Don't worry if you haven't the time or energy to summit Mt Namúli. Equally memorable is the 8km (one way) hike to the cascata (waterfall) in the hills north of town. Take a picnic, carry plenty of water and allow an easy day for the excursion. A guide isn't required, as you'll encounter plenty of local villagers and tea pickers along the route.
To get there, head first to the UP4 tea factory (also known as Chá Sambique), which you can see in the distance to the north; ask locals to point out the way and allow about 45 minutes on foot. From UP4, it’s approximately another two hours on foot along a winding track through the tea plantations to the falls, which will be to your right. Swimming is possible in the pools above the cascades.
