off roading in tennesseeThe adventure of a lifetime for most would be the opportunity to visit a historic abandoned train tunnel and either walk or drive through one. You might ask “How Can This Happen”? The abandoned Nemo train tunnels are just 6 miles SW of Wartburg, Tennessee. Nemo is situated in the East Tennessee Mountains, just north of the Catoosa Wildlife Management Area. This area is full of many different attractions, but it’s rare to come across train tunnels like these. There are actually two abandoned tunnels, which are both accessible to the general public to explore. When you’re looking for new adventures these tunnels are great for Easy Off Roading in East Tennessee and are a total step back in time.

Walk-Thru or Drive-Thru Tunnels

Note: The tunnels are old and from age can be hazardous. At the time this article was written the tunnel seemed stable. If conditions change let us know. WARNING! You will be driving next to active Train Tracks. Stay away from the tracks. Trains come without warning every 15 to 20 minutes.

Just outside The Catoosa Wildlife Management Area are two one-of-a-kind tunnels, both of which you can travel through at your leisure. In fact, you can easily explore one of these tunnels on foot. The tunnel isn’t dangerous, but it is cold, dark and gives off an eerie feeling upon entrance. In fact, it’s the suspense and anticipation of what you might see that makes it exciting. A short 5-10 minute walk will take you from one end of the tunnel to the other and a flashlight will definitely be needed.

If you would prefer to drive instead, there is another tunnel suitable for any stock off road vehicle. Tunnel #24 makes off roading in Tennessee a blast! It will be a naturally dark ride, however, so you’ll want to equip your vehicle with a suitable amount of lights so you can see where you’re going. This will be handy in case of hazards, such as standing water which may collect up to mid-tire within the tunnel’s depths. Tunnel #24 is also the longest tunnel to explore in the area. Eventually, you’ll find yourself traveling in pitch darkness so dense there will be no visible light ahead of or behind you. We guarantee a trip through Tunnel #24 will top as the crowning moment of your trip! If you’d like to experience what the tunnel is really like before your trip, you can find videos online from other people’s tours.

Explore Trails Outside the Tunnels

These abandoned train tunnels are just east of the Rock Creek Campgrounds and Catoosa Wildlife Management Area on the east bank of the Emory River, so there is plenty to see around them as well. Natural trails are available for hiking, biking and even kayaking and fishing on the Emory and Obed Rivers. Once you get through to the other side of a tunnel, you’re naturally transitioned into a trail where you can continue exploring. Your adventure doesn’t stop at the end of the tunnel! Visit The Catoosa Wildlife Management Area which features numerous other dirt roads to travel and hiking trails – too many, in fact, to explore within one day, or even one trip! You will want to make sure you have a cooler full of drinks and food so you can spend the whole day enjoying nature.

Important: Landowners May Close Access

Readers Comment: “The tunnel is not in the management area, the road to the tunnel is on private property and the tunnel is part of the rail road easement. This is an important point to make: All visitors on the south end access road, to the tunnels, needs to respect the land owners property. The landowners allow the access road to stay open to get to the tunnel. Only drive on the access road and do not do any off roading on the access road or along the easement! Some people are tearing up the landowners property and they May Close Access.”

Historic Nemo Train Bridge

The historic Nemo Train Bridge is a must see while you are there. This bridge is part of the Cumberland Trail system. The Tennessee Department of Environment and Conservation’s Cumberland Trail System is in the process of saving this wonderful bridge. To read more about the Nemo Bridge CLICK HERE.

Wildlife Management Area Regulations

The Nemo Tunnels are located just north of the Catoosa Wildlife Management Area.

It is important to review Tennessee Wildlife Management Area’s  General Regulations for specific restrictions to make your trip worry free.

Motorized Vehicles Requirements:

Plenty to See and Come Back for More

Whether you have children or just want to get a group of friends together to explore these abandoned tunnels, you’re sure to have a great time. Some of the trails follow the Obed River, which has plenty to see and explore as well. Once you make a stop at Catoosa Wildlife Management Area, you’ll want to come back to do some more exploring in Morgan County, Tennessee pretty soon. There’s so much to do in this area that we could not cover all of the information about Morgan County. For more information on Morgan County TN CLICK HERE.

If you’re a history buff, a railroad fan or just a seeker of the unusual, there may not be a better experience than the abandoned Nemo train tunnels in Catoosa Wildlife Management Area. Be sure to subscribe to our blog for more adventures like these.

  2. Ⅿy brоther recommended I might ⅼikе tһis website.
    He was totally right. This post actually made
    my day. Yoᥙ cann’t imagine simply how much time I had spent fߋr this info!

  3. The tunnel is not on the management area, the road to the tunnel is on private property and the tunnel is part of the rail road easement up to 2026. This is a important point to make is that on the south end of the tunnel all visitors need to respect the land owners that allow the road to stay open to get to the tunnel. All the off roading that is done along the easement road is tearing up the landowners property.

      I added an “Important” message to the article.


  4. Did visit, and was perfect intro ride 4×4 with the wife. Other than the fact we ran into another vehicle coming in from other side and I had to back out what was 1/2 the tunnel and definitely the roughest portion, was good. Walked the other tunnel. Drove down to the trails by the water and rode just a bit, as solo and no winch, did not get into the mud bog holes. Will revisit another time when I am back at Windrock with it being to close. Thanks for posting about this place!

  5. We done Nemo this weekend. Had an absolute blast. Very easy to navigate. Theres also a picnic area across from the entrance of the trail head. Makes it very easy for unloading 4x4s if they need be. Also has permanent porta pottys, several picnic benches, hiking trails and of course Nemo Bridge. Was a great place to visit. Will definitely be coming back.

    • I have never tried it in 2WD.
      So if you do try it take a friend that has 4WD and a winch just in case you need help.
      It is recommended that when off roading never go alone. Always have a second vehicle.

      Now for your answer:

      You should not have an issue driving through the Drive Through tunnel in 2WD and to the walk through Tunnel.
      (Making sure you stay clear of the active tracks!!!!)

      When leaving the area you may have trouble driving the bypass in 2WD.
      Be careful of vehicles entering the area if you have to drive back through the tunnel to exit the area.
      If you exit through the Drive through tunnel make sure you have GOOD BACKUP Lighting in case you encounter another vehicle and have to back out of the tunnel!

      Let me know what you do and how it was.

      PS: Make sure you read the notes on the Map!

  6. Has anyone noticed on the south entrance, I think, there are private property signs? I just drove up there to find it before I take the Jeep. I was going to go in the morning but don’t want to get in trouble or go somewhere I’m not suppose to.

    • We have not heard of any changes.
      The Private Property signs should be for the private property either side of the Southern Access Road to the Tunnels.
      Stay on the Access Road and you should be fine.

      Make sure you read all the Notes for the waypoints on the Map!!!


    • Thank You for your comment.
      Let me know when you are thinking about going and I will see if any of my friends in Murfreesboro TN want to go also.
      My wife has been wanting to go again and also want to visit tour Brushy Mountain State Penitentiary.


  7. Can the trail support a full size 4wd? We have a 4wd diesel Excursion “stock but heavy, wide and tall” not sure if it would be advisable to drive back or hike in.

    We do have capable 4wd IH Scouts but will be traveling from out of state and won’t have it with us
