The river is tidal as far inland as Stirling, but generally it is considered that the inland extent of the firth ends at the Kincardine Bridge.
There are a number of towns which line the shores, as well as the petrochemical complexes at Grangemouth, the commercial docks at Leith, oilrig construction yards at Methil, the ship-breaking facility at Inverkeithing and the naval dockyard at Rosyth, with numerous other industrial areas including the Forth Bridgehead area, Burntisland, Kirkcaldy, Bo'ness and Leven.
There are impressive vertical cliffs all along the west coast teeming with seabirds in early summer. The island is treeless and rugged, but there are tracks and marked paths which allow you to visit all parts without difficulty. In order not to disturb the nesting birds you are expected to keep to these paths.
