Zoo lights are tonight. Then starting this coming Friday night thru Dec 23 everyday during that time zoo lights from 5 to 8pm. Day after Christmas then we will do it again for the week same time until I believe the 29 or 30th of Dec.
There is a few weekdays as well but I suggest checking the Chaffee Zoo website. I just purchased my ticket for November 26th, opening night.
Every Friday, Saturday, Sunday starting November 26 until December 30
