Located on the south channel of the River Suir at Suir Island in Clonmel, the Clonmel Canoe Slalom Course is the longest purpose-built slalom course in Ireland.

Opened in April 2017, the 300-metre course runs from Lady Blessington's Weir to Denis Burke Park and features 25 gates strung above white water created by rock groins, islands, and ledges placed in the river channel.

It has hosted national competitions and training camps for the Irish Slalom Team. Access to the course is provided via ramps on Suir Island and on the south bank at Denis Burke Park, roughly 200 metres from the Suir Island car park.

Beginners on the Suir Blueway are advised to enter the river downstream of the slalom course. Optimum water levels for paddling the course run between 0. 5 and 0. 7 metres; above 0. 9 metres the course begins to flush out.
