Accommodation in Helderberg is everywhere. You can go and camp at Victoria park or lodge in Lord Charles hotel which by the way has some of the best breakfast in the country and who knows how many awards. We went to eat there the other day and its nice. Out of season the food in the morning seems a bit dry and not so plenty full but the breakfast is still on to remember. There are many guest houses scattered all over Helderberg but there are some of those guest houses that looks more like a 5 star restaurant with interior decoration you cant even think would be in a house.
Coming to Helderberg on holiday is really worth it.
