Experience the mesmerizing blue flames of Mount Ijen on a two-day hiking trip that’s become a must for adventurous travelers to Indonesia. After a ferry ride from Bali to East Java, you’ll overnight in a hotel before embarking on a pre-dawn trek to witness the ethereal blue fire, a rare phenomenon caused by ignited sulfuric gases. As daylight breaks, climb to the crater rim to catch a breathtaking sunrise and panoramic views over the turquoise lake. Along the descent, encounter local sulfur miners and gain insight into their challenging work. For those preferring a gentler morning, opt for a sunrise-only hike. The USP here is the chance to witness one of Earth’s rarest natural spectacles—an experience that combines physical adventure with raw natural beauty.
