Start at the National Trust car park at Llanerchaeron, near Ciliau Aeron. This countryside circuit links the estate woodland with the eastern edge of Aberaeron, returning through the wooded Aeron valley. Allow about 2 hours 45 minutes for the walk, with extra time if you also visit the house or gardens.
Leave the car park by the woodland footbridge over the Aeron. Follow the rising path through Allt Lan-las towards Lanlas, then the public paths through the fields towards Brynsythi and the lane near Cwm. A short lane section leads to the bridleway running west towards Aberaeron. At Ffordd y Goitre turn towards Bro Allt y Graig, then follow the public woodland path back past Allt Bryn-gwyn and Allt Wig-ddû. Keep to the signed route through the field junctions near Wig Wen. The return enters the estate woods and uses the same pedestrian bridge to reach the car park.
Expect natural woodland paths, grass, farm tracks, stiles, gates and short road sections. There is a sustained climb away from the valley, uneven ground and muddy sections after rain. This is a moderate country walk rather than an accessible garden circuit. Watch for vehicles on the lanes and leave gates as found. Keep dogs on a short lead throughout the National Trust estate and around grazing animals elsewhere. Avoid riverside paths when flooded and follow any local closure signs.
The car park, visitor centre toilets and cafe provide the start facilities. National Trust parking charges and opening hours apply: the current property page lists £4 per car, with member parking benefits. Check the day’s car park closing time before setting off; woodland walking hours and the house and garden admission arrangements differ. The route stays outside the paid house and garden visit.
Route information checked against Ceredigion County Council’s Llanerchaeron circular map and the National Trust estate map and visitor information.
