We do a lot of camping all around the East Coast. Swansy lake campground, has a good location and the people are nice, but they have clearly prioritized profits over maintenance.
It needs about a 1000 trees taken town. The roads need to be maintained and widened. The main drawback is the lack of bathroom facilities and showers. In the campground, there's absolutely nothing. (well, there are a few old fashioned dirt outhouses) And across the street, a 5 minute walk there is a small shower facility with coin operated showers two each and a real toilet. Considering the profits from hundreds of campsites (that were full) this level of no facilities is inexcusable.
That said, we had no problems overall and the beach area was very well maintained.
