Los Testigos, also known as the Aparamán range, is a mountain chain in Bolívar, Venezuela.

[1] 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.

[1] The chain is situated entirely within the bounds of Canaima National Park.

Both massifs are located northeast of the Catholic mission at Kamarata.
