Los Testigos, also known as the Aparamán range, is a mountain chain in BolÃÂvar, Venezuela. It consists of four rather small tepuis, forming a bridge between the giant Auyán-tepui to the west and Ptari-tepui to the east. The four major peaks of Los Testigos are (west to east): Aparamán-tepui (2,100 m), Murisipán-tepui (2,350 m), Tereke-yurén-tepui (1,900 m), and Kamarkawarai-tepui (2,400 m), the latter three sharing a common slope area. There however remains some confusion in the literature regarding the names of these peaks.
The Los Testigos chain has a total summit area of around and an estimated slope area of (the collective slope area of the three eastern tepuis being around , with the isolated Aparamán-tepui contributing a further ). The chain is situated entirely within the bounds of Canaima National Park.
In line with and to the west of the Los Testigos chain lies the Los Hermanos massif, which consists of two upland peaks: Amaruay-tepui and Padapué-tepui. Both massifs are located northeast of the Catholic mission at Kamarata.
