Brown Mountain a huge attraction to ATVs and Bikes, there are Ton of them there, Al through I haven't ridin on a Bike there I have heard the trails are really good.
Tread Lightly
Off-highway-vehicle trails are
designed to minimize impact on the
environment. National forest laws are
enacted and enforced to protect the forest
from damage to the land, water and
wildlife.
Please follow these rules:
● Stay on designated routes marked
with symbols that show the type
of vehicle you have. Shortcuts are
not allowed.
● Stay off trails that are closed for
restoration. Avoid wet trails and
wheel spins.
● Spark arresters, mufflers and
brakes are required for motorized
vehicles. Be sure your spark
arrester works properly. Remember:
you are responsible for any
fire you start.
● Keep noise levels low. Many
people go to the forest to get away
from noise.
● Don’t harass wildlife.
● Carry a litter bag and pack out all
trash. Learn and use no-trace
camping techniques.
● Remember to use the restrooms at
the trailhead before hitting the
trails. In the backcountry, bury
human waste and toilet paper
about six inches deep and 200 feet
from water.
● Ride straight: no alcohol or
drugs are allowed on the trails.
