The drive up can take a few hours depending on how bad the road is, as there is a tendency for it to be washed away(like which happened with us). It also gets really cold when you reach the top like really cold. Once you reach the top you're greeted with a sign like the following.
Then you have to go to customs, at least you should since I don't think they actually check nor care with you smuggle in anything. You just walk in they stamp you walk out, that's it. And to the left of customs there is a small establishment, or should I say the highest pub in Africa. Just a note a double the pub is by far not very cheap, if I remember correctly I paid R80 for a double whiskey, I was told this is due to them having to import all the alcohol from South-Africa and because of this the only beer you're only allowed to buy is local to support them.
While there we stayed in a dorm room type chalet about 1.5km from the pub, with 4 rooms and a living room that features a fireplace, the communal toilets, showers and cooking place was located at the end, and there was no gender separation so there was 3 showers 3 toilets open to all sexes.
The nights at Sani gets damn cold, leaving the poorly insulated dorm rooms results in a sudden realisations that one should not leave the dorm room. Anyway walking through the frigid cold to the pub and entering the well insulted pub is one of the best feelings. Being duped into a secret meal not so much
