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 particular points of interest. To the extent we have the information, our pages that discuss the relevant sites will note the requirement accordingly.

Rupiah is the official currency on Lake Toba. Prominent merchants such hotels and resorts also accept US Dollars, Australian Dollars, Singapore Dollars and Euros but they convert your money at unfavorable rates. They also take Visa and MasterCard and charge you in the local currency. Smaller merchants such as shops and homestays do not accept foreign money or credit cards.
