Wandering through the formal walled gardens of Aberglasney House, 4 miles west of Llandeilo, feels a bit like walking into a Jane Austen novel. The gardens date from the 17th century and contain a unique cloister built solely as a garden decoration. You'll also find a pool garden, a 250-year-old yew tunnel and a 'wild' garden in the bluebell woods to the west. Several derelict rooms in the central courtyard of the house have been converted into a glass-roofed atrium garden full of subtropical plants such as orchids, palms and cycads.
Inside the gardens, a whitewashed and flagstoned cafe with an outside terrace sells coffee, cakes and snacks.
Aberglasney is in the village of Llangathen, just off the A40. Bus 280 between Carmarthen and Llandeilo stops on the A40, 500m north of the gardens.
