I'm doing one star because... I used to live in Eureka and work at the zoo 20yrs ago. I moved to GA but came to visit my mom who still lives in Eureka. I came to the zoo and they asked for my zip ( I was thinking for visitor information) then was asked to pay $50 for 2 people. They charge more if you don't live here. I told the lady my mom lives here, I used to live here and work at the zoo... she just laughed and waited for the money. Wow! I would have said eureka zip 95501 had I known. So heads up... say 95501!

Update: after walking around only about about 50% of animals we're out. Barn closed, which we wanted to see most. They don't tell.you when you enter that parts of the zoo are closed yet charge full price. We saw them letting people in at 5:00 full price unknowing they woudnt see much. The bathrooms were aweful dirty and no supplies. Disappointment. It was a better zoo when it was free. You saw more animals and keeper interaction.
