Lake Toba

On a fertile volcanic plateau that covers much of northern Central Sumatra, lies the lovely Lake Toba, a vast crater lake containing the lush Samosir island (nearly the size of Singapore). The result of a great prehistoric eruption, Lake Toba is one of the highest (900 metres/2,900ft) and deepest (450 metres/1,480ft) lakes on earth.

The best travel tips for visiting Lake Toba

More than 3 million members of six distinct Batak tribes make their homes in the surrounding high country, which stretches 500km (300 miles) north–south and 150km (90 miles) east–west around the lake. Each group has its own dialect, customs and architectural style.

Each of these groups – the Toba, Karo, Pakpak, Simalungun, Angkola and Mandailing Batak – has its own dialect, customs and architectural style.

On the lake’s eastern shore is Parapat, a tourist resort since colonial times. Today it offers deluxe hotels, golf courses, water sports and a refreshingly brisk climate. For most visitors, Batak sights are the main attractions.

The best place to experience Lake Toba’s spell, though, is Samosir, a 1,000-sq km (380-sq mile) island in the lake. Regarded as the original home of the Bataks in Sumatra, and the Toba Batak, the ‘purest’ Batak tribe, boats depart from Parapat for Samosir.

Best things to do in Lake Toba

From golden beaches and Batak scripts to juicy Berastagi passion fruit, the best things to do in and around Lake Toba will surprise you.

#1 Spend the afternoon at the beaches of Cermin or Sialangbuah

The main route from Medan to Lake Toba runs southeast along the coast through the market town of Tebingtinggi and inland to Pematangsiantar. Side roads along the first 50km (30 miles) offer access to fine beaches such as Cermin and Sialangbuah, renowned for its mudskippers that swim like fish and climb trees.

#2 See ancient shamanic Batak scripts at Museum Simalungun

Pematangsiantar, the second-largest city in North Sumatra, is a cool highland rubber and palm oil centre notable for Museum Simalungun, which contains an excellent display of Batak artefacts including pustaha laklak, bark-leafed books containing sacred formulas in Batak script used by ancient shamans.

#3 See the remote Sipisopiso Waterfall from Kabanjahe

A short bus trip from Kabanjahe, north of Sidikalang, is a spectacular viewpoint near the northern tip of Lake Toba that overlooks the remote Tongging Valley and Sipisopiso Waterfall.

#4 Visit a traditional Karo Batak village

In the surrounding area are Barus Jahe, a traditional Karo Batak village, and Lingga, with its massive, pyramid-roofed rumah adat (traditional clan houses), some over 250 years old. A lucky visitor might stumble across a Karo Batak wedding or rice harvest festival.

#5 Try some Berastagi passion fruit

Berastagi is a hill resort and market town with Dutch-built villas and a cool climate. Located between two volcanoes – Sibayak and Sinabung – Berastagi produces fresh vegetables such as carrots, cabbages and tomatoes and is known for its passion fruit, usually made into syrup.

#6 See King Sidabutar’s tomb at Tomok

A 30-minute ride across quiet water, Tomok is home to the carved boat-like tomb of King Sidabutar. In an enclosure opposite the tomb are ritual statues of a buffalo sacrifice. At the end of an avenue of souvenir booths leading from the jetty are dozens of stands selling kain ulos (hand-woven fabric), two-stringed mandolins, ornate woodcarvings, Batak calendars and many other items of cultural interest.

#7 Visit the megalithic complexes of Ambarita

An hour’s walk from the tourist town of Tuk- Tuk are three megalithic complexes. The first is just up from the jetty and is notable for its 300-year-old stone seats and the tomb of Laga Siallagan, the first raja of Ambarita.

If an enemy was captured in Ambarita, neighbouring hilltop complex for an initial conference before moving on to the second, a cluster of stone chairs where the fate of the prisoner was decided.

The third complex is located south of Ambarita and includes a unique breakfast table. Here, the prisoner was reportedly beaten to death, decapitated and chopped up on a flat stone, cooked with buffalo meat, and eaten.

Best time to visit Lake Toba

The best time to visit Lake Toba is during the dry season, which runs from May to September. During this period, the weather is generally pleasant, with little rainfall and plenty of sunshine. This makes it ideal for outdoor activities such as trekking, cycling, and exploring the lake and its surroundings.

Lake Toba Festival takes place on Samosir Island in June or July, featuring Batak art, cultural performances, boat and horse races, and handicrafts exhibitions.

However, keep in mind that this is also the peak tourist season, and the area can get crowded with visitors. If you prefer fewer crowds and lower prices, you may want to consider visiting during the shoulder seasons of April or October, when the weather is still good but there are fewer tourists.

The wet season in Lake Toba runs from October to April, with the heaviest rainfall occurring between November and January. During this time, some roads and tourist attractions may be affected by floods or landslides.
