said it is a decent goat trail.
95 is decent road but it has been several years since I have been on it. Used to run from Boise up to Lewiston and beyond. You will have some climbing and curves. Long 6% pull going north near White Bird about 6+ miles long. Down grade is nothing drastic.
12 is worth the drive but don't be in a hurry. You have to drive it as it is curvy and follows the river. Lolo Pass on the ID/MT boarder is another steep climb but not impossible. (FWIW there was some million pound plus loads hauled over it several years ago) Road is decent shape and lots of pull outs to take a break.
We stayed for a night at Square Dance Center and Campground near Lolo, MT. Nice Mom and Pop place. Easy access to the river, staff was great.
Never been on 13 between Grangeville-Kooskia.
