Sounds like an interesting adventure, but first consider a few points
- Check your geography and the relevant ICAO maps
- To visit the garden Route, the town of George is a more suitable base
- Cape Town is obviously best for seeing the Cape Peninsula and flatlands
- There is a solid line of mountains to the North and East of Cape Town that could offer problems if you have only flown in the UK flatlands
- Cape Town to Joeys is about 1200 km and is a lot of nothingness, you get jaundice looking at the maps of the Karoo and the Free State
- Paperwork is best sorted out in the UK, there appears to be some gent at Popham who can help, the basic requirement is to write air law (SA CAA) and take a check ride
- You can hire and fly at Cape Town International and George, and possibly Fisantekraal (North of CT), rates about ZAR600 dual on PA28
- No jabs required
- Most important point, the summer starts in the Cape on 25 December, it's a fact
Hope this helps
