From the M4

Follow the M4 to Pont Abraham. Continue on the A48 to Carmarthen. Take the A40 then the A485 to Lampeter. Travel through Peniel, Rhydargaeau and Pontarsais. Turn right at signpost for Brechfa and Llanllawddog.

Travel 1 mile and approx. 400 yards past the church you will see the entrance to Glangwili Mansion.

If you are travelling from mid-Wales through Llandeilo, do not leave the A40 until you reach the first major roundabout at Carmarthen. Some sat-navs have a sense of humour on this route and will take you off-piste!

 
We found the location of the house to be perfect, not only for it’s setting in the beautiful Gwili Valley and Brechfa Forest. It was also centrally positioned as to provide easy access to the stunning places in the area – Tenby, New Quay, St. Davids and The Gower all being a relatively short drive away, plus many other secluded bays and beaches, lovely villages and castles in the area.
