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.
River Fowey
The river runs through two Sites of Special Scientific Interest (SSSI), one of which is also part of a National Nature Reserve (NNR). The Upper Fowey SSSI is a floodplain on the southern slopes of Bodmin Moor and is designated for its wet heath vegetation and herbaceous valley-floor mire communities. Lower down the river at Golitha Falls part of the woodland is designated a NNR and is within the Draynes Wood SSSI. At this point the river runs through a gorge and is of particular importance for ″lower plants″ such as liverworts, mosses and lichens. Golitha (pronounced "Goleetha") is derived from the Cornish word for "obstruction". There is a 1- riverside walk, from the visitor car park. Golitha Falls is the site of Wheal Victoria copper mine
