Two questions, how many buildings are open during winter? And which zoo is better Detroit zoo or Cincinnati zoo?

All buildings are open during the winter and the Cincinnati zoo in my opinion is better than the Detroit zoo as I've been to both multiple times. You can also look it up and see some differences and ratings and rankings from each zoo as Cincinnati zoo is ranked number one zoo worldwide.

Any zoo I like, I'm bias because Cincinnati zoo is 1.4 miles from me

All

All the buildings are open in the winter. Cincinnati Zoo is better

Cincinnati zoo. Almost all the buildings were open except for the birds due to bird flu at the moment.

Cincinnati, duh

There is a lot to see in the winter, go during the Festival of Lights. Cincinnati is better, I do believe it was just rated top in the nation by AZA

Mostly open. Cincinnati for sure!

They Always working on something to make it a better place. Never been to the Detroit zoo so I can't compare them. You won't be disappointed.

Most of the buildings are open and Cincinnati is number one for a reason... 😉

Have not been there in the winter nor have I been to the Detroit zoo. I would call them and ask them.

Don't know about the buildings but Detroit zoo is better
