Grenadier Pond Access provides entry to the shoreline of High Park's largest and most scenic water feature. The pond covers 14.

2 hectares on the park's western edge and is designated an Area of Natural and Scientific Interest (ANSI) by the Ontario Ministry of Natural Resources, reflecting its ecological value for water birds, fish, turtles, and other wildlife.

A designated stretch of shoreline — running from the Maple Leaf Garden down to the park entrance at The Queensway and Colborne Lodge Drive — is open for fishing under Ontario fishing regulations.

The pond and its surrounding trails are popular with runners, hikers, and birdwatchers. About 70% of High Park is protected natural area; visitors are asked to stay on marked trails and follow all park rules.
