Unless things have changed since last year...you would go to the tax collectors office on Hwy 331 and present the following items: Proof of property ownership in Walton County, Proof of a registered, insured 4 Wheel Drive Vehicle and the money for the permit. It used to be $105 per year (i think)..but I am not sure now. Also the permits expire June 1st of each year...so if you get one now..you will have to get another one by June 1st. Don't hold me to every bit of this...but this is what was required last year when i renewed mine.
