(D)The start is the village of Llandrillo in the Dee Valley. The start is the free car park (Grid ref. SJ035371) adjacent to the river in the centre of the village on the north side of the B4401. Exit the car park and turn left (east) along the B4401 forking right just after the village hall on your right. Follow this lane, ignoring the lane on the right, to climb towards some woods. Reaching the end of the tarmac, go through the gate and continue along a walled track that continues to climb with improving views across the Dee Valley to the Arenig mountains. This track is followed for nearly five kilometres to the col at Pen Bwlch Llandrillo (Grid ref. 091366). The climb is steady and there is a good feeling of spaciousness as you gain height. The only notable landmark en-route is the pack-horse bridge (Pont Rhyd-yr-hydd), which is marked on the 1:25000 map.

(1)Reaching the Col you will discover a memorial to a cyclist and also have the opportunity of a quick ascent to the unnamed summit (621m) on the north side of the col. The diversion completed, leave the track you have followed from Llandrillo and turn right along the signed concessionary path and head south for the ascent of Cadair Bronwen. In places the path is a little wet but nothing too bad and you soon reach the cairn that marks the highest point of the mountain. Views are good with the high peaks of Snowdonia probably gaining your attention in clear weather.

(2)Descend south off the summit along sections of recently installed boardwalk to reach the Col at Bwlch Maen Gwynedd. (If you have the energy you can continue straight ahead and visit the summit of Cadair Berwyn. This option adds another 120 metres of ascent and just over 2 kilometres to the walk.) Turn right at the Col and begin the descent to Llandrillo. Where the path forks take the left hand path and descend alongside a stream - Ffynnon Maen Milgi - as far as the conifer plantation, which is visible from the col. Approaching the plantation the path improves to a track.

(3)Care is needed on the next section. There is a path (very wet and boggy in places) that stays close to the stream. It is better to stay with the track and continue parallel to the stream on higher and drier ground. In places the route is not clear and the best advice is to stay above, north of, the reedy grass that indicates wet ground. This route eventually leads to the 473m spot height and track (Grid ref. 053356). Follow this track to reach a fence. Keep the fence on your right and descend to a gate (Grid ref. 043353). Go through the gate and follow the rough track dropping steeply down to Blaen-y-dre-uchaf and a metalled lane. Continue on this quiet country lane into Llandrillo.(A)

Walked this with three families, kids aged 8 - 12. Tough walk for the youngest and the less fit. Lovely views all the way, mostly clear paths. The description was really clear and helpful, especially on the down hill when the path is unclear for a while. Definitely a two pairs of socks walk as the chance is wet feet is high.
