One of the most enjoyable excursions from Labé is to the impressive Chutes de Saala, where water cascades down a series of step-like falls in a pretty forest location. The falls are just outside the village of Diari, 30km west of Labé (but the road is bad so allow a couple of hours). You can picnic, swim and hike here and keep your eyes peeled for monkeys or even chimps.
A privately hired taxi from Labé will cost around GFr250,000-300,000.
