Edinburgh from wikitravel.org

Understand

Edinburgh is located on the east coast of Scotland's central Lowlands, situated on the southern shore of the Firth of Forth. Edinburgh's landscape is the product of ancient volcanism (both the Castle crag and Arthur's Seat are the eroded plugs of volcanoes) and more recent glaciation (carving out valleys south of the castle and the old Nor'Loch, presently the site of the Princes Street Gardens).
