Zoolights has only gotten BETTER every year! We've been members for years and still enjoy going every year to see the lovely lights, displays, and hearing the music. The zoo has no control of how many people show up on any given night, nor if couples make out during their visit, so these factors shouldn't even be considered in a review as some have noted!
As a wonderfully run not-for-profit zoo, they do a fantastic job at putting this on each year, as it takes MONTHS of preparation to get the displays ready for season. We noticed several new animal lights this year (namely tigers) and love that they keep improving. Keep it up, Phoenix Zoo!!
