Kalsubai, Mountain summit in Ahmednagar district, India.

Kalsubai rises 1,646 meters (5,400 feet) above sea level as the highest point in the western mountain range and shows steep sections of dark basalt rock. Steel railings and chains run along exposed passages and help with the climb through rocky sections.

The name comes from Kalsu, a Koli girl who worked in a Patil's house and, after being made to scrub pots, left to live on the mountain. The Kalsubai-Harishchandragad sanctuary around the peak was declared by the Maharashtra government in 1986. The Bhandardara dam, built between 1910 and 1924, created Arthur Lake below.

The summit shrine holds a small temple of Kalsubai, the tribal girl from whom the mountain takes its name; about three people fit inside. Below the last ladder, two footprints carved into the rock are revered as Kalsubai's own. A newer temple on the first terrace serves those unable to reach the top.

The round trip starts in Bari village and covers 13.2 kilometers (8.2 miles), with the climb typically taking five to six hours. Start early in the morning to avoid heat and bring enough water as no sources are available along the way.

After the monsoon, wildflowers bloom along the slopes and cover the laterite rock with bright colors. The protected area also holds high-altitude forests where rare bird species nest.
