If you want insanely hard, then the Hammer Trails are for you. Sledge Hammer is the southernmost trail of the Hammers in Johnson Valley, California. This extreme 4x4 trail is a collection of large boulders, massive ledges, towering waterfalls, vertical climbs, and spots you just have to drag through. This trail is going to make you work for it if you are wanting to complete it. Once on this trail, it is clear why this is one of the hardest trails in the country and why it makes the cut for one of the hardest parts of the King Of The Hammers race. If you think you have what it takes to do this run, have a rig that is built for the extreme, and have plenty of off-roading experience, then this is for you!

Trail Difficulty and Assessment

Trail Navigation

Like Jack Hammer, the trail consists of waterfalls, massive rocks, and areas where you have to set up for following obstacles. This trail is for the adrenaline junkies and the people that want to do the extreme. Sledge Hammer will likely leave its mark on even the most built rigs with the most experienced drivers. Planning, spotting, and patience will be required to complete the trail. For a trail like this, it is never-ending major obstacles that are just feet away from each other. There are no breaks or rest spots on this trail. Once you are in the rocks, it is like that to the mailbox at the top. This guide covers what we feel are some of the most important obstacles to plan for, but note, even the obstacles on this trail that might not be as hard could easily roll a vehicle over or break someone. Planning is important, and spotting is critical. This trail is only for the highly experienced to extreme drivers with a well-built rig and strong roll cages. Do not attempt this trail alone, and do not attempt this trail unless you have recovery gear, spare parts, and a group of at least 3 vehicles.

Another great day on a fun trail. The trail changes every time and the plaque run has changed quiet a bit. But that is what makes it fun

So the plaque run has changed and will likely result in a lower of the rating on this trail. There is now a right line that is much easier then before. The plaque line was the hardest part of the this trail meaning the rating will likely drop. I will see about getting out there to take a look, but right now I would say it is dropping down to an 8 or maybe 7

Difficulty Accuracy: Harder

After the koh guys preran the last few weeks, after plaque rock is incredibly hard now. 3 4 foot tall rocks sitting in the middle of the line. Unless you have a flat bottom to cradle the rocks you have to ride the wall to get through. Great trail.
