The farm has lovely views and a steam railway running through it

Clogwyn y Gwin occupies almost 1,100 acres of the mountain and reaches almost to its summit.

The recently-restored tourist attraction the Welsh Highland railway runs across the farmland.

The farm has been put on the market with a �750,000 price tag after the death of its last farmer owner.

Eleanor Harper, daughter of a former president of the National Farmers' Union, Lord Woolley of Hatton, farmed at Clogwyn y Gwin alone for the four years it took to sell their old family home after they bought the Snowdon property in 1990.

Mrs Harper was a writer on farming issues featured in the HTV series The Snowdon Shepherd in 1997 but died two years later. Now her children and husband are selling up.

The farm runs a flock of 700 sheep and a small herd of Welsh black cattle.

It also encompasses the Welsh Highland Railway whose track runs from Caernarfon through to Rhyd Ddu, just south of the farm.

The volunteer-run steam locomotive railway line carries around 50,000 visitors annually

Last autumn the Welsh Assembly Government announced �5m of funding to restore the final section of the historic scenic railway, taking it to Beddgelert and through to Porthmadog. The extension is expected to open in 2009.

Sales agent Tim Barter of property surveyors Carter Jonas said it was a "tremendous opportunity to acquire a substantial working hill farm, of tremendous scenic and environmental value".

"Clogwyn y Gwin is an absolutely awe-inspiring part of the Snowdonia landscape," said Mr Barter. "The farm is likely to appeal to a wide range of prospective buyers from farming, conservation and lifestyle sectors of the market".
