The Danakil Depression in northeastern Ethiopia is one of the most extreme and inhospitable places on Earth. Located at 125 m (410 ft) below sea level, the area is about 200 km (124 mi) by 50 km (31 mi) and was once part of the Red Sea. The temperature in the Danakil Depression is often above 50°C (122°F), making it one of the hottest places on Earth.
The landscape of the Danakil Depression is made up of salt flats, lava fields, and hot springs. The area is also home to some of the hottest lakes in the world, with temperatures reaching up to 70°C (158°F). The water in these lakes is so hot that it can burn your skin if you touch it.
The Danakil Depression is also home to a number of active volcanoes, including Erta Ale, which is one of the few volcanoes in the world with an active lava lake. The area is also home to a number of salt mines, where salt is mined from the ground and used for a variety of purposes.
Due to its extreme temperatures and harsh environment, it is not recommended to visit the Danakil Depression without a guide. It is also important to note that visitors must be accompanied by armed guards due to the presence of bandits in the area. Despite this, the area remains a popular destination for adventurous travelers looking for an off-the-beaten-path experience.
