Glen Feshie is a wild remote valley deep in the Scottish Highlands along the lower reaches of the northward-flowing River Feshie, a tributary of the River Spey.  The River Feshie rises from the ridgeline of the north watershed of the thousand-meter  (about 3,300 feet) Grampian Mountains.  The river first flows down through  the dense Glenfeshie Forest and eventually enters the more open glen in  question.  About 1½ miles below the tiny village of Feshiebridge it flows  into the River Spey at a point considerably above the broad valley called Strathspey.
 
While the river itself is somewhat longer, the  glen with the magnificent 4,000-foot Cairngorm Mountains towering to its east is  only about ten miles long.  One stretch of the  river are particularly "braided," i.e. divided into multiple interlocking  channels.
