We'll start the trail from Sapienza Hut (1.900m alt.) and follow the south ski route we'll go up to Mt Escrivà and then at feet of the New South-Estern Crater as if we could touch it. We'll see the lava flow of 2017 eruption and after a strong slope we'll need a short stop to take energy. Then we'll ready to begin an adrenalinic down in the Montagnola's gorge jumping on the lava sand and we'll be into the Bove Valley, Etna Volcano's Heart. There we could view the great lava sea of 1991-92 eruption and we follow a free track under the Donkey's Back. It is dangerous and amazing at the same time, because there is no path or route but it needs to know the right way if you don't lost on the lava desert. Then we'll go up again to arrive at an external cave formed by "dikes" on the sand.
