Today the site consists of an elongated oval, running up a slight slope, with one large chamber at the top of the slope and a smaller chamber beneath the branches of a tree at the lower end. Beside the upper chamber is a solitary standing stone. It seems that the site would originally have offered views to the sea.
The Dyffryn Ardudwy site is signposted rather indifferently. I only noticed one sign, visible approaching from the A496 heading north into the village, with no apparent signs to help those coming from the north.
Parking is problematic; you'll likely have to park on a nearby street and walk. There is a short footpath of a hundred yards leading off the A496 to the burial chamber.
