Grandtully Slalom is a well-established canoe slalom site on the River Tay, situated between the villages of Grandtully and Strathtay in Perthshire.

The river here runs at grade 2–3 whitewater, is approximately 30 metres wide, and features permanent slalom gates strung across a natural rapid. Water levels significantly influence the difficulty, making it a demanding venue at higher flows.

The site is managed by Paddle Scotland, which holds a lease with the landowner and operates the slalom infrastructure.

Use of the gates is restricted to registered members of Paddle Scotland or one of the other Home Nations paddle associations, and check-in is required before paddling.

The site is accessible year-round and regularly hosts competitive slalom and kayak cross events organised by clubs such as Breadalbane Canoe Club.
