Across the valley from Isallt, and a mile or so north from Hendre Ddu, lies Moelfre Slate quarry. It is hidden in woodland above the road and reached by an unmarked public footpath from Pont Gyfyng. The way goes to the left hand side of a farmhouse that was probably the manager's house of the quarry, with the lower mill to the left. This is in "re-use" today, although the water wheel pit and mill building are still evident as such, as are the fine launder pillars. The tallest of these is in use, ironically, as a support for a washing line!

Above this, things become interesting. A run-in adit leads into the bank, while an opencut drives into the hill, next to it a cei mulod or loading bank. In the woods above, we found a shaft, down on the line of the adit. We later found another, flooded adit further to the north- perhaps these were trials to test the viability of the slate. The quarry itself is on the site of earlier metalliferous trials, so these workings may have been in connection with this. As the trackway climbs steeply upwards, a small pit opens out, where slate has been taken, then the working abandoned.
At the highest level and above the workings is a very fine round powder house. We had lunch in this, listening to the bayings of a pack of hunting dogs, quartering the hill above. Soon, we were surrounded by them, but they seemed to have little interest in us.
