WALK SUMMARY

The Nantlle Ridge is a stunner, a long (13km), high, winding, view-laden, ridge in the west of high Snowdonia which is famed as one of Wales' finest walks. But it is surprisingly empty considering that.

Beginning at Rhyd-Ddu on the A4085 south-east of Caernarfon, you cross some low ground then climb steeply to gain the ridge at the rocky summit of Y Garn, which is surrounded by cliffs to north and west. Here the excitement begins, the ridge leading initially southward and quickly narrowing to occasional teeters and easy scrambles above the western cliffs. The views towards Snowdon to the east, Anglesey to the north and the Lleyn Peninsula to the west just become better as you climb to two further summits, swinging westward and exchanging rock for luxurious grassy slopes. Really wonderful.

Drop and cross an excitingly narrow neck to climb gently back up to a mountaintop obelisk (to Queen Victoria’s Diamond Jubilee), then descend gently then drop steeply to a col, to climb a craggy slope behind a spine (climbable by thrill-seekers) to the high point of Craig Cwm Silyn at - gasp - 734m. A long (1.5km), flattish mountaintop takes you to a final summit, which is followed by a westward steep and rough descent to meet a gentler track which takes you north-west round at mid-level behind a low hill from Llyn Cwm Dulyl lake to the roadhead near Cors y Llyn.

A truly worthwhile and delightful walk on a reasonable day. Not much point in low cloud.

A reasonable head for heights is needed, but this is not a dangerous or highly exposed trail on a clearish day.

This is demanding walking in mountains with uncertain weather. Come fully prepared, and consider whether tackling it is sensible in poor conditions.

This walk is well written up in the Cicerone book.
