Upington FlyFishing

Hi all

I’m on a years contract in Upington so put all the saltwater kit in storage and recently bought a xplorer 5wt set up and read some articles on flyfishing for yellows. My only issue currently is access to nice rapids and pools that one can access on foot rather than via boat.
Has anyone fished the area and know any accessible spots/ kind farmers willing to let one fish on their property?

Thanks in advance!
