Snowdonia Slate Trail Opens New 83‑Mile Loop Through Wales’ Slate Heritage

A new long‑distance route showcases Wales’ industrial past and natural scenery

The Snowdonia Slate Trail (Welsh: Llwybr Llechi Eryri) officially opened as an 83‑mile (134 km) circular walk that links the national park’s historic slate quarries with some of the United Kingdom’s most celebrated riverside and mountain scenery. The route begins in Bangor, loops through the heart of the park and finishes in Bethesda, offering hikers a self‑guided experience that blends industrial archaeology with rugged wilderness.

Route overview and key waypoints

The trail can be tackled in a single week or broken into shorter sections. A typical seven‑day itinerary starts in Llanberis, moves north to Beddgelert, then east through Llan Ffestiniog before heading south to Betws‑y‑Coed and finally back to the start point. Along the way walkers encounter:

• Dorothea Quarry – a sprawling, abandoned complex of railways, cottages and deep cuttings, described as “looming stone towers like Maya temples”.
• Cwmorthin Quarry – noted for its massive spoil heaps; historically it required ten tons of rock to yield one ton of marketable slate and earned the nickname “the slaughterhouse” after a series of fatal accidents.
• Rhiwbach Quarry – accessed via an old tramway incline and home to a well‑preserved engine house from the 1860s.
• River Cynfal gorge – a dramatic, moss‑laden canyon with powerful waterfalls and a rock formation linked to 18th‑century traveller Thomas Pennant’s tale of the magician Huw Llwyd.
• St Tudclud Church – housing the Carausius Stone, an inscribed Roman‑era gravestone.

Historical context of the Welsh slate industry

Slate from the Snowdonia region has been prized for centuries. Legend holds that Edward I used it for roofing Welsh castles, but large‑scale extraction only began in the 1820s and peaked in the 1870s. The boom prompted the construction of a railway to Caernarfon, the installation of steam‑driven pumps, aerial cables and, notably, the last Cornish beam engine in Britain, which could lift 10 gallons of water per second from a depth of 500 ft. The industry’s decline left a landscape of abandoned pits, rusted machinery and overgrown stonework that the new trail now threads together. Oral histories recall that many quarrymen emigrated to the United States in the early 20th century, a migration sometimes dramatized by anecdotes such as a 1901 Christmas‑pudding donation from English workers that briefly lifted morale before further clashes.

Practical information for walkers

• Guided option – Walkers’ Britain & Europe runs a seven‑day, self‑guided version of the Slate Trail. The package includes six nights of accommodation, breakfast, luggage transfers, a digital navigation app and a 24‑hour emergency hotline. Prices start at £890 per person, with departures daily from April to October.
• Fitness level – The route covers varied terrain, from gentle riverside paths to steep ascents such as the Matterhorn‑shaped peak of Cnicht. Hikers should be prepared for rapid weather changes; the author of the source article noted a sudden hailstorm on Cnicht despite clear skies earlier in the day.
• Transport links – Bangor and Bethesda are both served by rail, and the trail passes near the Welsh Highland Railway, offering additional access points.
• Supplies – Villages such as Beddgelert and Llan Ffestiniog provide pubs, cafés and outdoor‑gear shops. The author highlighted a café called Burrito Blasus in Blaenau Ffestiniog as a useful stop.

How the Slate Trail compares to other long‑distance walks

At 83 miles, the Slate Trail is shorter than the 298‑mile Cambrian Way, which it briefly shares sections with along the River Glaslyn. Unlike the Cambrian Way’s continuous high‑level ridge walking, the Slate Trail intersperses industrial sites and low‑lying river valleys, offering a more varied cultural experience. Both routes demand good navigation skills and contingency planning for adverse weather.

What is confirmed and what remains uncertain

Confirmed: the trail’s length, start/end points, major waypoints, historical facts about the slate industry (e.g., 1820s‑1870s production peak, Cornish beam engine specifications) and the details of the Walkers’ Britain & Europe package. Uncertain or anecdotal: personal stories such as the “magician’s pulpit” or the exact number of workers who emigrated to the United States are drawn from historic travelogues and local lore; they add colour but cannot be independently verified.

Verifying the information

Readers can confirm the trail’s official description, itinerary options and pricing on the Walkers’ Britain & Europe website, and review the Guardian’s original travel feature for the author’s first‑hand observations: https://www.theguardian.com/travel/2026/oct/29/snowdonia-slate-trail-walk-north-wales.
