Welcome to Interior Sabah
The landscape is dominated by the Crocker Range – home to one of Borneo's toughest treks – which rises near coffee-growing Tenom in the south and runs north to Mt Kinabalu. The range forms a formidable barrier to the interior and dominates the eastern skyline from Kota Kinabalu down to Sipitang. Once across the Crocker Range, you descend into the green valley of the Sungai Pegalan, which runs from the bustling market hub of Keningau in the south to Ranau in the north. The heart of the Pegalan valley is Tambunan – Sabah's rice bowl – a good place to delve into traditional Murut culture. An even better place to do so is Batu Punggul, near the Kalimantan border. Near Tambunan you'll find Mt Trusmadi, Sabah's most challenging peak ascent.
