Graythwaite Hall, near Hawkshead, Cumbria in the Lake District of England is the home of the Sandys family. The gardens within the grounds are open to the public from early April until mid August, However, the hall is closed to the public.
One of the more famous members of the family was Edwin Sandys, who was Archbishop of York (1576–88) and was founder of Hawkshead Grammar School which William Wordsworth attended. The hall dates from the 17th century and extension work was carried out in the 18th century. In the 19th century some major refacing gave the hall a Gothic Revival or Tudor Revival appearance.
The house is surrounded by 7 acres (28,000 m2) of gardens laid out by Thomas Hayton Mawson from 1886 for Colonel Thomas Sandys. The importance of the commission in Mawson's development as a landscape architect has been discussed by garden historians, and was acknowledged by Mawson himself in his book The Art and Craft of Garden Making (1900). Graythwaite is designated Grade II* in the Register of Historic Parks and Gardens of Special Historic Interest in England.  The gardens are probably best viewed in late spring when the rhododendrons and azaleas are in bloom. However, the Dutch garden and the former rose garden (Mawson's design for the latter has been altered) add interest in other seasons.
The ornamental iron gates at the entrance to the formal gardens were designed by Dan Gibson, a local architect, who also designed the house at Brockhole near Windermere. The gardens are set in a wooded valley. An arboretum contains some fine trees. The woods surrounding the estate were a favourite walking spot for William Wordsworth, and were the backdrop for Beatrix Potter's story 'The Fairy Caravan' .
