Excursão noturna ao fogo azul da cratera de Ijen saindo de Bali

Mount Ijen, on the border of Banyuwangi and Bondowoso in East Java, hides in its crater the rare "blue fire" of burning sulphur gas, visible only at night, and a turquoise acid lake. You leave Bali in the evening, cross by ferry from Gilimanuk to Ketapang and start walking at 2 a.m. with a local guide: about 2 hours and 3 km up to the rim at 2,386 m, then a steep gravel path down into the crater, with a gas mask, to see the blue flames and meet the sulphur miners. Breakfast at a local warung, then back to Bali. Bring your passport. Not recommended with back or heart problems, asthma, in pregnancy or for wheelchair users. Price per person for 2 people; 80 USD per person for 3–4 people, 150 USD for one traveller.
