The National Park plays only a small part in the series. One of its only appearances is in Gone, when it is visited by Sam, Astrid, Quinn, Edilio and Little Pete when they are running away from Caine.
The Park is mentioned again in Hunger, when Orsay tells the group that she saw them in the forest there and looked into their dreams. She also reveals that she lived in the Park for a while with her father, and that was where she had first learned of her powers.
In Fear, Astrid is living near the FAYZ barrier in the park. She has set up tents and a campsite, and mostly lives off the land.
Its final appearance is in Light, when Gaia escapes into the park from the Lake Tramonto Massacre, after being seriously injured by Brianna. To provide a distraction, Gaia uses Sam's light to set fire to the forest, dried from a year without rain, which spreads all the way down to Perdido Beach.
