Knoxville Devilhead Road is 5.4 miles in length. It starts at Berryessa Knoxville Road and ends at a locked gate and fence line marking private property (Waypoint 6). This road is easy, however wet weather can create moderate sections due to deep, slippery mud.

Nice and easy mountain off road day trip. It’s through a bush forest so you have a gorgeous panoramic view of the mountains most of the way. This is a no challenge for any off road vehicle at this time but I can imagine it to be a lot more fun after a rainy day. I will definitely return this winter and have some fun spinning the wheels and slide side to side.

Super fun easy ride. Great way to kill the day. We went the most of the ride without seeing anyone. Super dry making it even easier. I wouldnt do it with my Jetta but my Touareg did it no problem. Some one set up a cool little ovstacle course across from the mud stadium which was worth a try as well

Still open during the COVID-19 stuff. Went there for social distancing, it had good trails but this is one of the easier ones. Great views!
