If you're looking for an adrenaline-filled adventure while on holiday, Mount Ijen is more than worthy of your bucket list. Hike up the slopes of this active volcano and you will be rewarded with a mesmerizing view of the turquoise-coloured sulphur lake, the largest acidic lake in the world, that sits within Ijen Crater.
But the real magic of Ijen is only visible after dark, when you can witness its iconic electric-blue flames dazzling against the night sky. This natural phenomenon is caused by the combustion of sulphuric gases as they seep from cracks in the volcano at high pressure and temperature and come into contact with air.
Sit at the crater's edge and marvel at this sight. Stay and enjoy the breathtaking silhouette of the mountains at sunrise. A must-do in Banyuwangi for a truly unforgettable experience.
