River surfing is the sport of surfing either standing waves, tidal bores or upstream waves in rivers. Claims for its origins include a 1955 ride of 2.4 km (1.5 mi) along the tidal bore of the River Severn.[1]
River surfing on standing waves has been documented as far back as 1972 on an artificial wave created on a section of the Eisbach man-made river, a side arm of the Isar River, near Haus der Kunst in the Englischer Garten park in Munich, Germany, today offering the world's largest urban surfing spot.[2][3][4]
