Welcome to the best place – the Forum, Boon
To add to galed, we budget for about 200km per day and translate it roughly to R1/km. Important to remember is that one tends to stand a while at animal sightings for some time while motor still idling which means petrol is being used. You might encounter some roadblocks caused by buffalo herds or elephants where you also had to wait just to name a few examples.
If you plan to camp for 6 days, I would like to recommend staying either in 1 or max 2 camps, if you can get place. Keep watching the availability on the reservations page, because some camp sites become available over time. The cam site is indicated as Camp Site (CK) indicating Camp Site (CK) 6- max people and P – ppowerpoint. If the camp site do not has a ‘P’, it means no power point at that particular site. You pay R250 for 2 persons and then extra per adult and children to a maximum of 6 per camp site.
To add to your budget, remember that there are 3 tol gates on the H4 route that will cost you roughly about R175 in total on your way there and then again R175 back to Jhb, and this for a sedan motor. If you have trailors, then it will cost extra which means that you need to include this in your budget. It excludes the tolroads in JHB.
Because it is your first time, I will recommend you try to book for a place in one of the camps in the south of Kruger i.e. Skukuza, Berg'n Dal (or Malelane satelite camp) Crocodile Bridge, Lower Sabie of Pretoriuskop. You can from these camps easy drive nice circle routes and cover the whole of the south enjoying lots of sightings.
A another option is the central area i.e. Satara, Balule, Maroela (nearOrpen gate) as well as Letaba. Try to get a camp where you could be central to get to a variety of places and not pack up a number of times moving camp. It takes a lot of valuable time while you are staying relatively a short period in Kruger. We stay about 2 nights per camp in the bungalows and found this a bit tiring.
If you need information about specific and interesting places, you are most welcome to pm me.
I am not a camper, hence other forumites will be willing to assist on camping info, but about other info, just let me know.
