Things to do in Moscow – Aquarium Hi friends! If you don’t know where to go in Moscow and you want to turn out in magical underwater world, welcome to Moscow aquarium! I think this is the best place in Moscow! I have never been in big aquariums in my life and I really enjoyed and was impressed! This is the biggest aquarium in Europe and there is a huge space inside and very beautiful decorations. It is on VDNHa subway station. Enjoy!
