The Vaughan family live and farm high on the hillside of the Gwaun Valley. Their farmland encompasses the rounded peaks of the Preseli hills, and this is where Land of Dreams - Mounting Pressure' takes us in the fifth programme of the series.

It's a harsh existence but one that the Vaughan family has taken as a challenge, rising to it with innovation and sheer hard work. In the 80s, farming's buzz-word was diversification, and this is what the Vaughan family did. Where other families diversified into catering, tourism or conservation, they moved into all three, creating a wonderful, colourful country garden and tearoom. Considering the remoteness of the farm, and the fact that it stands 600 feet above sea level, it was a bold move, but one that worked. Today, this is an award-winning tourist attraction, drawing up to 10,000 people a year from all over the world.

It's a valuable source of income, and so are the other ventures the family share between them. Unusually, the father Dilwyn Vaughan is the one in charge of the home, the housework and the cooking. He cares for his grand-daughter and does the catering for their tea shop and gardens. His heart is in farming, but ill-health has forced him to take a less physical role. His wife Susanne is a carer, the eldest son Robert farms at home and younger son Richard is a full-time ranger for the National Park, as well as helping out in the farm and garden in the evenings and weekends. Robert's wife Sam also goes out to work as a teacher.

"The garden started out as a part-time business - farming being the most important - but it's now developed into a full-time business, really, so it's very important to us," says Richard.

It's not an easy life but it's one they wouldn't change. Even when they're one pair of hands down, as Richard decides it's time he needs to leave for six months to see the world.

What keeps the family together is a deep attachment to the land, the community and to each other, as this programme clearly shows.
