Including the wonderfully secluded Llech Sychryd.
From Cardiff, take the A470 to the end of Merthyr Tydfil. From Merthyr Tydfil, take the A465 towards Hirwaun, follow it over the hill. Part way down the other side, about 0.6 miles after the road passes over the Nant-hir reservoir, there is a lay-by that can be used for parking. SN 9811 0639. A similarly placed lay-by on the opposite side of the road may be used by visitors approaching from the other direction.
WARNING: While the waterfall is on public access land, the approach route described in this route guide is not possible at present, due to major road upgrade works. The only known approaches that can be used are from the A470 to the east, or Cwm Cadlan to the north. These are each several kilometres long, either through a network of forestry tracks, or over moorland without paths. This route guide does not cover either of those options.
For best results, locate the landowner of the fields on the left bank of the Nant-hir Reservoir (looking upstream), and obtain permission to cross the fields. Walk up the northern side of the road to the bridge over the reservoir. Immediately before it, cross the fence into the fields below the bridge. Pick up a path heading up the edge of the river's gorge, crossing gates as needed, to reach open access land. Continue following the gorge top, to arrive at the Llech Sychryd waterfall. Take a picnic and enjoy it in the ample space behind the waterfall.
Without access permission, the same point can be reached by walking up to the upper end of the bridge (right bank of the reservoir when facing upstream), on the northern (upstream) side of the road. Hop the fence into the forestry land, and very carefully descend the steep bank to the remains of a wall. Follow it upstream, taking care of the undergrowth and occasionally unfenced drop into the reservoir. Eventually, the going becomes easier, and reaches the top of the Llech Sychryd waterfall.
Upstream, there is another waterfall, which can be awkward to reach. Continue upstream above Llech Sychryd, past the first side stream, to reach the second stream, at the edge of some forestry. Just after the stream, cross the fence into the forestry, and ascend the left bank of the stream, remaining above the stream's gully. The waterfall can soon be heard in the gully. Descend to it when appropriate.
