I should point out I am far from expert on this subject & my points raised are from my own & others experiences & advice.
I would like to add to this topic.
although it is possible to self drive & stay at lodges I can see little advantage in doing so.
You will miss so very much on game drives, watching for the track to disappear into a gully, watching for a hidden elephant leaves little time for a wider viewing area.
A guide knows the area, animal territories & the such, their ability to spot animals is phenomenal & they have the advantage of the bush-drums from other guides.
So I assume that if you intend to self drive then you intend to camp as well. For me it is the best way to experience Africa & safari.
I offer the following advice.
Take your litter with you. DO NOT bury it! At some sites we spent time clearing other peoples rubbish that had been buried then dug up by animals. By the amount & type I think this was from mobile accompanied safari camps that had booked the sites in the past & not by self drives!.....I hope!
Although I expect it is possible to camp anywhere outside the reserves & parks, camping is only allowed at either private sites or public sites in side. You have to book your pitch in advance & for the migration possibly a year or two in advance!
As long as they know you have booked Wildlife Rangers will take a drive by most days to see if all is OK.
Public camp sites normally have water to wash & toilets, some are only a pit & tin screen, some are tiled with hot water & flush toilets. Each site has limited pitches, on some each pitch is well away from the next & you may never know that others are there till you meet at the toilet "block" which you may have to drive to get to from your pitch.
The draw back is that you could have noisy campers near to you & in some they will be visible next to you only meters away.
There may be but I know of no public camp sites that are fenced, the animals can just walk in & out at will and because of regular use the animals make a point of visiting every day looking for free-bees!
Private camp sites. Again book in advance you have no other campers & you will be the only humans for miles. There are no toilets water or facilities what so ever so it's a bush toilet & if you have the water a bush shower. Animals will pay a visit but it is only a passing interest.
Tents, it is possible to hire a 4x4 with a roof tent fitted my opinion is that each day to game drive you have to pack up camp before setting out & set it all up that night. With a bell tent you can leave chairs, table & tent & be out game driving at dawn without packing up camp first. I do not think you are any safer in a roof tent than a bell tent.
Rules for campers. Remember you are in the African bush! Not on the Costa Del Where ever?
Keep your impact to a minimum, use the "Fire scar" that is there don't light a fire in a new spot, there is less chance of igniting grassland this way & you don't leave another scar.
Take all valuables with you don't leave them in the tent.
Keep all food & water shut in the vehicle inside a sealed container/cool box.
Keep your camp site tidy at all times & your rubbish sack inside the vehicle so you don't attract the local wildlife.
All ways ensure you have a clear route into the vehicle & keep the seats clear in case it is prudent to shelter inside.
Else where on this site is a link to photo's of a bull elephant ( [URL=http://www.bushdrums.com/forum/showthread.php?id=632]Link Here[/URL] ) shot because he had got used to stealing from untidy campers & see what I mean about roof tents!
