National Trust – Dyffryn Gardens is a Grade I‑listed Edwardian garden set in the Vale of Glamorgan just outside Cardiff, covering more than 55 acres around the Victorian Dyffryn House, which the National Trust now manages.

The site is widely regarded as the finest Edwardian garden in Wales, laid out by designer Thomas Mawson for the horticulturalist Reginald Cory, and it features a series of themed “garden rooms,” formal lawns, a productive kitchen garden, and a large 22‑acre arboretum with one of the most significant tree collections in the National Trust.

The heart of the estate includes an ornamental glasshouse with cacti and orchids, wild‑flower‑filled meadows, and a small play area and café, making it a popular day‑out destination for walking, picnics, and seasonal events while remaining within easy reach of the city of Cardiff.
