This is a unique evening tour that only operates on the days when the Hermitage is open later (until 9:00PM). There are typically no crowds during this time, which allows guests to see rooms and art that tourists typically don't get a chance to see during the day tour.
This tour is at a much more relaxed pace than guests typically get to experience, allowing for more opportunities to ask questions and enjoy what the Hermitage Museum and Winter Palace have to offer.
