How long dose it take to go thur the zoo

4 hours

The bus tour was fantastic. Plan to make a day of it.

With the bus tour 20 minutes

5hr to glance at everything

Same as a previous answer. Depends on how fast you can walk and how much time you spend at each area. We started with the bus tour at 10 and we were done at 4.

All day, if you walk through and look at all the exhibits.

all day! and worth it!

5 hours

I did the whole zoo and took the buss tour twice . It took about 5 hours with a lunch break.

Definitely all day -- even then you won't be able to see everything in full detail
