Trail Information

Highlights

If you want crazy hard and people say you are a bit insane, then Jack Hammer is the trail for you. Known throughout the off-road industry as one of the single hardest off-road trails in the world, Jack Hammer will not leave you disappointed about being challenged. Many have tried, and many have failed even in the most built rigs. This 4x4 trail is going to bend, break, and destroy the common failure items and things you didn't even know that could get damaged. Have your pocketbook ready and a solid recovery plan because it is rare people leave this trail untouched. This trail is only for the most experienced with a very built rig and strong roll cage. The rating of this trail is well past difficult and is above severe in the extreme area. Do not attempt this trail alone and do not attempt this trail unless you have recovery gear, spare parts, and a group of other offroad extremists that are looking for a day of fun in Johnson Valley, California.
