You have to purchase the permits at the Wilder city building, during work hours. They do have a parking and a launching permit, I used to put my canoe in there so I just bought the parking permit, I can't remember how much it was (I think $20.00 for the year), but it's $50.00 a year for the launch permit. You can probably put your yak in at the park in Newport, Gen. Taylor Park. Also there is a free ramp on up the licking a bit, it's off Decorsey Pike in Kenton Co.
Good Luck
