Loch Spey
The Spey begins at Loch Spey in the Monadhliath Mountains, high enough and quiet enough that the famous river still feels like a private thought. From here it runs north-east, gathering tributaries, speed, names, and human attention on the way to the Moray Firth.
Start here because every later story depends on this small beginning: salmon, whisky, casting, estates, and conservation all need the river before they can become culture.
