Fun! I recommend. It's just so hot in the spring/summertime but there's nothing the park can do about that.
I would say plan at least an hour if you want to see the entire park. Make sure you hydrate, bring plenty of water with you. Have your phone ready to take lots of pictures. You will see cute little animals, lizards, birds. I wanted to see a snake but didn't get lucky. Maybe you will!
They sell water in coolers. There's a small store, I had to purchase a hat as the sun was too much. I would say plan better than I did, my hat cost me $37 and it's nothing special. I don't know if I will use it again.
Don't wear perfume or too much make up if you're going in the hot times of the year. Otherwise, have fun! I did.
