Omaha's Henry Doorly Zoo will always be my favorite spot to go no matter how far away I move. It's the 2nd largest zoo in the world if I remember right. It has taken in millions of visitors from over the world and is a huge torist spot. It houses more then 17, 000 animals and at least 48 being endangered species.
It has the largest cat complex in North America, the largest nocturnal exhibit and indoor swamp. The largest indoor rain forest and the largest indoor desert! The desert dome is also the largest geodesic dome in the world! The aquarium is the 2nd largest in the world as well and houses everything from sharks to alligators.
Some of my favorites are the penguins because you can actually watch them dive into the water and swim. It's also funny to watch them interact with the people cleaning their home. The cat complex is another favorite of mine it has leopards, lions, bengal tigers, white tigers, and funny to watch them run around and play. They recently put in a new Gorilla house which is amazingly huge. They have a new Orangutan island also that I haven't been to yet.
There are outdoor monkeys and sea lions. Also prarie dogs and they are so cute! They have a few educational places as well where you can go in and milk a cow statue. Also a skeleton riding a bike who explains out muscles and how you use them. They also have a huge Imax theater that I alos have never gotten the chance to go enjoy.
At the Information center there is a stand where it shows you how bats hear sounds in waves and it gets their attention. There are many snakes, lizards and turtles there too. There is an outdoor bird aviary which is also one of the largest. They have flamingos! Another of my favorites is the Koi ponds, you can put in a quarter, get fish food and feed all the Koi. I have always wanted Koi ponds but that's the closest I'll be for a while.
This is my all time favorite zoo and I would suggest if anyone is passing through Omaha Nebraska that you check it out. Admission is a little over 11 dollars which it has gone up since a few years ago and they now changed the free admission from 2-4 years old instead of 5. It's still all fun though and I suggest you take your camera. It's open year around.
