The gardens were designed for Sir Rupert and Lady D'Oyly Carte in 1925, and the moist Devon climate makes it ideal for plants that like it wet, such as bamboos, mimosa, and subtropicals. In addition, there are rare trees, walled and terrace gardens, a circular pool and stream gardens, and scented plants and herbs. A gazebo provides excellent sea views.
Coleton Fishacre is good for autumn colours.
The garden and house are now owned by the National Trust, which also administers much of the coastline in the area.
