Kollimalai and Singam Isaimini are open to visitors throughout the year, but the best time to visit is during the monsoon season, which typically lasts from June to September. During this time, the waterfall is at its peak, and the surrounding landscape is lush and green.

To reach Singam Isaimini, visitors can take a short trek from the Kollimalai town, which takes about 30 minutes to an hour. The trek is moderately challenging and offers stunning views of the surrounding landscape.
