The honest question is not whether a trail is hard, it is whether it is harder than your build and your recovery gear. Enter slope, surface and water depth for a 1 to 5 rating and what it expects you to carry.
Off-Road Trail Difficulty Estimator — Can Your Rig Handle It?
A trail rated 7 on the Sunferno scale needs specific approach angles, suspension travel, and tyre size. Know if your build is ready.
Enter your vehicle’s ground clearance, approach angle, tyre size, and drivetrain. The estimator returns the maximum trail difficulty your build can handle.
Attempting a trail beyond your vehicle’s capability puts you, your passengers, and recovery teams at risk. Knowing your capability lets you plan appropriate routes.
