Discovery Tours : Our signature tours for small groups - we take you to discovery volcanoes and volcanic areas from close with an expert in their field. These tours have a broad mix of activities and interests from photography, walking, study travel, nature & culture.
Igneous or magmatic rocks: The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.
Blue flames of burning sulfur: Ijen volcano in East Java has one of the most impressive sulfur deposits on earth. They are so hot that the sulfur often ignites - a mysterious display at night caught on camera.
