spot on bongi! everone has given you some great advice especially regarding the trek to the river, also getting to the water is a bit of a maze.
however make sure if you are taking tents chairs, a lot of equipment, you go with a vehicle that can pull you back up that damn hill. we got stuck leaving with my dads jetta as we had a trailer and had to get the farmer with his 4x4 to take the trailer up to the entrance. arrange with the shop before hand and they do it with a smile. otherwise enjoy and i cant wait to go back. let us know how it went.
