The River Isla (Scottish Gaelic: Abhainn Ìle) is a tributary of the River Tay, running approximately 46 miles (74 km) through Kirkton of Glenisla and Strathmore in Angus and Perthshire, Scotland. The river drains into the Tay and passes through agricultural lowlands as well as wooded stretches, offering varied paddling character along its length.

One documented touring section runs approximately 11 km between Meigle and Couttie Bridge near Coupar Angus in Tay Country, Perthshire. This stretch is rated moderate in difficulty and is suitable for paddlers with some prior kayaking experience; it is considered appropriate for ages 12 and up. The first roughly 3 km of this section passes through forested terrain with numerous meanders and tree-lined banks, followed by a slower, more open stretch of river for the remaining distance to the takeout.

The put-in for this section is near Meigle, and the takeout is at a small layby on the southeast edge of Couttie Bridge. The layby is accessed via the A923 road from Blairgowrie toward Coupar Angus; after crossing the bridge, the layby is on the left. Paddlers are advised not to block the farmer's access at this point.

The wooded upper portion of this section is known habitat for kingfishers, beavers, and otters. The river is prone to flooding in winter, which can result in river blockages such as fallen trees or debris that paddlers may need to navigate around or portage.

Paddlers should come prepared with warm, non-cotton clothing and footwear suitable for getting wet. Dry bags are recommended for carrying spare layers, food, camera equipment, and medications. Given the river's flood-prone nature in winter, conditions and potential obstructions are worth considering when planning a trip during that season.
