The Regency of Buleleng is situated in the northern part of Bali and the largest area among eights regencies in Bali. Geographically, it is on the hill, covering almost one third of the Bali area. On the alluvial slopes of the hills covered in rich volcanic ash which is rich with mountain streams, tropical forest, coffee, clove plantations, prehistoric tree-ferns, wildflowers, creepers and orchids. While on the plain, rice, soybeans, peanuts, maze and tobacco are planted. On the north, Buleleng is bordered by a stretch of coast line of around 144 kilometers in length. Generally, the beaches consist of black coloured sand. For those who dislike the colour of the sand, this colour is off-set by its calm sea suitable for skin-diving and snorkeling to enjoy coral reefs teeming with a variety of colourful tropical fish, just a few meters off the shore. Two lakes appears to be a twin lake, Lake Buyan and Tamblingan are located in the Regency Buleleng. Compared with the south, the north receives less rain due to its location on the rain shadow of the mountain ranges.
