The evening begins with dinner and then it's off to explore a few animal buildings after hours, checking in on some of the zoo's residents during their nighttime routines. Travel around with zoo experts as your guide and take home fun facts to share. Wind down at the end of the night with snacks, games and stories as you settle in to sleep next to some of the coolest creatures around. Families can choose to attend just the evening activities or they can stay for the entire program and sleep over at the zoo. Feb. 20-21; March 12-13.
