Y Fron, also known locally as Cesarea, after the chapel, is a country village on the south-west side of Moel Tryfan,[1] overlooking the Nantlle Valley, in North Wales, near Rhosgadfan and Carmel, on the tail of Mynydd Mawr, with epic views of Trum Y Ddysgl and Craig Cwm Silyn.

In 2002 the Moel Tryfan quarry was used to film Lara Croft Tomb Raider: The Cradle of Life.

The historic 'Cesarea' Chapel was demolished in 2009 and Capel Bwlch-Llyn is now the only surviving religious building left standing in the village.

The village attracts many walkers throughout the year, who begin their venture towards Mynydd Mawr and eventually around Snowdonia and onto Trum Y Ddysgl and Craig Cwm Silyn.

The race begins with registration at the local school, Ysgol Bronyfoel, and continues to the peak of Mynydd Mawr, which is approximately 3.75 miles, rising 1500'.
