Is there are a lot of visitors during weekends? Is social distancing possible?

I agree with Nicole! The zoo is very popular, which means a lot of visitors. By excersizing caution, self social distancing can be achieved.

Yes a lot of visitors, but if you are willing to hang back and let groups past you social distance is still possible. I suggest skipping things like feeding giraffe or going on rides that will mean waiting in a line. We also didn't do food there due to lines and crowds in those areas. It can be done safely with caution
