One of the main attractions in Bandung is the volcanic craters at Tangkuban Perahu. There are many small shops selling souvenirs near the main crater which is known as Kawah Ratu (Ratu Crater). A trail along the rim leads you to the other side of the crater. It is an interesting walk. Don't miss it. A casual walk while taking photos may take about half an hour to reach the other end. Highly recommended for nature lovers.
