Never stayed there, but I did stay at Ames Brook Campground in Ashland. Rated 9.2 out of 10 on RV Life. This is just over an hour southwest of N. Conway. I really liked Ames Brook. Clean bathrooms, friendly campers.
It is about 1/2 hour to Hanneford (large gocery store). There is a smal lgrocery store one and a half miles from the campground, as well as a good church. One hour to the cog railroad, on My Washington. Less than half hour to a great walking and bike trail (I forgot the name). It is a six mile walk or bike ride to the waterfall and back.
I stayed for a month. Could have stayed fortwo.
