The entrance to the glen from the east is below the foot of Buachaille Etive Beag just west of Lochan na Fola, from where waters run west to Loch Leven via the River Coe. The river — Ossian's dark Cona — passes over waterfalls at the Pass of Glen Coe before flowing down to the small Loch Achtriochtan. Loch Achtriochtan is Loch Trychardan (loch of the three friends or relatives) in Timothy Pont's map of the area. After the loch the river turns north west, passing through Glencoe village, before flowing into the sea loch of Loch Leven (a salt-water arm of Loch Linnhe) at Invercoe. The area to east of Lochan na Fola is often classed as part of Glen Coe (see for example the location of Glencoe ski centre), but is in fact part of the upper reaches of Glen Etive.
