Visited the Oklahoma Zoo twice, on the 15th November and the 22nd November 2022. As family member, I only paid $4.50 (full senior price was $9.00). It was half price for Military Family for the month of November, in conjunction with Veterans' Day (11th November 2022). Admission for Michael, as a Veteran, was free.
The colorful decorations were lighted up by the Zoo Safari Lights (presented by OGE, Oklahoma Gas & Electric Company), from 5:30 - 11 pm, from 12 November 2022 to 1 January 2023. We didn't visit at night but I can imagine the beauty of the lightings and the Zoo.
