Blyde River Canyon Nature Reserve (or Motlatse Canyon Provincial Nature Reserve) is situated in the Drakensberg escarpment region of eastern Mpumalanga, South Africa. The reserve protects the Blyde River Canyon, including sections of the Ohrigstad and Blyde Rivers and the geological formations around Bourke's Luck Potholes, where the Treur River tumbles into the Blyde below. Southwards of the canyon, the reserve follows the escarpment, to include the Devil's and God's Window, the latter a popular viewpoint to the lowveld at the reserve's southern extremity.

The Mogologolo (1,794 m), Mariepskop (1,944 m) and Hebronberg (1,767 m) massifs are partially included in the reserve. Elevation varies from 560 m to 1,944 m above sea level. Its resort areas are F.H. Odendaal and Swadeni, the latter only accessible from Limpopo province. The area of approximately is administered by the Mpumalanga Parks Board.

Bourke's Luck Potholes

This geological feature and day visitors' attraction, named after prospector Bernard Thomas Bourke (brother of Eddie Bourke), is situated at the confluence of the Treur and Blyde Rivers, on the reserve's western boundary . The reserve's nature conservation headquarters is located here, beside the village of Moremela, at the canyon's southern, or upper reaches. Bourke's Luck Potholes marks the beginning of the Blyde River Canyon.

Sustained kolks in the Treur River's plunge pools have eroded a number of cylindrical potholes or giant's kettles, which can be viewed from the crags above. It was named after a local prospector, Tom Bourke, who predicted the presence of gold, though he found none himself. The pedestrian bridges connect the various overlooks of the potholes and the gorge downstream.

The Three Rondavels

The Three Rondavels are three round, grass-covered mountain tops with somewhat pointed peaks. They quite closely resemble the traditional round or oval rondavels or African homesteads, which are made with local materials. Sometimes they are also called the Three Sisters, though this may confuse them with a similar threesome visible from the N1 road in the Northern Cape, very far to the south.

The names of the peaks commemorate a 19th-century chief, Maripi, and three of his wives. The flat-topped peak adjacent to the rondavels is Mapjaneng, "the chief", who is remembered for opposing invading Swazis in a memorable battle. The three rondavels are named for three of his more troublesome wives – Magabolle, Mogoladikwe and Maseroto. Behind the rondavels the distant high plateau of Mariepskop may be visible. Beside the dam, the isolated Thabaneng hill is known as the "sundial" or "mountain with a shadow that moves". It is said that the position of its shadow indicates the time of day.

On a clear day the lookout point provides extensive views. From here one looks over the canyon to the Three Rondavels on the other side, which is flanked on various sides by promontories of the northern Drakensberg range.

The formation of the attractive sedimentary formations are explained geologically as the slow erosion of underlying soft stone, leaving exposed the more resistant quartzite and shale that form the rondavels.

God's Window

God's Window is a popular vantage point along the Drakensberg escarpment, at the southern extremity of the Nature Reserve.

Here, sheer cliffs plunge over 700 metres to the Lowveld. From this escarpment—a mostly unbroken rampart of cliffs—opens a vista into the Lowveld expanse and escarpment forests, the Eden-like aesthetic appearance of which prompted the name. On a clear day it is possible to see over the Kruger National Park towards the Lebombo Mountains on the border with Mozambique.

God's Window features prominently in the plot of the 1980 cult film The Gods Must Be Crazy. Near the end of the movie, the Bushman character Xi (played by Namibian bush farmer N!xau) travels to God's Window, and due to some low-lying cloud cover believes it to be the end of the Earth.

The original Window is a rock that is set further back on a private farm and due to quarry operations and tree plantation farming, this actual rock that looks like a square window could not be used. The site was moved by the government to the edge of the escarpment.

A viewing platform near the car park gives extensive views down the gorge to the plain below.

Fauna

The high plateaus are inhabited by mountain reedbuck, baboon troops and rock hyraxes. Impala, kudu, blue wildebeest, waterbuck and zebra roam the wooded lowveld area. Hippo and crocodile are present in the Blyderivierpoort Dam.
