The range spans some 80 kilometres, with its highest peak of 1,529 metres (note other sources state 1,590 or 1,592 metres) and many cliffs running from northwest to southeast.

Coming to there, tourists are attracted to visit Nui Coc Reservoir. This 2,500ha lake includes 89 islands, concealing mysterious legends. Nearby the lake, Coc Mountain stands imposingly amid the blue sky, the bright sunshine over every blade of grass and twig, all creating marvelous and splendid scenery.
