In pictures: Hiking the Sinai Trail

Nour el Din Sherif Sinai TrailNour el Din Sherif
The Sinai Trail began as a 220km (137 mile), 12-day hiking route run by three Bedouin tribes. It opened in 2015, running from the Gulf of Aqaba to the top of Egypt's highest mountain, Jebel Katherina.

Jebel Katherina looms high over hikers on the Sinai Trail. According to Christian tradition, angels carried the body of St Katherine to the top of this mountain when she was martyred under Roman rule. Today, a small, Orthodox chapel sits atop the summit.

The sun goes down behind the Gulf of Suez. The Sinai is a great continental land bridge and from the highest points of the trail, hikers can look west to see the Sun go down behind Africa, waking to see it rise the next morning over Asia.

This year the trail was extended to 550km, taking 42 days to finish. The expansion brought in five additional Bedouin tribes. The tribes have all been marginalised from mainstream tourism, and the trail is a new source of income for them.

The extended trail shows the most beautiful parts of the Sinai to the world and aims to change perceptions that the peninsula is a hotbed for terrorism. Most militant attacks have taken place in North Sinai, which is a closed military zone.

Tribesmen of the Muzeina and Alegat tribes sit in a cave, sheltering from the midday sun. Today, around 50 Bedouin from the eight tribes work regularly on the Sinai Trail as cooks, guides, hosts and traders.

Younger Bedouin work on the trail as apprentices. One of the trail's goals is to create a space where traditional Bedouin knowledge can be passed from older to younger generations, as it always has been. This helps keep it alive, in a real, breathing way for the future.

Younger Bedouin boys come with their fathers or brothers and start off learning to load camels and getting to know the routes, water sources, place names, the stories of the land and all the things a Bedouin needs to guide people safely.

The Garasha and Alegat are two of the Bedouin tribes from South Sinai that will work together on the Sinai Trail. In the distance is the flat tableland of Hadabt el Teeh, the territory of another Bedouin tribe.

The Bedouin form a special bond with their camels, walking with them, feeding them and caring for them when they are sick.
