Barry has given the point to point distance that the horsemen used. The wagons used the pass itself. To get to the pass you would firstly travel around two miles across the open plain, cross two streams and turn up to the mountain, around another mile. so before becoming 'invisible, to the mission station around 2 to 3 hours. Once on the approach and you start to climb then waqgons would be double teamed and spend a day getting to Vermaaks. On the mountain top its pretty flat, ish to Helpmakaar so around another two hours or so. So total time I would estimate at around 21 to 22 hours. The alternate route would be an hour to 90 minutes for a mounted man and 2 1/2 to 3 on foot.
