The River Earn is located in central Scotland, originating from Loch Earn in the southern Highlands and flowing approximately 48 km (30 miles) before joining the River Tay. The river offers a range of conditions that can accommodate different skill levels, from beginners to intermediate paddlers.

The lower and middle sections of the river, particularly around Crieff, are characterised by gentle, easy-going flow through countryside and farmland. These stretches present minimal rapids and obstacles, making them well-suited to those seeking a straightforward paddle. The upper reaches closer to Loch Earn carry more current and include occasional small rapids, providing a more dynamic experience for intermediate paddlers. The river also features occasional small weirs and riffles throughout its course.

Access to the river is relatively straightforward, with launch sites available near the towns of Crieff and Comrie. The water is described as smooth and clear, and the river corridor offers views of hills, forests, and wildlife along the banks.

The river is suitable for both canoeing and kayaking. Those planning trips should note that the upper sections near Loch Earn present more of a challenge, while the sections around Crieff are more appropriate for less experienced paddlers or those preferring a more relaxed outing.
