Moel Eilio

Moel Eilio

Overview

Moel Eilio rises to 726.2 m above Llanberis on the north-western side of the Yr Wyddfa massif. Its grassy ridge continues over Foel Gron and Foel Goch, with a return down Maesgwm or a longer horseshoe over Moel Cynghorion.

Summit

The 726.2 m high point is featureless ground 30 m east of the windshelter, at SH 55608 57709. Ground 30 m northeast at SH 55632 57726 is of similar height; ground beside the shelter is 0.3 m lower.

Three-summit circuit from Llanberis

From Snowdon Mountain Railway station in Llanberis, use lanes, fields and bridleway to Bwlch y Groes. Climb Moel Eilio’s north ridge and visit the high ground 30 m east of its shelter, then cross Foel Gron and Foel Goch to Bwlch Maesgwm. Descend the Maesgwm bridleway; take the connecting track across Afon Goch, cross the railway and turn downhill on the Llanberis Path to the start. The complete circuit is 13.44 km; allow 4–5 hours. Beware Foel Goch’s steep, eroded descent.

Full Moel Cynghorion horseshoe

From Llanberis lakeside car park (SH577605), take lanes to Bwlch y Groes. Visit Moel Eilio’s high ground 30 m east of the shelter, cross Foel Gron and Foel Goch, then climb Moel Cynghorion from Bwlch Maesgwm. Descend to Bwlch Cwm Brwynog and follow Afon Arddu through Cwm Brwynog. Pass the lodge on boggy ground, take its track and the footbridge near the ruin, return via Afon Hwch, the youth hostel lane and Llanberis. The full circuit is 16.6 km with 965 m ascent; allow 5–7 hours.

From Bwlch Maesgwm, returning down the bridleway instead of continuing over Moel Cynghorion shortens the day. The full-horseshoe distance does not apply to that shorter option.

Terrain and safety

Grassy ridges, steep eroded paths, lanes and bridleways; boggy ground and less distinct paths on the longer Cwm Brwynog return. The north-ridge climb and descent from Foel Goch include steep, eroded ground that can be slippery. Open slopes require careful navigation in mist; keep away from steep ground beside the ridge. The full horseshoe returns through boggy Cwm Brwynog on a path that becomes less distinct. Watch for mountain bikes on the shared Maesgwm bridleway. Snow and ice can turn these grassy slopes into a winter mountain walk requiring suitable skills and equipment. Check the mountain forecast, visibility and daylight before setting out.

Access and facilities

Use a public pay-and-display car park in Llanberis. The full horseshoe starts at the lakeside car park, SH577605; the shorter circuit starts near Snowdon Mountain Railway station. Allow for the walk from your parking place. Upper-lane parking is very limited; do not obstruct gates or farm access. Check current tariffs on site. Sherpa’r Wyddfa S1 links Llanberis with Caernarfon and Betws-y-coed; S2 links it with Bangor and Pen-y-Pass. Check the current timetable and last return service before travelling. Llanberis has shops and cafés. Gwynedd lists year-round public toilets near the lake, at Maes Padarn and at Y Glyn, with RADAR-accessible facilities. Carry food and water for the hill walk. Check Natural Resources Wales access restrictions and local signs before travel.

Landscape and history

The north-west Snowdon survey area around Moel Eilio contains mainly Cambrian and Ordovician sedimentary rocks. Igneous units also occur elsewhere within that wider survey area. Its elevated ridges have gritty, acidic soils, while lower hollows include seasonally waterlogged, peaty ground. Oxford Archaeology North recorded a prehistoric cairn on Moel Eilio, surviving beneath a later walkers’ shelter. The surrounding valleys also preserve evidence of medieval seasonal upland settlement and farming. Leave cairn stones undisturbed.

Views and nearby summits

In clear weather, views extend across Yr Wyddfa, the Glyderau, the Nantlle Ridge, Mynydd Mawr and towards Anglesey and the Llŷn Peninsula. Foel Gron (629 m), Foel Goch (604.5 m) and Moel Cynghorion (674.2 m) lie along the ridge system.
