Muar River in the context of "Perak River"

The Titiwangsa Mountains (Malay: Banjaran Titiwangsa, pronounced [ˈband͡ʒaˈran titiwaŋˈsa]), also known as Banjaran Besar (lit. 'main range') by locals, is the chain of mountains that forms the backbone of the Malay Peninsula. The northern section of the range is in southern Thailand, where it is known as the Sankalakhiri Range (Thai: ทิวเขาสันกาลาคีรี; RTGS: Thio Khao Sankalakhiri; pronounced [tʰīw kʰǎw sǎn.kāːlāːkʰīːrīː]).

The mountain range acts as a natural divider, dividing Peninsular Malaysia, as well as southernmost Thailand, into east and west coast regions. It also serves as a drainage divide of some major rivers of Peninsular Malaysia such as the Pahang, Perak, Kelantan, Klang and Muar. The length of mountain range is about 480 km from north to south.

Muar (Muarian dialect: Muo) or Bandar Maharani (Empress Town/City) is a historical town and the capital of Muar District, Johor, Malaysia. It is one of the most popular tourist attractions in Malaysia to be visited and explored for its food, coffee, and historical prewar buildings. On the 5 of February 2012, Muar was declared as the royal town of Johor by Sultan Ibrahim Sultan Iskandar and is the fourth largest urban area (after Johor Bahru, Batu Pahat and Kluang) in Johor. It is the main and biggest town of the bigger entity region or area of the same name, Muar, which is sub-divided into the Muar district and the new Tangkak district, which was upgraded into a full-fledged district from the Tangkak sub-district earlier. Muar district as the only district covering the whole area that formerly borders Malacca in the northern part. Upon the upgrading of Tangkak (formerly Ledang) district, the Muar district now covers only the area south of Sungai Muar, whilst the northern area beyond the river is within the Tangkak district. However, both divided administrative districts are still collectively and fondly called and referred to as the region or area of Muar as a whole by their residents and outsiders. Currently, the new township of Muar is located in the Bakri area.

Muar is one of the cleanest cities in South East Asia, being awarded with Asean Clean Tourist City Standard Award 2017 and 2022.
