Tourism in the Udzungwa Mountains national Park revolves around hiking and trekking, as the park has no roads and is accessible only on foot. The hiking trails range in difficulty from the short one-hour Sonjo trek to the extremely challenging 6-day camping trek the Lumemo Trail. The most common walk is the Sanje Waterfalls trail which takes approximately four hours to complete and allows the visitor access to the stunning 170 m waterfall and includes swimming in the waterfall plunge pools as part of the activity.
