Try the following map.
Places To Go - Yorkshire Heli Club
First three below are on the map above;
Kings Croft Hotel, Pontefract - a great little place, very friendly and they don't rip us Yorkshire folk off!
Hazelwood Castle, Tadcaster (recently removed a massive bush from middle of landing area)
Woodhall Hotel, Linton, Wetherby (make sure your sloping ground is up to speed!
Also;
Middlethorpe Hall (York) but they did start charging (always worth asking) and not the best approach.
Holiday Inn, Garforth used to allow Helis but not sure if they still do.
Quality Hotel, Selby Fork.
Squires Milkbar, Sherburn - allow you to camp!
If you need anymore info then email me through the heliclub website (I rarely check PMs).
