A tad pricey but it was really one of the best zoo's I've been too. My hubby had to work in Rotterdam so he sent me and our two girls off to find the zoo. We started off with the sealife area, had CA sea lions up first lol being from CA which we've seen but they were really active, swimming and barking. Their aquarium is really beautiful with so many window displays including a large glass tunnel that had the most amazing views of the sharks, stingrays and fish swimming over your head. The kids were so excited to be surrounded like you were underwater swimming with them. We saw so much and everything was so in your face it was amazing. The kids loved seeing the tiger exhibit they came up right up to the window *although there were some middle school kids there on a fieldtrip or something and they were being super annoying banging and yelling at the windows. I wish there was some park employee there to tell them to knock that sht off! In fact, come to thing of it I don't recall seeing any caretakers or park employees in any of the outdoor exhibits. But moving on, my personal favorite and you must see is the Amazon exhibit. You walk into this and bamm the heat hits your face. You are in a jungle of flowers, plants/trees and there are butterflies small and LARGE flying in your face. I had to hold my shreeks and my hands down as my initial inclination was to scream and swat something that is flying in my face. LOL! The butterflies would stop and feed from these large flower feeders, it was really beautiful to see them so close while the fed. I highly recommend you visit this zoo if you're in Rotterdam. It took us 4 hours to go through the zoo and really enjoy it and maybe because we went during the off season and middle of the week but it wasn't crowded at all which made it more enjoyable. They have a cafe, gift shop and snack shops through out. read more
