Just outside Kintamani, on the rim of the crater, is Pura Ulan Danu Batur, Bali's most important temple after Pura Besakih, dedicated to the goddess of the lake, Ida Bhatari Dewi Danu. Today's temple is actually a reconstruction of parts of the old temple rescued from the side of the crater after the 1917 eruption. It has a meru with 11 tiers reflecting its importance -- the god of Mount Agung has only nine -- and while it is a reconstruction of separate temples, its original form dates to at least the 11th century. Oddly, you cannot actually see the lake from inside the temple. Though this is an important temple, with an important history and place in the Balinese consciousness, there are other more attractively situated temples to visit ahead of this. You will be charged Rp10,000 by the ladies outside with the sarongs if you forget to bring your own.
