Colonnade na Reistně is just one of the landmarks located 0.7 mi (1.2 km) from central Valtice, so you might want to stop by for a few pics during your trip.
If museums are on your list of things to see, then you might want to head to Nonseum, located in the heart of Herrnbaumgarten.If you want to see more of the museums in Herrnbaumgarten, Oldtimer Museum isn't far either.
