We stopped here for just one night in March 2016, and were struck by how peaceful and atmospheric the location is.   Wardens were lovely, and the site is immaculate. Shame there isn't a toilet block, so I imagine that families with children would find more than a few nights stay problematic, with no showering facilities.  I know all vans these days have showers, but for us anyway using our own shower is definitely a last resort, we much prefer to use the Club's showers if available.  It is a small site so probably not feasible.   Magical place nevertheless......
