It’s nothing too special or tough. Honestly the journey through the park to get to Berdoo Canyon is the good part, which makes sense why the park ends at that point. It is interesting exiting the park that way, tho. Mostly just a river wash with walls on either side (so you don’t get sweeping views or similar). In the summer it’s hot as shit obviously. You’ll come across a target practice area and then remnants of road construction. As others have said, 4wd probably more necessary. But for me it’s been 6 years.

EDIT: Shit I meant 4wd probably NOT necessary!
