Make sure you bring a camera to capture the flowing cascades of Air Terjun Hengahenga. If it's raging, you may be able to feel the mist on your face.
This cascade of water is on the to-do lists of many travelers to Luwuk. But Air Terjun Hengahenga isn't the area's only highlight. Kilo Beach, and Tontouan Waterfall are some other interesting sights close by.
