Pura Ulun Danu Bratan, located by the western banks of Lake Bratan in the Bedugul Highlands at a level of 1239m, is one of the most picturesque and most photographed temples in Bali. Danu Bratan is inside the caldera of the now extinct volcano Gunung Catur. It is one of the main sources of irrigation in the Balinese highlands, and so the temple is dedicated to Dewi Danu, the lake goddess. Pilgrims come to pay homage, and to ensure bountiful harvests.
