Swaledale is in the Yorkshire Dales National Park.  There are high mountains at the head of valleys with evocative names such as Blea Barf, Great Shunner Fell and Rogan's Seat, which echo the voices of the Vikings who settled here over 1,000 years ago.  Sparkling moorland streams cascade down the valley sides through pastures touched by a thousand shades of green.  The River Swale, England's fastest flowing river, threads its way through a maze of fields dotted with stone barns.
