Melynllyn & Dulyn Reservoirs
Melynllyn & Dulyn Reservoirs on the eastern side of the Carneddau mountains in Snowdonia. Upon parking we spotted a huge dam wall in the distance with breaks in, so added that at the start, we had to see it. It turns out after researching the dam: “on 2 November 1925, following 26 inches (660 mm) of rain in just five days, the dam broke. The water flowed down to Coedty Reservoir, also causing that to burst, and millions of gallons of water flowed down into the village of Dolgarrog, causing the loss of 17 lives” from: https://en.wikipedia.org/wiki/Llyn_Eigiau
Upon returning to the car park we commenced our walk to the Melynllyn & Dulyn Reservoirs. The walk is uphill most of the way to the Melynllyn Reservoir (wiki info: https://en.wikipedia.org/wiki/Llyn_Melynllyn) on well defined paths, unfortunate for us we chose a day with 40-50mph winds and occasional hail coming straight at us on this section, making it quite a slog to the reservoir. From the Melynllyn you travel down a rocky path to the Dulyn Reservoir (wiki info: https://en.wikipedia.org/wiki/Llyn_Dulyn). From there you then cross very boggy moorland for the bulk of the journey back, the paths are not well defined on this section, but there are a couple of styles and occasional concrete posts marking the way.
This walk has spectacular views, just wished we had chosen better weather, obviously in this area and at this height the weather can also be very changeable – be prepared and well equipped.
