I don't think 270 is what I would be looking for. lol
If I were coming up from Texas, I would route over to Talihina OK and then onto route 1. Stay on route 1(Talihina scenic Pky.) This will take you to 88 and into Mena AR. If you have never done this ride, You will enjoy it a lot.
Stop at the lodge.
Ok now up AR 23 to AR 16 to Ar 7 to Russelville. Stay on 7 to Hot Springs AR.
That is a super loop. 23 in my opinion is as good as the Dragon. It's called the Pig Trail.
16 is a great road as well as 7 down to Russelville.
I could ride those roads every day.
Look at the time on that and let me know if that fits or not.
The mountain roads always take longer to ride...
