All of the land in Suffolk County is owned by someone, whether it be private, town,county, or state you do need permission we all know that. There are county parklands that are good hunting but you need to be a resident of suffolk and check in with the park. I' ve hunted brookhaven town property in the the past and never really had a problem but one time got kicked out by one of the town enforcers. All the state land cant be hunted there are designated areas and you need to check in. There is town property in Southampton but you cannot hunt on town property in southhampton they will ticket you.Hope this helps and if anyone else can chime in if Im wrong.Good luck
