Mount Tahan, Mountain summit in Pahang, Malaysia.

This mountain reaches 2,187 meters within Taman Negara National Park, with dense rainforest covering its slopes and multiple hiking trails cutting through the landscape. The paths pass through different ecological zones, each with its own vegetation and wildlife.

In 1905 Leonard Wray Jnr, director of the Federated Malay States Museums, and Selangor Museum curator Herbert Robinson led a collecting expedition of sixty-five men that lasted five months. Dato' To Muntri Idin and Penghulu Panglima Kakap Husin prepared the way. On 16 July 1905 Bulang, Che Nik, Mat Aris, Mu'min and Robinson were the first to reach the summit.

In Malay, tahan means "forbidden", not endurance. A folktale says two giant apes guard two wells on the summit, one of gold and one of silver, whose water turns whatever it touches into gold or silver. Kelantanese call the mountain Gunung Siam, and it is also known as Gunung Rotan, "rattan mountain".

Visitors must register at local police stations and hire certified guides, as the route is demanding and requires careful planning. Prepare for temperature changes that vary significantly depending on elevation and season.
