I am planning on visiting the zoo in July. I have already purchased a San Diego City Pass and was planning on using this for admission. Will I still be able to do this with having to make reservations?

Double check the city pass website too in addition to calling the zoo

I would think that you could but I would call the zoo to make sure

Check the website

I tried calling but was on hold for 40 minutes. Will try again.

I would call to make sure.
