This annual family event returns for the 15th year with thousands of bright lights, sparkling ornaments and trees, lighted animal figures, and displays transforming the zoo sanctuary with holiday spirit. Local caroling groups and musicians provide the merry sounds of the season, and the Folsom Valley Railway miniature train provides special nighttime rides. 

Wild Nights and Holiday Lights is open from 5 to 8:30 p.m. December 5–7, 11–14, and 18–22 (weather permitting; heavy rains will cancel). All proceeds from the event benefit the zoo sanctuary animals.

Event admission is $12.99/person for the first hour and $11.99/person for the last two hours. Train tickets are $7/person. Children under the age of 2 are free.

Tickets are limited and must be purchased in advance on Eventhub.
