Kali Mas

## Overview Kali Mas is a public drinking spring located in the heart of Surabaya, East Java, Indonesia. Situated near the coordinates -7.259655, 112.747684, this spring shares its name with the Kali Mas (meaning "Golden River" in Javanese), a historic canal and distributary of the Brantas River that has flowed through Surabaya for centuries. The Kali Mas waterway has long been central to the city's identity, serving as a vital water source and trade route since the days of the Majapahit Empire. This public drinking spring offers what visitors have described as pristine, raw water — unprocessed and drawn directly from a natural source. In a bustling urban environment like Surabaya, natural springs like Kali Mas provide a rare connection to the region's abundant groundwater resources, fed by the volcanic geology of East Java. The area's fertile soils and mineral-rich aquifers, shaped by nearby volcanic activity, contribute to the character of the water found here. ## Directions 1.

Visitors have reported the water to be clean and pristine in its raw, untreated state. As with any natural water source, conditions may vary with the season — the dry season (approximately May through October) and wet season (November through April) in East Java can affect water flow and clarity. The spring is situated in an urban setting within Surabaya, Indonesia's second-largest city, so expect a mix of city surroundings rather than a remote wilderness experience. The Kali Mas canal area has undergone revitalization efforts in recent years, with improved walkways and green spaces along portions of the waterway. Surabaya's tropical climate means warm temperatures year-round, typically between 25–35°C (77–95°F), so bring water for the journey and dress for the heat. While the spring water has historically been used by locals as a drinking water source, visitors should be aware that raw, untreated water carries inherent risks, and water quality has not been independently verified for this listing.
