I have stayed at Charlie’s Beach 4 times for a couple of nights on two different trips to Nootka Sound. Fortunately, unlike Nick, we have had no bad experiences. It can get busy so there is a definite advantage in arriving early and having the best option for your tent site.
There is a rough campsite in the shallow bay on the NW shore of Bligh about 1 1/2 miles south of Carlos Point. I have not camped there but it made a pleasant lunch stop and it had obviously been used by a large group ( outfitter?) for camping at some point.
