Welsh water – 24

Friday 17 May, 2024

Welsh water

This walk will visit the 4 linked lake reservoirs in the northern Carneddau foothills which provide water for the coastal towns and the Conwy Valley. We will be taken by our minibus to Cwm Eigiau, from where we will head up 250m to the mountain lakes of Llyn Melynllyn and Llyn Dulyn, before returning by a different path to the Eigiau valley. From here we’ll pass by Llyn Eigiau (the source of the Dolgarrog disaster in 1925) and walk over the hill to the Cowlyd valley, where Llyn Cowlyd’s dam dominates the area. From here we’ll catch the minibus back over the hill to Trefriw. There’s lots of industrial history in these areas too.

This area of the Carneddau foothills is remote, and it can be cold at altitude, even in May. Please ensure that you have good, warm, waterproof clothing and sturdy footwear.

Duration:  All day.  Please bring a packed lunch.

Distance:  About 9 miles / 14 km

Grade:  Moderate/strenuous in view of the terrain (rough in places) and distance (some 1,400 ft / 425 m of ascent)

Please be aware that this is a rural area and that all our walks take us out into the countryside where some parts of paths and tracks will be uneven and sometimes wet and slippery underfoot; it isn’t like walking on pavements!

Departure time:  09:30 a.m. from Trefriw Village Hall (LL27 0JH, SH781631)
Refreshments will be available in the Hall both before and after your walk. (See ‘our cafe’.)  Please stay and socialise!

Walk Leaders:  Tony Ellis & Nigel Thomas
