Thet were why we went to Beppu for a day. We might recommend staying in Oita and just traveling to Beppu to see them. The zoo elements were all poor. They seemed poorly maintained and we felt sorry for the animals. They "bottom two" were better maintained. Don't forget to use you bus pass to get a 200 yen discount on the 8 hells ticket booklet. Taking the bus up takes some time, but it's very affordable.
