The Lisbon Falls are falls in the Lisbon Creek, a right bank tributary of the Blyde River. They are situated a short distance north of Graskop beside the R532 road, and are the highest waterfalls in Mpumalanga, South Africa.[1] The waterfalls are 94 metres (308 ft) high[2] and were named for the Lisbon Creek and the Farm Lisbon, on which the falls are located.
