Self guided cycling holidays in Scotland – Speyside and Moray Way The River Spey rises in the hills above Newtonmore in the heart of the Scottish Highlands. It’s the fastest river in Scotland, and as it dashes northwards to the sea, it plays a vital role in salmon fishing and Whisky production. This route follows much of the course of the Spey through a wide range of landscapes with many historical, natural and cultural experiences along the way.
