I'll start
Home Farm in Anglesey here
Went with 5 other families and took up one whole area of the site.
Able to pitch our tent which is large - Vermont XL.
Very clean toilet and shower blocks with free hairdriers. Also had a bath for children which was fab.
Great play area with a fence around.
Tennis court was also good.
Def go back.
Swallow Falls, Betws-y-Coed here
Not bad - shower blocks Ok at start of weekend but yukky by the end.
Had a play area but not fenced off at the end near the road so I was on edge about that.
Wouldn't go back.
