River tubing is an activity conducted in rivers, often confused with rafting. Although both involve rivers, there are significant differences between tubing and rafting. In tubing, participants use inflatable rubber tubes, usually one person per tube, while rafting involves rubber boats. Tubing is typically done in rivers with gentle currents, whereas rafting is done in rivers with moderate to strong currents.
River tubing is one of the main activities in Bukit Lawang. Usually, after hiking, tourists can choose river tubing on the Bohorok River as a way to return to the Ecolodge. This activity is always guided to ensure safety for participants. Along the river, visitors are treated to beautiful scenery, including forests and countryside. If lucky, they may also spot some wildlife. Often, children and local residents can be seen playing or swimming in the river.
