Hotels in North Sumatra, Indonesia
North Sumatra sits on Indonesia's Sumatra island, with a tropical climate that stays around 25°C (77°F) year-round, though the highlands around Lake Toba cool off to about 20°C (68°F) at night. The region is famous for the caldera of Lake Toba, the world's largest volcanic lake, where you can kayak or take a ferry to Samosir Island to see Batak traditional houses. During the dry season from May to September, you can trek through the Gunung Leuser National Park to spot wild orangutans, while the wet season from October to March offers cheaper room rates and lush green rice terraces.
