The Elan Valley and surrounding area has five dams/lakes which were constructed to provide water for Birmingham totally by gravity, i.e. no pumps in 70 plus miles!
Plenty of paths to walk along, some challenging.Good roadways to drive along.
Also the old coach road through wild countryside to reach Aberystwyth, or turn off to other interesting places.
Read the book "The Elan Valley Way" by David Milton/Meridian Books which describes a long distance walk from Birmingham to Central Wales.The walk is in 10 stages and deviates from the pipeway interestingly extending the walk to 128.5 miles
