Tambunan is a town in Sabah's Interior Division, located about 70km east of KK City and famed for its nature attractions. Nestled on a fertile plain hemmed in by the highlands of Crocker Range Park, the valley is often called 'Switzerland of the East' by locals for the beauty of its natural landscape and lush paddy fields.
The gateway to climb Mount Trusmadi (2,642 meters above sea-level), the second highest mountain in Malaysia, Tambunan is also home to Rafflesia pricei, an uncommon species of the parasitic flower. A famous waterfall also lies in the area at Mahua Substation. Accessible from KK City through Penampang, Tambunan is also connected between Keningau and Ranau towns.
