AI Insight: Optimal ratio of distance to elevation. Accessible for experienced intermediates.

At 1,085 meters, Snowdon (Yr Wyddfa) is the highest mountain in Wales and a true giant of the British Isles. The legendary circular route combining the Pyg Track for the ascent and the Miners' Track for the descent offers an unparalleled journey into the heart of the Snowdon massif. Starting high at the Pen-y-Pass car park, the Pyg Track traces a rugged, ascending line beneath the sheer precipice of Crib Goch, providing stirring views of the mountain’s lakes (Llyns) in the immense eastern cwm. The summit provides panoramas extending across Snowdonia, Anglesey, and even Ireland on a clear day. The return via the Miners' Track descends to the shores of Llyn Llydaw and Glaslyn, bringing you face-to-face with remnants of 19th-century copper mining operations.

Mission Directive / X-Factor

The Mountain Lakes. The 'X-Factor' is the descent via the Miners' Track, where you walk right along the precipitous edges of Glaslyn and Llyn Llydaw. Looking up at the 500-meter vertical wall of Snowdon’s eastern face from the shores of these deep, glaciated lakes creates a profound sense of scale and amphitheater-like drama that is unrivaled in southern Britain.

Hazard Assessment

weather exposure and hypothermiaPRIORITY 1

The summit of Snowdon can be exceptionally cold, wet, and windy, even in mid-summer when it's warm in Llanberis.

MITIGATION: Pack full waterproofs, a warm layer, hats, and gloves. Check the MWIS Snowdonia forecast.

steep scrambling boulder fieldPRIORITY 1

The zigzag path near the junction of the Pyg and Miners' tracks (below the summit) is steep, eroded, and requires hands-on scrambling.

MITIGATION: Take your time, watch your footing (especially on the descent when tired), and use sturdy boots.
