Lake Toba

Lake Toba is an immense volcanic lake covering area 1707 sq km (bigger than Singapore) with an island in the center. Formed by a gigantic volcanic eruption some 70,000 years ago, it is probably the largest resurgent caldera on Earth. Some studies say it might have been associated with causing previous ice age/climate change.

The island in the middle - Pulau Samosir - was joined to the caldera wall by a narrow isthmus, which was cut through to enable boats to pass; a road bridge crosses the cutting. You get a ferry from Parapat to Pulau Samosir Island, they run every 1-2 hours, the last one at 7:30pm (Rp 7000). Self proclaimed 'Tourist Hunters' may befriend you on the boat but are harmless and often helpful to find things, arrangements etc (Bintang can fix you up with anything). Tuk Tuk is the main town to stay on Samosir.

Lake Toba used to be popular tourist destination but now not many tourist come, which means many services, no crowds, cheap prices and friendly locals grateful for your business. It is a great laid back place to chill out for a few days after jungle trekking etc. The location is very popular with Chinese tourists around the Chinese New Year, when availability drops dramatically and accommodation costs are known to sky rocket.
