Day 1 : Morning flight from Addis Ababa to Semera, start our day by driving to Erta Ale (which means smoky mountain in Afar language). Erta Ale ranks as one of the most alluring and physically challenging natural attractions anywhere in Ethiopia. It is a shield volcano with a base diameter of 30 km and 1 km square caldera at its summit. Erta Ale contains the world’s only permanent lava lake. It is 613 meters, with a lava lake, one of only five in the world, at the summit. It is notable for being the longest existing lava lake, present since the early years of the twentieth century. Dinner will be served around 17:00 o’clock. After a short break, trek up to Ertale at 20:00 hours. Camels will be transporting all the camping materials and some food (sleeping materials like light mattresses and mat and water) to the rim of the volcano, where we spend the night watching the dramatic action of the boiling lava. You will spend the night on top of the mountain, at the rim of the Volcano.
