On their website the Dallas Zoo explains that Dollar Day is their way to thank the community that they say supports them year-round. The event happens every year and makes the zoo affordable for the entire family — with the cost of admission only $1 per guest.

But with the chance for another day of record-breaking temperatures, it’s recommended you arrive early to beat the heat and the big crowds.

There are some ways to stay cool while at the zoo… hanging out with the penguins in the air-conditioning is one. There will also be spray fans, water bottle refill stations and extra water misting stations around the park to keep guests cool and hydrated.

There will be plenty of shade as visitors walk around the exhibits. There are also a number of snack deals inside the park, including $2 hot dogs, chips, and sodas, and $1 canned water.
