A late Easter meant we were treated to some lovely weather last week, so we took a break from renovations and headed over to Trégnanton to check out for ourselves what the excitement was all about…

Originally part of the Nantes-Brest canal, Lac de Guerlédan was created in 1930 by building a dam and flooding an area of about 4km sq to supply hydro-electric power for EDF.

Every 30 years or so the lake is drained to allow for inspections, however due to recent technological advances this is no longer required and  2015 will be the last opportunity in a generation to view the spectacle. During the summer over 3 million visitors are expected to view the empty lakebeds that reveal abandoned houses, ruins and 17 sunken locks..

Although not quite yet empty, the depth and scale of this once flooded valley are still amazing, Check-out my gallery of images taken on iPhone 6 here

The official website gives details of locations of the best viewpoints, parking and facilities together with how to book guided tours of the lakebed.
