Lake Toba

The world's largest volcanic lake, with Batak boat-shaped houses and ancient stone chairs on Samosir Island at its centre – perfect for slow travel and easily combined with Medan's Chinese food scene.

Lake Toba (Danau Toba) lies in northern Sumatra, Indonesia. It formed when the ground collapsed after a supervolcanic eruption about 74,000 years ago, and at around 100 km long, 30 km wide and over 500 m at its deepest, it is the largest volcanic lake in the world. The lake sits about 900 m above sea level, so the climate is cool, with daytime temperatures of 20–28°C year-round – bring a jacket for mornings and evenings. Samosir Island, in the middle of the lake, is about the size of Singapore and is the cultural heartland of the Toba Batak people, who still preserve traditional longhouses with boat-shaped roofs, stone sarcophagi of their kings and a distinctive blend of Christianity and traditional beliefs. Key areas: the towns of Parapat and Ajibata on the east shore are the ferry ports; the Tuktuk peninsula, jutting into the lake from Samosir's east side, has most of the guesthouses and restaurants, and the nearby villages of Tomok, Ambarita and Simanindo each have royal tombs, stone chairs or a museum; Sipiso-piso Waterfall is at the lake's northern end. The best season is the relatively dry May–September; from October to April afternoons are often rainy, though the scenery remains beautiful. Getting there: drive about 4–5 hours from Medan's Kualanamu Airport (KNO) to Parapat, or fly to Silangit Airport (DTB) on the south shore and drive about 1.5 hours; from Parapat, ferries take about 30–45 minutes to Tuktuk or Tomok. Plan on 3–4 days, with 2–3 nights in Tuktuk, renting a motorbike or bicycle to circle the island or link the villages. Good to know: ATMs are scarce on the island, so bring enough cash from Medan; most Batak people are Christian and many shops close on Sundays, but attending a church service is a chance to hear moving choral singing; the lakeshore roads are full of bends, so avoid riding at night.
