Tamblingan Lake is a beautiful lake located on the north slope of Mount Mortar, Munduk, Buleleng, Bali. This lake is one of the three twin lakes that formed in a large caldera. To the east there is a row of Lake Buyan and Lake Beratan. On the edge of the Tamblingan Lake there is a Gubug Temple. As Lake Tamblingan lies 1,000 meters above sea level, the climate here is cool. The early morning mist that hangs over the waters strangely enhances its mystical appeal. By Lake Tamblingan near Lake Buyan along the south-north highway live a host of monkeys. These multiply so fast, that they are often called the teeming monkeys of the jungle.
