Adopt A Turtle Nest 2024!

Did you know that Cayo Costa State Park turtle patrol volunteers mark more than 300 nests along the Gulf shores each turtle nesting season? It’s true! The island’s natural shoreline and dune beaches are the perfect sites for the turtles to nest. Because human impact has taken a toll on these gentle sea giants, turtles are struggling to survive. We are doing our part along with experts and volunteers around our state and country to see that nests are protected as much as possible.
Now you can, too! When you donate $25 per nest, you will “adopt” one of our turtle nests! Volunteers routinely monitor Cayo Costa’s shorelines during nesting season and use GPS technology to mark and number each nest. When you “adopt” a nest, you will receive a thank you card in the mail, your name will be listed as a donor, and you will be notified via email of the date it was laid. You will also receive an email letting you know when your nest has hatched. Your “Adopt-A-Nest” funds will assist in providing needed supplies used to protect the nests as well as pay for other resource management needs.
