River Tay
The River Tay emerges from Loch Tay at Kenmore, and flows from there to Perth which, in historical times, was its lowest bridging point. Below Perth the river becomes tidal and enters the Firth of Tay. The largest city on the river, Dundee, lies on the north bank of the Firth. On reaching the North Sea, the River Tay has flowed from west to east across central Scotland.
Thames Path
The Thames Path's entire length can be walked, and a few parts can be cycled. Some parts of the Thames Path, particularly west of Oxford, are subject to flooding during the winter. The river is also tidal downstream from Teddington Lock and parts of the path may be under water if there is a particularly high tide, although the Thames Barrier protects London from catastrophic flooding. The Thames Path uses the river towpath between Inglesham and Putney. Historically, towpath traffic crossed the river using many ferries, but crossings in these places do not all exist now and some diversion from the towpath is necessary.
The general aim of the path and the object of occasional path changes is to provide walkers with a pleasant route and access to the river, as much as possible.
The Thames Path provision naturally falls into three distinct areas.
