Sonjo is a short trail, taking on two waterfalls, both a cascade of water. Its a good option for less keen hikers as the path is not steep, and the trail is short, taking only 35 minute to reach the 3nd falls, but still passing through pristine rainforest.
This trail is also a popular 2nd hike for those who have done Sanje the day before, and can be done on the way out of the park.
It’s optional to “go and return” via the same path, or cross the water at the 2nd falls, and make a steep 30m up for a couple of hundred meters to the ridge and decend via a different path. Both paths meet the road withing 20m of each other.
The Sonjo trail is also the starting path for those ascending Mwanihana.
