Anton,
The powerpoints are def dodgy. Some are broken, and some have no protection.
Security is what you make of it. I will camp there with the family any time.
The ablutions are far from any camping site. Not a problem for the men or the lucky who have a porta potti, but something to keep in mind.
Fishing...? I am only a beginner :imnew so I cannot comment about that. Some will find it easier than others
I am not negative about this venue, but each to his own. Most prob you will enjoy it.
Louis
