What's the best off-road testing spot for Nissan Patrols?

I'm planning a trip with my buddies and we want to push our Nissan Patrols to their limit. Any recommendations for an off-road testing spot with varying terrain and difficulty levels? We're all experienced off-roaders and looking for a challenge.

One of the best off-road testing spots I've been to is Johnson Valley in California. It offers a mix of sand dunes, rocky terrain, and mountain trails.

For a more rugged and extreme experience, I suggest checking out Moab in Utah. The trails are challenging but definitely worth it for the amazing views.

If you're on the East Coast, I recommend the Hatfield-McCoy Trails in West Virginia. There are over 700 miles of trails to explore with varying difficulty levels.
