Neys provincial park campground was originally during World War II a prisoner of war camp which housed mostly German POWs and also some Japanese Canadians between 1941-1946. The camp was enclosed by barbed wire fence and guard towers. It was later dismantled in the 1950's after being used for various other things since the end of the war.
Today, there are plenty of skeletal remains of the original camp scattered through out the current campground which are very easy to find. This includes building foundations, scrap metal, various pieces of equipment, some crushed A-frame roof supports, metal roofing, and even barbed wire in the sand.
All of this can be found in the sections of the park which are closest to the beach. Look between camp sites and beside the trails, beside the main paved road and also further off in some of the sand pits you'll see through out the park
The camp ground visitor center also includes a large archive of information and original photographs.
