The Eastern Tepuis (Spanish: Tepuyes Orientales[1]), also known as the Roraima–Ilú range, is a mountain chain stretching for some 60 kilometres (37mi) along the border between the disputed territory of Guayana Esequiba in Guyana, Venezuela and, to a small extent, Brazil.[2] It runs in a northwesterly direction from the tripoint of these countries, closely following the Guyana–Venezuela border, with a single major peak (Uei-tepui) to the south, on the Brazil–Venezuela border. Moving northwest from Uei-tepui (2,150m), the main summits of this chain are Roraima-tepui (2,810m), Kukenán-tepui (2,650m), Yuruaní-tepui (2,400m), Wadakapiapué-tepui (2,000m), Karaurín-tepui (2,500), Ilú-tepui (2,700m), and Tramen-tepui.[2] The minor peak of Wei-Assipu-tepui lies entirely outside Venezuela, on the border between Brazil and Guyana. Additionally, there are a number of minor plateaus which form a chain between Uei-tepui and Roraima-tepui.[3] Ilú- and Tramen-tepuis are often treated together since they are joined by a common base.[2]

The Eastern Tepuis chain has a total summit area of about 70km2 (27sqmi) and an estimated slope area of 320km2 (120sqmi).[2] It includes some of the best known and most widely visited tepuis, particularly Roraima and nearby Kukenán.
