Tarso Toh is an extensive volcanic highland in the northwestern Tibesti Mountains of Chad, distinguished by an extraordinary density of volcanic landforms. Unlike the massive single calderas found elsewhere in the Tibesti, Tarso Toh is characterized by a vast field of scoria cones, maars, and lava flows that create a bizarre and desolate landscape. Its highest elevations reach approximately 2,000 meters above sea level. Geologically, the area is relatively young, with most volcanic structures dating back to the Quaternary period. The maars in this region are often great circular depressions formed by phreatomagmatic explosions, which in the past periodically held small lakes. Today, white sedimentary deposits on the floors of these craters serve as evidence of these wetter periods in Saharan history. Tarso Toh provides scientists with crucial insights into the variety of volcanic eruption mechanisms under extreme arid conditions. The solitude and monumental scale of the highland make it one of the hidden natural wonders of the central Sahara.

📋 Practical info

🧭

Getting there

This volcanic highland is accessible only via unpaved tracks that require the use of a 4WD off-road vehicle. Travelers must prepare for a long desert journey, which typically starts from the larger settlements in the northern part of the country.

📅

Best season

The safest time to visit is during the cooler months from November to February, when daytime temperatures are more moderate. During the rest of the year, the heat can be extreme, making physical exertion very dangerous on this exposed terrain.

⛰️

Terrain & paths

The volcanic landscape consists of solidified lava and rugged plateaus, which can be a challenge for hikers. Surefootedness is essential on the uneven ground, as there are almost no developed roads or marked paths for visitors on the highland.

🎒

What to bring

In addition to durable clothing, carrying ample water reserves and a comprehensive emergency kit is vital. Since there are no facilities on-site, all camping gear and food must be transported in the vehicle for the duration of the trip.

🅿️

Parking

There are no designated parking zones; stopping places are usually only found at improvised campsites near water sources or sheltered rocks. Vehicles should never be left unattended in the completely deserted landscape during the journey.

⚠️

Safety

The greatest danger is losing one's orientation in this vast, uninhabited region, which is why GPS and satellite phones are mandatory. One should only travel in groups to avoid being completely isolated in case of a medical emergency or vehicle breakdown.

⏱️

Time needed

A visit typically takes several days, as the journey alone is very time-consuming due to the difficult terrain conditions. Plan for at least four to six days to safely explore the highland and view the volcanic formations without rushing.
