Vidam Park in Budapest

There is one, called Vidam Park, it's pretty nice, expect dodgems, a fine merry-go-round and the oldest wooden big-dipper in Europe, at leats that's what they claim. This park is located just behind the zoo and is great fun for kids. The whole area is geared towards fun: besides the amusement park, you will also find two museums, a huge green space, thermal baths, the circus, and much more. It's a busy and fun place to spend a few hours, or the whole day, but it's definitely a place to go with kids, it won't be that much fun without them.
