I spent nine days in northern Sumatra. It was a great experience.
The main attractions were the forests with the wildlife. The Tropical Rainforest Heritage of Sumatra is a UNESCO World Heritage Site. It includes Gunung Leuser National Park (Tangkahan and Bukit Lawang), Kerinci Seblat National Park and Bukit Barisan Selatan National Park. The Orangutans, Gibbons, and various monkeys were fantastic to see.
Another interesting area was Berastagi with the Sibayak volcano.
The Karo and Batak tribes in north-central Sumatra are mainly Christian (as opposed to most of Indonesia, which is Muslim). I visited the Karo village Dokan to see their traditional houses.
A visit to the King's Palace in Pematang Purba was interesting.
Lake Toba and Samosir Island was the last stop on the tour of Sumatra. There are a lot of historically interesting things to see in that area.

Lake Toba is a large natural lake occupying the caldera of a supervolcano. The lake is about 100 km (60 miles) long, 30 km (19 miles) wide, and up to 505 m (1,657 ft) deep. Located in the middle of the northern part of the Indonesian island of Sumatra, with a surface elevation of about 900 m (2,950 ft), the lake stretches from 2.88°N 98.52°E to 2.35°N 99.1°E. It is the largest lake in Indonesia and also the largest volcanic lake in the world.
Lake Toba is the site of a massive supervolcanic eruption that occurred 69,000 to 77,000 years ago, representing a climate-changing event. It is the largest known explosive eruption on Earth in the last 25 million years. According to the Toba catastrophe theory, it had global consequences for human populations; it killed most humans living at that time and is believed to have created a population bottleneck in central east Africa and India, which affects the genetic make up of the human worldwide population to the present.
It has been accepted that the eruption of Toba led to a volcanic winter with a worldwide decrease in temperature between 3-5°C (37-41°F), and up to 15°C (59°F) in higher latitudes. Additional studies in Lake Malawi in East Africa show significant amounts of ash being deposited from the Toba eruptions, even at that great distance, but little indication of a significant climatic effect in East Africa.

Churches, Temples, and Cemeteries
Catholic churches are traditionally raw brick, whereas protestant churches have plastered outside walls.
Individuals that own land are buried in tombs on their own land. Depending on the wealth of the family, the burial tombs can be huge and elaborate for wealthy individuals. Some time after the first burial, the bones are excavated and reburied in another tomb, which can be just as elaborate with multiple levels, with the reburial on the second floor. These reburial tombs are used for the whole family.

Ambarita is a small Batak village. It has some historic relics from the pre-Christian era during the rule of the Siallagan kings. Apparently the people there performed ritual cannibalism in the pre-Christian era. When they captured an enemy, the tribal council would determine his fate. When the enemy was sentenced to death, he was executed in this place and eaten.
The traditional houses were separated for men and women. The men's houses had the stairs to the main floor outside, the women's houses had the stairs inside.
