Hi Martyn
I usually stop there each June (Appleby Horse Fair week), the site is packed to full capacity then. All the facilities are kept immaculately clean, plenty of room between pitches. They have a shop which stocks basic caravanning equipment, food, newspapers, alcohol etc all reasonably priced. There is a takeaway which is reasonably priced too. Also has a cafe but I haven't tried that so can't comment.
Outdoor pool which is a bit on the cold side but is clean and well kept.
Decent children's play area.
I think it's a really nice place, pitch prices are pricey in my opinion (only been at high season) but well worth it.
Hope the above helps.
Lisa
