Dolgarrog Disaster

Sunday 22nd May, 2022

Dolgarrog Disaster

This walk heads out of Trefriw up over Cefn Cyfarwydd, the hill behind the village, to the Cowlyd valley.  A steep walk to begin with, but with some stunning 360° views of Snowdonia and the coast. We will then cross in front of the Cowlyd dam and up over the shoulder of Moel Eilio to remote Cwm Eigiau and Llyn Eigiau and its dam. It was the breaching of this dam which caused the disaster in 1925. We will then follow the course of the floodwaters along the old trackbed of the Eigiau Tramway back to Dolgarrog, passing Coedty reservoir, high above the village (and where there are often cuckoos to be heard) before following the waterfalls down to Dolgarrog and visiting the memorial there. We’ll return to Trefriw on our minibus.

Please remember that it can be cold in the foothils of the Carneddau mountains, even in May, so make sure you’ve got warm, waterproof clothing, and good footwear.

Duration:  All day. Please bring a packed lunch.

Distance:  about 10.5 miles / 17 km

Refreshments will be available in the Hall both before and after your walk. (More here.)
