Lake Toba, another of Indonesia’s natural wonders, is a lake and a supervolcano. It is thought that a catastrophic eruption caused the lake, which is located in a crater, to originate between 69,000 and 77,000 years ago.

The lake is 450 metres deep and 1,145 square kilometres in size. Here, volcanic activity is still frequently observed, and some islands have been raised above the water.

A study in beauty and the strong forces shaping the globe can be found in Lake Toba. You can swim, water ski, canoe, or fish here, or you can just stroll through the neighbourhood on foot or bike.

Mount Krakatau

Undoubtedly, the 1883 eruption of Krakatau, the most well-known volcano in Indonesia, was the biggest eruption ever recorded. The eruption had a significant impact on global climate conditions and had a terrible impact on human life in the surrounding islands of Java and Sumatra. The newest of the islands created by the 1883 eruption, Anak Krakatau, or “Child of Krakatau,” made its way to the surface in 1930.

This immature, unstable volcano keeps rising higher out of the water and erupting significantly. Tourists can visit Anak Krakatau for a reminder of the awesome, unseen power that exists beneath the surface at every turn in Indonesia. Anak Krakatau still emits smoke and fire.
