Travelling

Samosir is approximately 50 km long and 15 km wide island in Lake Toba, almost as big as Singapore. It is often described as the hearthland of Batak culture. Samosir is actually a peninsula and not an island, as it is divided from Sumatera only by a narrow man-made canal, the Pusuk Buhit Canal between Samosir and mainland, once made by the Dutch. Samosir is a perfect place to relax and cool down. It is beautiful and scenic and very relaxing. Accommodation is extremely cheap, but food rather expensive (according to Indonesian standard). In the end it evens out compared to other major tourist destinations in Indonesia. The island is small enough for visiting everything of interest from any place you choose to stay in.
