my tour group slipped and fell as she stepped into the Grand Ballroom. Walk slowly and with carefully - keep your feet close to the floor by gliding across the room.
After Amber room was reopened in 2003 the number of visitors increased dramatically. The Personnel of the museum do not know what to do with visitors. There is no any organised que before entry and guides with the help of their tour groups take gates by a storm!!!
Here is a control post in the museum. Metal detectors are not working and used just to stop the crowd ;-(((
It seems funny now (from a distance!), but there was a pack of wild dogs on the palace grounds during our visit. Security kept coming out and scaring them away, but they would return and aggressively threaten anyone near the building.
Luckily for us, they stayed near the entrance. . .they never came out into the grounds (maybe they were waiting for food?).
You shouldn't let a bit of rain stop you from coming to visit either Pushkin or Pavlovsk ~ the grounds are beautiful for walking and you'll be ensured of some quiet time here. However, be sure to bring an umbrella and sturdy shoes. . .the pathways are all dirt and get washed out very quickly. . .
