Who, where and when?

Some royalty, no idea when. Where....Looks like Goldengate or just to the southeast perhaps, Mount Qwaqwa?

Is that Jan Smuts on the right? I would guess Royal Natal?

March '47.
RNNP (hence the Royal).
From left to right:
QE2 far left (then Princess Elizabeth age 20)
George VI next to QE2
Queen Mother (Elizabeth Angela Marguerite Bowes-Lyon)
Princess Margaret (Elizabeths Late sis) second from right
Jan Smuts (far right)

Is the girl next to Jan Smuts not Queen Elizabeth? In the Natal National Park, which became Royal Natal National Park after her visit?

was busy typing just as mnt_tiska posted the answer.

Yes, I think Plouw is right:

RNNP (hence the Royal).
From left to right:
Princess Margaret (Elizabeth's Late sis)
George VI
Queen Elizabth, Queen Mother (Elizabeth Angela Marguerite Bowes-Lyon)
QE2 (then Princess Elizabeth age 20) second from right
Jan Smuts (far right) (note standing a little distance away)

I don't think any of them made it down the mud-slide or up the chain-ladder.

Well done guys (and google) Got a bit nostalgic last night when i saw a tv show on the queen, a bit was on her visit to sa. So i thought i would see of there was any footage of the RNNAP and there was on a BBC site. Such a long time ago. The following year, 1948, SA started down the road of apartheid. Imagine if it had been different!

On the picture, is that Dooley in the background, with the forest in the centre that contains Tiger falls?
