The water originates from the Kawah Ijen crater lake, which is known as the largest highly acidic crater lake in the world.
The distinctive yellowish color is caused by high levels of sulfur and metal sulfates dissolved in the water.
The water is non-potable and highly corrosive, making it unsuitable for human consumption or swimming.
The stream flows into the Banyu Pait River, which eventually descends toward the Banyuwangi plains.
Kalipait Waterfall is a unique natural phenomenon where highly acidic, sulfur-rich water flows from the Ijen Crater lake. The water contains high concentrations of sulfuric acid and various minerals, resulting in a distinct yellowish or greenish tint. The stream flows over volcanic rocks, creating a series of small cascades and shallow pools along its course. Vegetation near the stream is often stunted or discolored due to the highly acidic nature of the water. The waterfall is situated within the Ijen tourism area, serving as a geological gateway before reaching the Ijen Crater rim. The acidity level of the water is significant enough to prevent the presence of typical river life.

Do not touch the water, as its high acidity can irritate skin.
Wear sturdy, closed-toe shoes as the surrounding volcanic terrain is uneven and slippery.
Keep a safe distance from the water's edge to avoid slips on wet, sulfur-coated rocks.
Do not attempt to wash your hands or face in the water, regardless of its appearance.
Avoid entering the water; adhere to posted safety warnings regarding volcanic gas exposure.
