Lake Toba is a remote area in Indonesia. It is mostly surrounded by hills and mountains, averaging 700 to 1,250 meters (2,300 to 4,100 ft) above sea level. Road conditions are fair in residential areas, but less than so in rural locations. Minivans should handle the rides to most destinations. A 4-wheel-drive (4WD) vehicle or motorbike may be required to access certain points of interest. To the extent we have the information, our pages that discuss the relevant points of interest will note the requirement accordingly.
