Panorama Route, Mpumulanga - how much can you actually ride?

[Imtb]

If I wanted to take 6 days and explore from Graskop, Pilgrims Rest, Gods Window, Bourkes Luck, Mac Mac, Lisbon Falls, Blyde River Canyon etc...and maybe further north to Haenertsburg or Misty Mountain, how many of these can one actually ride to? Tar? Gravel? If one had vehicle transfers and included some riding each day (30km - 60km) - where would the best riding/routes be, not in terms of trails and single track, but more in terms of scenery and exploring the most scenic and interesting parts by bike, preferably on gravel roads and jeep track - or quiet tar roads I guess. Any locals? Thanks
