Its heather-clad slopes and occasionally boggy terrain provide a genuine sense of solitude, rewarding walkers with a quiet, expansive summit overlooking the nearby Rhobell Fawr and the distant Rhinogydd.

Did You Know?
- •The name translates from Welsh as 'Black Slope', derived from 'ddu' (black) and 'allt' (a hillside or wooded slope). This likely refers to the dark, peat-stained heather and the shadowy northern crags that define its profile.
- •Dduallt is frequently climbed alongside its higher neighbour, Rhobell Fawr. The two are separated by a high, undulating col that requires careful navigation, as the ground can be notoriously spongey even in relatively dry weather.
- •From the summit cairn, walkers earn a clear sightline to the sharp profile of Cnicht and the Moelwynion range to the northwest, while the vast, craggy expanse of the Rhinogydd dominates the western horizon.
- •While officially classified as a Nuttall and a Hewitt, the hill is perhaps better known to locals as a place where the lack of a defined path ensures you will spend more time looking at your compass than the horizon.
