Is there trails for offroad vehicles behind the brewery or is it strictly for hiking?

Hiking only

Yeah was general asking for utv/atv

There are trails (roads) through Norris State Park. They are primitive roads that are open to vehicle traffic. Not really an off road park but you do get an opportunity to your around the park in your vehicle. Some of the roads requir a little more ground clearance than you would have in a car but none require 4x4
