The Bude Canal is what remains of a 35-mile waterway built between 1819 and 1826 to carry beach sand inland for agricultural use as a lime-rich fertiliser. Only the two-mile section through Bude town remains navigable today, but it is a pleasant stretch — wide enough for canoes and small rowing boats, bordered by flat meadows, and ending at Helebridge in peaceful countryside south of the town. The canal towpath is a popular walking and cycling route.
The canal was technically innovative for its time — it used inclined planes rather than conventional locks for the steepest gradient changes, with small iron boats that could be wheeled up the slopes. The Bude Castle Heritage Centre at the canal head has exhibits on the canal's history and the broader history of the town. Canoes and paddleboards can be hired at the canal head in summer. The walk along the towpath south to Helebridge takes about 45 minutes each way.
