May I suggest once you get down to Karnak that you take the 2 mile trail spur over to the Barkhausen Cache River Wetlands Center, kind of a neat place to nose around for a while if you're a nature enthusiast.
I’m going to camp near Karnak at Riverview Campground and ride as far as I can towards Eldorado and back, but not the whole way. I’ll definitely check out the Barkhausen Cache River Wetlands Center. What’s there?
