Overview

Sankey Tank is a man-made lake created in 1882 by Col. Richard Hieram Sankey to meet the water supply requirements of Bangalore. The reservoir spans approximately 37 acres and features a stone-lined perimeter with designated walkways. The site is a managed urban park operated by the Bruhat Bengaluru Mahanagara Palike (BBMP). It functions as a significant biodiversity hotspot for migratory birds and local avian species. Visitors can access pedal boats and rowing facilities provided by the Karnataka State Tourism Development Corporation. The tank acts as a critical local catchment area for rainwater collection in the Vyalikaval and Malleshwaram regions. Vegetation includes a mix of eucalyptus, acacia, and indigenous tree species planted along the embankment. The perimeter path provides a leveled track frequently used for morning and evening exercise.

Insider tips

• Arrive early in the morning to observe peak bird activity before the park gets crowded.

• Stick to the paved walkways to avoid muddy patches near the water's edge during the monsoon season.

• Bring binoculars as the floating islands in the center of the lake attract diverse birdlife that is difficult to see from the shore.
