As East Kalimantan’s second-largest municipality, the bustling city of Balikpapan has two important harbors, a tropical climate with an average temperature hovering around 27° Celsius (80 Fahrenheit), and very little variation in rainfall (an average of 20 cm or 8 inches per month). The area around Balikpapan itself is very hilly and the surroundings have both mineral and oil reserves. As a result, several international companies trying to exploit the resources have established headquarters here. Due to the influx of foreign money and the need for a skilled workforce, local authorities have done much to make the city attractive. Nature tourism is quite popular and there are many beaches, a fantastic market full of produce, spices, fabrics, and beads, and a new Botanical Garden has been inaugurated in recent years.
