The Houston Zoo is changing its free day schedule. Starting this month, the Houston Zoo is changing when it offers free admission to guests. Instead of five designated holidays, the zoo is now free the first Tuesday of every month after 2pm.

The zoo moved the free days to try to tame the usual big holiday crowds and free up parking spaces.
