Every city has its hidden secrets and the Water of Leith Walkway is one of Edinburgh’s. The Water of Leith is a 12 mile narrow river running through the city from the outer suburb of Balerno in the south-west of the city right through the sea near the Royal Yacht Britannia. Alongside it runs a walking path. Since 1988, management of the river has been in the hands of the Water of Leith Conservation Trust who organized keep the river clean and its banks well-maintained. Lovely for walking along in other words.
