Closest to you would be a drive to Clarens for a weekend taster plenty of hikes and scenic drives.
Drakensberg via Clarens down to Winterton always more scenic off the freeways, slow as roads never in great condition!
An interesting read on route I would select https://www.nomad-as.com/2015/09/drakensberg-royal-natal-np-freestate.html
!BEER Sundowner time again 🙃
Beautiful read worth bookmarking, I wish I could hit the road already! 😃
I've got to put together a few thousand Rands for that.
