A hike on the lunar trails of Lake Natron in Tanzania

Lake Natron in Tanzania is a unique destination for travellers looking to get off the beaten track and discover exceptional natural landscapes. Located in the north of the country, this salty lake is surrounded by majestic mountains and is home to a unique biodiversity. A true treasure of East Africa, this alkaline body of water stretches over 58 kilometres.

Its main feature is its depth, which is no more than 50 centimetres! Lake Natron is known for its high concentration of soda ash and chemical natron, which gives it an astonishing and fascinating orange-red colour. These dark red waters sometimes reach 140°C, while the average temperature of the lake is around 40°C. When the freshwater evaporates, what remains is water with a high concentration of saline minerals such as sodium and trona. Spirulina, an algae with a blue-green hue, is found all over the site, providing a pretty colourful spectacle. It's a thriving breeding ground for bacteria and algae.

This geological feature attracts travellers in search of extraordinary experiences, who come here to explore the colourful rock formations that line the lake. The waters of the lake are also home to several species of endemic fish, including the Alcolapia latilabri and the Alcolapia Ndalalani. Although the lake may seem hostile, dry and dusty, Natron is home to some fascinating flora. Don't miss the surrounding area, dominated by towering mountains such as the dormant volcano of Ol Doinyo Lengai.

The real jewel in Lake Natron's crown is undoubtedly its rich and diverse fauna. But the star of the waters is none other than the pink flamingo. In fact, the bacteria and algae it contains provide an ideal breeding ground for the birds. Thousands of them gather here every year to feed and breed, creating an unforgettable spectacle for visitors.

Flamingos, with their pink plumage and slender silhouette, are one of the icons of African wildlife, and to see these majestic birds in their natural habitat is an experience not to be missed. Every year from June to November, the lake region plays host to a fabulous spectacle. More than 3 million Lesser Flamingos flock to the shores of the lake to breed. Most of the eggs of this species of flamingo hatch in Lake Natron. The lake's caustic environment, high temperature and high, inhospitable salinity provide a good barrier against predators.

There's no doubt that the Rift Valley attracted travellers in search of adventure! Its escarpments offer absolutely splendid views and panoramas. Lake Natron lies at an altitude of 609 metres, yet it is one of the lowest sites on the Rift. But as well as the magnificent spectacle of the Lesser Flamingos that love the lake's ecosystem, a visit to the region also offers the opportunity to visit the Masai people. A semi-nomadic tribe of pastoralists, they are the region's most famous residents. The Maasai have developed a close relationship with nature and have adapted their way of life to the harsh environment of the Great Rift Valley.

Travellers can meet members of the tribe and discover their traditional way of life, as well as their local crafts, such as beaded jewellery and colourful fabrics. When you meet them, they will explain their social organisation and customs. The Masai have no books, so they pass on their traditions through age-old songs and dances.

As well as offering an amazing array of flora and fauna, the region is a favourite with walkers. In fact, the area around the lake lends itself easily to walking expeditions. And this is undoubtedly the best way to access the most beautiful panoramas of the Great Rift. The walks are relatively easy, so you don't need to be in Olympic shape to explore the lunar landscapes of Lake Natron. As a refresher, don't miss a dip in the Ngare Sero waterfall at the foot of Mount Ol Doinyo Langaï.

However, Lake Natron is under threat from mining and human activities, which are having a negative impact on the region's fragile ecosystem. The local authorities have taken steps to protect this exceptional site, but it remains essential that visitors show respect for nature and local communities to preserve this jewel of Tanzania for future generations.
