Hi All, just booked our Aug 18 holiday at Primrose Valley Yorkshire. Lovely private caravan so using park as more of a base to explore. Don't mind travelling but preferably not more than an hour at a time. Me, DH & 7yr old DS. Any suggestions on good trips that aren't a waste of money? Definately looking at booking a fossil hunt trip as we'd all love that. Don't mind picnics e.t.c to keep costs down. Any thoughts please?
