About the garden

Owned by
Lord and Lady Arran

Located in the rolling hills of North Devon, the 50-acre garden at Castle Hill is a haven of tranquility surrounding the magnificent Palladian House. Enhanced and tended by Lord and Lady Arran, this beautiful expanse of gardens offers a wealth of sights and scents that change with the seasons. From the pinks, reds and whites of the camellias in the spring to the red, amber and gold of the autumn leaves and a heady scent of lavender through May to July, you can enjoy the gardens at any time of year.  

Wander through rare trees along tranquil paths where magnolias, camellias, rhododendrons and azaleas grow in abundance together with a profusion of daffodils and bluebells among carpets of North Devon primroses. The Millennium Garden is a particular joy to walk in on a sunny spring day with its colourful herbaceous borders that lead to winding pathways into historic parkland interspersed with temples, follies and statues. 

A climb to the sham castle is more than worth it for the panoramic views across to Exmoor, Dartmoor and on a clear day Lundy Island. The track through the magnificent Woodland gardens, filled with a variety of flowering shrubs, leads down to the river and the Ugley Bridge. Perched high on the hill is the newly restored Holwell Temple and as a memory to Lady Margaret Fortescue, The Kennel sits proudly on Oxford Down. No visit is complete without taking in these highlights.    

Dogs on leads and young children are welcome to come and explore the expanse of landscape. Home-cooked food from the tearoom and a calendar of events throughout the season give more than one reason to visit Castle Hill.
