How far in advance can you make reservations

I believe if you're a Florida resident, you can make a reservation as early as 1 month in advance. I'd call to confirm.

Trimble Park is best in the cooler months like Jan-March. Reserve 4 months out. Summer is too hot and too many bugs.

4 months for all the best dates (Nov-Apr)

I think it's up to 11 months in Florida State parks. But Trimble Park is a county park. So not sure

Many state parks cap at 3 months that I have encountered.
