SH6446 : The ridge ahead

Overview

Cnicht rises above Croesor in the Moelwynion of Eryri, Gwynedd. Its pointed profile from the southwest has earned it the nickname Welsh Matterhorn, although the summit stands at the end of a longer ridge. The main top is 690.9 m high. The popular Croesor ascent finishes with short rocky scrambles; longer circuits cross remote, sometimes boggy uplands around Llyn yr Adar and the former slate quarries.

Cnicht

Cnicht is a 690.9 m mountain above Croesor in the Moelwynion, within Eryri National Park. Seen from the southwest, its pointed outline explains the familiar nickname Welsh Matterhorn. From other directions, the longer summit ridge becomes clear.

The summit and ridge

The main summit is the middle of three rocky outcrops. Cnicht North Top, at 690.2 m, is a separate summit farther northeast. Views include Moelwyn Mawr across Cwm Croesor, the Snowdon range and Tremadog Bay when conditions are clear.

Walking routes

Croesor is the usual starting village. Its direct ascent becomes steeper near the top and includes short rocky scrambles. Continuing along the ridge towards Llyn yr Adar opens up several longer circuits, but the terrain becomes less straightforward: paths can fade into wet grass and bog, and navigation matters in cloud.

The route choices below describe distinct published itineraries. The Llyn Cwm-y-foel circuit, the Rhosydd quarry circuit and the Moelwyn Mawr circuit have different returns and should not be treated as interchangeable. Approaches from Blaen Nanmor and Beddgelert make longer mountain days through the northern lake country.

Eryri National Park also promotes a 5.5 km Croesor Circular through the surrounding countryside. That route stays below Cnicht and does not visit its summit.

Landscape and history

Hard igneous rocks and glacial erosion helped shape this striking ridge and valley. Croesor grew with the nineteenth-century slate industry; quarry tracks, inclines and ruins remain a prominent part of the landscape.

Planning the walk

Use the designated Croesor village car park and keep access routes clear. Bring supplies for the hill and check seasonal café opening before relying on refreshments. The council lists an on-demand bus service to Croesor, so confirm booking and return arrangements ahead of travel.

Wet rock can make the summit steps slippery. Longer loops require confident navigation across the uplands. Quarry remains are best viewed from surface paths: avoid open shafts, unstable edges and underground workings. Carry suitable mountain equipment and change plans if conditions exceed the group’s ability.

The highest point is the middle of three rocky outcrops. Cnicht North Top is a separate, slightly lower summit farther along the ridge to the northeast.

Terrain & Geology

Steep mountain paths short rocky scrambling near the summit grassy ridge wet and boggy upland ground faint paths on longer circuits old quarry tracks

Cnicht belongs to the igneous landscape of the Moelwynion. Eryri National Park describes harder igneous intrusions surviving as surrounding Ordovician sedimentary rocks were eroded by glaciers. Glacial erosion also shaped Cwm Croesor below the ridge.

Views & Scenery

Moelwyn Mawr across Cwm Croesor, Yr Wyddfa and the Snowdon range, the upland lakes around Llyn yr Adar, and Porthmadog and Tremadog Bay in clear weather.

History & Heritage

Historical Significance

Croesor developed as a nineteenth-century slate-quarrying village. Quarry tracks, inclines and ruined buildings around Croesor and Rhosydd recall the industry that once linked the uplands with the coast. Cnicht’s pointed outline above the valley is widely known as the Welsh Matterhorn.

Getting There & Facilities

Parking

Use the designated village car park in Croesor, around OS grid reference SH631446. The approach roads are narrow. Keep field entrances, passing places and access to homes clear. Confirm any current charges or restrictions on arrival.

Public Transport

Gwynedd lists 99A/99B Porthmadog–Croesor–Rhyd as an on-demand service. Check current operating days, booking arrangements and your return journey with the council or operator before relying on it.

Nearby Facilities
