Tieni-Siabli lies in the Tonkpi Region of central-western Ivory Coast, roughly midway between Man and the Liberian border. The nearest substantial town is Man, about 70 kilometres to the east and reachable by bus from Abidjan (a journey of roughly 10 to 12 hours). From Man, bush taxis and shared vehicles operate toward the smaller towns of the highland area, but connections to Tieni-Siabli specifically are infrequent and may require hiring a vehicle.
The roads in this part of Ivory Coast vary in quality and can deteriorate significantly in the rainy season (April through October). A high-clearance vehicle is advisable for the final approach. This is off-the-beaten-track travel and should be treated as such — carry extra food, water, and fuel.
