A fin-whale skeleton greets you at Budapest's Natural History Museum, which houses a raft of interactive displays over three floors. Interesting exhibits focus on the biodiversity of coral reefs and the natural resources of the Carpathian Basin. Noah's Ark, part of the new Variety of Life exhibit on the 3rd floor, and the outdoor dinosaur garden are particularly fun. It also hosts a range of temporary exhibitions, and admission is free for under-26s on the first Sunday of the month.
