The Eastern Tepuis (Spanish: Tepuyes Orientales), also known as the RoraimaâÂÂIlú range, is a mountain chain stretching for some along the border between Guyana, Venezuela and, to a small extent, Brazil. It runs in a northwesterly direction from the tripoint of these countries, closely following the GuyanaâÂÂVenezuela border, with a single major peak (Uei-tepui) to the south, on the BrazilâÂÂVenezuela border. Moving northwest from Uei-tepui (2,150 m), the main summits of this chain are Roraima-tepui (2,810 m), Kukenán-tepui (2,650 m), YuruanÃÂ-tepui (2,400 m), Wadakapiapué-tepui (2,000 m), KaraurÃÂn-tepui (2,500 ), Ilú-tepui (2,700 m), and Tramen-tepui. 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. Ilú- and Tramen-tepuis are often treated together since they are joined by a common base.
The Eastern Tepuis chain has a total summit area of about and an estimated slope area of . It includes some of the best known and most widely visited tepuis, particularly Roraima and nearby Kukenán.
