Bourke's Luck Potholes, Geological formation at Blyde River Canyon, South Africa.

Bourke's Luck Potholes are a rock formation at the confluence of the Treur River and the Blyde River, near Graskop on the R532 in Mpumalanga. Erosion in the red sandstone has cut a canyon that continues into the Blyde River Canyon. Stones swirling in eddies ground deep potholes and basins into the rock.

Gold prospector Tom Bourke discovered these formations in the 1880s while searching for minerals in the area. His name became attached to the site and remains in use today.

The name comes from prospector Tom Bourke, who found a small amount of gold at this spot, though the actual gold reef lay outside his claim. The site is a stop on the Panorama Route near Graskop, and the German name Bourkes Glück Strudellöcher translates as Bourke's Luck Potholes.

Visitors can view the formations from secure boardwalks and viewing platforms positioned at different angles along the rivers. The pathways are well-marked and lead to the best vantage points for observing the details.

Tom Bourke found only a small amount of gold here; the reef that yielded it lay outside his claim. The site takes its name from that find, and the potholes themselves were cut by pebbles spinning in whirlpools at the Treur–Blyde confluence.
