This was my second time at Zoo Lights and they have had different things both times which was nice. They seem to add more things each year. I went with a group of 4 adults and we had a blast. Really gets you in the Christmas mood ! (:
Price is $20 for adults and takes about an hour but can be longer if you sit to enjoy the Lights or make stops which there is many areas to do so. They have a polar slide, camel rides,lots of vendors for hot chocolate/popcorn and Lego animals. Keep in mind there is usually not real animals out but the Lights are shaped like animals and it's smells like a zoo you still get the feel of the zoo. They lights are really pretty and romantic. My favorite part is the light show over the water that blinks to the sound of the music. It's nice you sit on the benches and enjoy the show.
It can get busy so nice to go early but I highly recommend. I think it's one of the better light shows in Arizona for a decent price. It's cold so bring jacket and gloves if you have some. Nice to walk around with a nice hot cup of hot chocolate too.
