About the garden

Owned by
Charles Williams

Caerhays Castle and its 56.5ha (140 acre) gardens are the home of the Williams family. The natural beauty of the coastline and its steep valleys, the architectural surprises, the inescapable sense of history and the range of activities and facilities that the estate offers, all set the scene for a wonderful day of discovery and exploration.      

The gardens originated from the work of plant hunters in China at the start of the 20th century. Caerhays bred the very first Camellia x williamsii and is today the home of a Plant Heritage National Collection of magnolias containing more than 600 species and named hybrids from around the world.      

The gardens have an international reputation and have been described as 'world class'.
