I've heard very good things about the Omaha Zoo but after going myself, I don't have very good things to say about it. Good things? Yes. Best zoo ever? No. It was very hilly and everything was really spread out. Read - we didn't use a stroller and had a toddler there during nap time. I guess that probably wasn't the Zoo's fault now was it. Oops.
The best part of the whole Zoo was the aquarium (however if you read online the Henry Doorly Zoo is listed at #8 in the nation and is best known for its 1.5 acre Lied Jungle...apparently we missed that) which was packed. Completely packed standing shoulder-to-shoulder with the person next to you. It was dark and hot so pretty much just set everyone up to be claustrophobic even if you've never been claustrophobic before. Tylee didn't mind.
The rest of the zoo was just okay. We missed the Elephants and Zebras but tried to catch most of the big stuff. We saw more animals than shown here but the zoo was literally SO crowded that it was hard to get a picture without someone (other than Tylee) in the snap.
Overall, we had a good time and it was the perfect distraction in the middle of our long car ride. Tylee fell asleep within minutes of being in the car and we headed north to South Dakota.
