Lake Bratan is the second-largest lake on the Indonesian island of Bali. It's over a thousand feet high and is a volcanic crater which has filled up with water. To get there, you need to catch a minibus leaving from Ubud or the coast. On the road, we went down to see monkeys at the temple dedicated to the goddess Dewi Danu. You can go visit by boat or from your hotel or directly by bus if you're arriving from another coastal town. I arrived at the hotel in low season when it was almost empty and there was no staff. I even had to use the hotel's kitchen to cook my food, but I didn't mind. You can negotiate the price of the stay, as well.
