Grandtully Falls is a well-known whitewater access point on the River Tay near Aberfeldy in Perthshire, Scotland.

The rapid complex comprises several distinct sections — the top falls, middle rapids, Boat Breaker, and fourth falls — making it one of Scotland's premier sites for canoeing, kayaking, and rafting.

Permanent slalom gates are installed along the riverbanks, and the site serves as a regular venue for competitive canoe slalom and wildwater racing, including GB selection events.

Access to the main rapid is gained via a footpath running approximately 100 metres beside the river.

The Scottish Canoe Association operates a campsite nearby, and a separate Forestry Commission access point a few miles upstream provides an additional entry for whitewater racing.

The site is considered suitable for intermediate paddlers at lower water levels and advanced paddlers when the river is running high.
