The Water of Leith, a footpath along the canal, is a long green corridor of almost 20 kilometres that runs silently through the city. Below the road surface, away from the noise of traffic and the city, opens up this bucolic corner that seems to come straight out of a romantic novel of the 1800s. A long pedestrian and bicycle path starts from Balerno and goes as far as the sea, passing through ancient rural villages, now outbuildings on the outskirts of the city, lively suburbs, locks, small waterfalls and hidden and suggestive corners of the city: few tourists visit this place so suggestive, instead very frequented by the inhabitants of Edinburgh as a Sunday walk.
