Carreg Cennen is a beautiful CADW* site with stunning views, great ruins and a gentle uphill stroll. The track up to the castle is suitable for sturdy pushchairs, and perhaps off road wheelchairs, however there are a number of shallow steps to enter the castle itself. On site there are toilets, a cafe and a shop (and even a wedding venue!).
*there is a charge to enter the castle grounds unless you have CADW membership
