You will get in if you show up any time. Never seen it full. If I were you I would go on the FWC site and apply for the first 9 day permit. They get returned all the time and you will get one if you apply. Just be ready for a shock. Green Swamp is one of the hardest places to hunt. Think of the hardest places to hunt in Wisconsin and it's tougher. Some really nice Florida bucks there. You'll find sign but they are smart deer.
