I just got back from south africa a couple of weeks ago and stayed in Komitieport, just a few k from the Mozambique border and talked to several travelers that had just spent tiime along the coast. They all said it was beautiful but all also had the same story of getting hit up for multiple bribes along the way from police, border guards and one even had to pay a fee when he got his 4 WD stuck in the sand along the coast. The day to day expenses are very low and the seafood along the coast is wonderful. As long as you keep to the backpacker style places I'm not sure you. can go all the way, by road anyway, along the coast. You might get a boat to take you part of the way, I would think it would be inexpensive to hire one localy. It can be slow going once you cross the border and there can be hassles at the crossings, even for South Africans going over for a weekend. This may or may not happen for you, thats one of the things I love about Africa, you never know what to expect and with a little good will and freindly conversation you might avoid or overcome some of the checkpoints and "taxes" or duties that might be levied. My experience this last trip was for a traffic violation that carried a R1000 fine but with a little bargining got it down to R200 and might have gotten it down a lot more but I forgot the extra R100 bill in my wallet so I couldn't show him I had only a few rand on me. Advise, hide all but a few rand and carry that in your wallet in case you get stopped, when you open up your wallet they will generaly make the fine whatever ammount they see that you have on you. Hope your trip is full of adventure, the good kind, and you find your way with very little hassles.
