We stayed 2 nights at Maragowan.  It's well placed for walking into Killin and seeing the Falls of Dochart.  There's plenty of places to eat and drink within the area too, without having to drive.   It seems to be a busy site - the roads were busy with vehicles doing the rounds looking for pitches.  The pitches backing onto the main road seemed to have quite a slope to them so not ideal for motorhomes.  This road also seems popular with motorcyclists and is quite noisy as a result. The toilet block is a bit dated but is warm and clean.  Plenty of showers and toilets. Small play park but the kids all seemed quite happy. Overall, a great weekend but I have to say - whoever decided where to place the motorhome service point should really think again.  The one way system means you have to travel round the site again after filling up, and the same again when dumping water before leaving.  It's also right beside the play park so be wary of children when manoeuvring in and out.
