Ulu Jelai Dam.

Deep within the forested valleys of the Cameron Highlands, the Ulu Jelai Hydroelectric Project stands as a staggering feat of modern engineering integrated into a rugged tropical landscape. The centerpiece of this 382-megawatt system is the Susu Dam, an imposing 80-meter-high structure constructed from three-quarter million cubic meters of roller-compacted concrete. Rather than flattening the steep terrain, the facility works with it, utilizing a massive network of underground tunnels and a subterranean powerhouse to generate clean energy from the Bertam, Telom, and Lemoi rivers. Located along Federal Route 102, this active infrastructure site is not a typical tourist stop, but it offers a compelling detour for travelers fascinated by how heavy industry and remote, mist-shrouded rainforests intersect.
