Highway 4 between Gerik and Jeli, the Northernmost E-W route in Malaysia and the only one for miles. For that youd think it would be busy, but it isn . Great scenery, especially around Tasik Temengor and over the 1050m pass. There is NO GAS and there are no settlements, so make sure you have enough before leaving either town. There is accommodation at Tasik Temengor.
