Walk Nantmor Valley, Llyn Dinas and Cwm Bychan, 11 miles.

This delightful walk starts and finishes at Nantmor Car Park, near LL55 4YG. Free to National Trust members or £4 per day, free toilets.
OL17 map Snowdon and a compass are essential for this walk.

  1. Turn left out of car park, then left into Nantmor village.

  2. Turn left at chapel and walk up tarmac lane to Carneddi gate.
    Carneddi was the home of Ruth Janette Ruck, who wrote the very readable Hill Farm Story and Place of Stones, about life there in the 1950s and 60s. These books are still available secondhand at reasonable prices from Abebooks.co.uk

  3. Walk in front of Carneddi and head south, following footpath signs to Ty Mawr, an important and very well-restored small-scale hall house, dating from the mid 16th century.

  4. Head north east and cross the Afon Nantmor at a ford.  Turn left onto a forest road.

  5. Continue for about two miles through a quiet, very pleasant valley with good views, to a signposted footpath on your left, next to a prominent new house (If you go as far as a left bend in the road, you have gone too far.  Turn back).

  6. Walk carefully across boggy fields, heading for Coed Llewelyn, a plantation of tall conifer trees.

  7. Head downhill through woodland to the lakeside path at Llyn Dinas.

  8. Turn left and walk alongside the lake, until you reach the path to Cwm Bychan.

  9. Long climb up well-made steps, over a stile, then more uphill. Good views of the Llyn Peninsula coast. Pass the remains of an aerial ropeway, which was used for moving copper ore from Cwm Bychan copper mine to Nantmor.

  10. Rest at the commemorative seat, visitors’ book in box under the seat.

  11. Good path back down to Nantmor car park.

Feedback October 2020…
Thank you for posting such a great route that included ancient woodland, a mountain river and streams, a lake, industrial archaeology, beautiful views of Snowdon, and the sea.
Although we began the walk in the rain, but undercover of woodland, the day ended with warm sunshine.
