The common Spanish name Salto Ángel derives from his surname. In 2009, President Hugo Chávez announced his intention to change the name to the purported original indigenous Pemon term, on the grounds that the nation's most famous landmark should bear an indigenous name. Explaining the name change, Chávez was reported to have said, "This is ours, long before Angel ever arrived there ... this is indigenous land."However, he later said that he would not decree the change of name, but only was defending the use of Kerepakupai Vená.
Sir Walter Raleigh in his expedition to find the fabled city of El Dorado described what was possibly a tepui (table top mountain), and he is said to have been the first European to view Angel Falls, although these claims are considered far-fetched. Some historians state that the first European to visit the waterfall was Fernando de Berrío, a Spanish explorer and governor from the 16th and 17th centuries. Other sources state that the first westerner to see the waterfall was the Spanish explorer Fèlix Cardona in 1927.
Angel's plane remained on top of the tepui for 33 years before being lifted out by helicopter. It was restored at the Aviation Museum in Maracay and now sits outdoors on the front of the airport at Ciudad Bolívar. The first recorded European to reach the base of the falls was the Latvian explorer Aleksandrs Laime, also known as Alejandro Laime to the native Pemon tribe. He reached the falls alone in 1946. He was the first to reach the upper side of falls in the late 1950s, by climbing on the back side where the slope is not vertical. He also reached Angel's plane 18 years after the crash landing. On 18 November 1955, Latvian independence day, he announced to the Venezuelan newspaper El Nacional that this stream without any known local name should be called after a Latvian river, Gauja. The same year, this name was registered in the National Cartographic Institution of Venezuela. There is no convincing proof that the indigenous Pemon people had named the local streams, as Auyán-tepui was considered to be a dangerous place and was not visited by the indigenous people. However, lately the Pemon name Kerep is used as well.
Laime was also the first to clear a trail that leads from the Churún River to the base of the falls. On the way is a viewpoint commonly used to capture the falls in photographs. It is named Mirador Laime in his honor. This trail is used now mostly for tourists, to lead them from the Isla Ratón camp to the small clearing.
The official height of the falls was determined by a survey carried out by an expedition organized and financed by American journalist Ruth Robertson on 13 May 1949. Robertson's expedition, which began on April 23, 1949, was also the first to reach the foot of the falls. The first known attempt to climb the face of the cliff was made in 1968 during the wet season. It failed because of slippery rock. In 1969, a second attempt was made during the dry season. This attempt was thwarted by lack of water and an overhang 120 metres (400 ft) from the top. The first climb to the top of the cliff was completed on 13 January 1971. The climbers required nine and a half days to ascend and one and a half days tto rappel down
Angel Falls is one of Venezuela's top tourist attractions, though a trip to the falls is a complicated affair. The falls are located in an isolated jungle. A flight from Maiquetia Airport or Puerto Ordaz or Ciudad Bolívar is required to reach Canaima camp, the starting point for river trips to the base of the falls. River trips generally take place from June to December, when the rivers are deep enough for use by the Pemon guides. During the dry season (December to March), there is less water seen than in the other months.
