It's free to get in but every thing else cost.$.26 but you can park on Cannon and walk..
The Zoo lot located between Stockton and Lake Shore Drive is $26. Understood that you didnt ask about ride shares or public transportation but those are viable options as this is a very congested area when the weather is nice.
Not sure but if you're in the city you can take the bus as well. 151 and 156 stop right in front of the entrance.
20-35 depending on how long you stay
Unsure about parking. We used Uber.
Roughly 20 bucks. It varies depending where you park.
