Mount Batur is actually just a small volcano, but its setting is in the heart of a huge crater 14km in diameter. Adjacent to the volcano is the large crescent-shaped Batur Lake, all surrounded by the high walls of the crater rim. The sheer size of the crater conjures up images of the massive eruption of the original Mount Batur that occurred tens of thousands years ago.
The volcano is still active today as Balinese all over the island who still remember the great eruption of 1917 will testify. It claimed thousands of lives and destroyed hundreds of temples. Old people might tell you this was "the year when the world shook" Other eruptions have taken place since, forcing the local population to be relocated, along with several of their temples including one of the main Bali temples, Pura Ulun Danu. Initially inside the huge crater, this temple has been relocated to the top of the ridge overlooking it. Here it now offers an impressive view of Mount Batur.
