Akhfennir and A’jb Allah

Akhfennir is considered the gateway to the Khenifiss Nature Reserve. Nearby is A’jb Allah, also known as Trou du diable: the natural chasm is located about two kilometers north of the municipality of Akhfennir in Tarfaya Province. For geographical orientation, it is important to distinguish between the town and this individual natural site. Its approximate location north of the municipality places A’jb Allah in the vicinity of Akhfennir.

Geology and water

The formation of the chasm is explained by rock erosion, which led to the collapse of the overlying layers. Erosion means the wearing away of rock; the collapse of the upper layers is the next step in this explanation. Together, the two processes form a cause-and-effect relationship that helps explain the natural feature. For travelers interested in the history of the Earth, this offers a concrete way to engage with the natural setting: the formation is not only named but also linked to a geological process. A’jb Allah can thus be viewed as a natural landform with an understandable history of how it formed.

Another aspect concerns the subsurface and water. The subsurface at A’jb Allah is directly connected to the Atlantic Ocean; seawater mixes there with fresh water from rare rainfall that seeps into the ground. This describes two sources of water: the sea and rain that infiltrates the soil. This hydrological aspect complements the explanation of erosion but answers a different question. Erosion and collapse explain the shape of the chasm; the connection with Atlantic and rainwater describes how the water is connected. Those interested in natural processes can consider both perspectives separately.

Legends and planning a visit

Local legends are also associated with A’jb Allah. This storytelling tradition adds a cultural perspective to the geological and hydrological context. The perspectives remain distinct: formation through erosion concerns the landform, while the legends are part of local tradition. If you would like to appreciate both nature and culture on a trip, you can treat the formation of the chasm and its connection to legends as two separate topics. This allows the explanation of the natural feature to sit alongside the stories without one replacing the other.

A report from 2024 described a barrier made of ropes and wooden posts set in concrete at A’jb Allah. Members of the Akhfeniss association network had put it up to ensure tourists’ safety. Check the current situation at the site before visiting.

Hotel and nearby natural attraction

When looking for a hotel in Akhfennir, it helps to plan a visit to the town and a possible trip to A’jb Allah separately: the chasm lies about two kilometers north of the municipality. If you plan to include A’jb Allah, take its location into account and check the current situation at the site in advance.
