One of the things guests tell us they love most about staying at Lodge Dinorwig is stepping outside and being immediately in the mountains. No driving, no faff — just lace up and go. Here are our favourite runs, straight from the front door.
We’re tucked into the hillside above Llanberis, which means the trails start before you’ve even had time to second-guess your kit choices. Whether you’re after a quick hour on the legs or a full day out, there’s something here for every type of runner — and on a weekday morning, you’ll likely have most of it to yourself.
The Llyn Padarn Loop — the warm-up classic
Distance: ~10km | Underfoot: Mixed path and trail | Difficulty: Easy
A loop of Llyn Padarn, taking in the slate quarry, ancient oak woodland, and views back across the lake to Yr Wyddfa. Perfect as a shakeout run the day after something big, or as an evening leg-stretch after a long drive up.
This one starts literally from our gate. Head down the track towards Llanberis, pick up the lake path, and you’re away. We can draw it on a map over breakfast if it’s your first time.
The Elidir Horseshoe — quarry, ridge, and reservoir
Distance: ~14km | Underfoot: Slate track, quarry path, grassy ridge | Difficulty: Moderate–challenging
This is one of our favourite runs from the hostel. Head up through the dramatic terraces of Dinorwig Quarry — once the second largest slate quarry in the world — climbing through its vast, otherworldly landscape of slate ledges and derelict buildings before gaining the ridge to the summit of Elidir Fawr. From the top the views open up across Eryri and down to Marchlyn Mawr reservoir sitting in the cwm below. The return follows the ridge above the reservoir, completing a horseshoe that feels far more remote than the distance suggests. This run is extra-special during sunset hours. So grab your headtorch and go explore.
Moel Eilio — the quiet ridge across the lake
Distance: ~14km | Underfoot: Grassy ridge, good paths | Difficulty: Moderate–challenging
Moel Eilio sits across the lake from the hostel, which means you drop down into Llanberis first before heading up onto the mountain — a gentle warm-up before the climbing begins. Once you’re on the ridge the rewards are immediate: views all the way to Anglesey on one side and deep into the Snowdonia peaks on the other. It’s a proper mountain run without the crowds you’d get on Yr Wyddfa — even on a Saturday. The descent back into Llanberis is fast and satisfying. Time it right and grab an ice cream in Llanberis before heading back up to the hostel.
Yr Wyddfa Explorer — up the Llanberis Path, down the Pyg Track
Distance: ~16km | Underfoot: Well-maintained path, rocky in places | Difficulty: Challenging
This is a big one — a proper point-to-point exploration of Wales’ highest mountain. Head up via the Llanberis Path, the most runnable of the Yr Wyddfa ascent routes, reaching the summit at 1,085m. From the top, descend via the Pyg Track to Pen y Pass — a more technical and dramatic descent that takes you past Glaslyn and down into the pass. From Pen y Pass, jump on the Sherpa bus back to Llanberis and you’re home for dinner.
It’s a big day out and one that many mountain races use as their template — the same route appears in various forms in events across the Welsh calendar. We’re happy to chat through timings and conditions over breakfast before you head out.
Midweek tip: Yr Wyddfa on a Tuesday or Wednesday is a completely different experience from a weekend. No queues at the summit, far fewer people on the paths, and you’ll actually be able to take in the view from the top.
A note on conditions
The mountains here change quickly. A beautiful morning can turn within an hour, and the higher routes — particularly Yr Wyddfa — require proper navigation skills and mountain experience. We always encourage guests to check the mountain forecast at mwis.org.uk before heading out, carry a map and compass (not just a phone), and tell someone their plan. We’re always happy to chat through routes over breakfast.
Lodge Dinorwig is a 4-star hostel above Llanberis. We do proper breakfasts, packed lunches, homecooked dinners — everything a trail runner needs.
