Pillar Lake sits along the Chase-Falkland Road in British Columbia's interior, roughly 11 kilometres northwest of Falkland. The 106-acre lake is easily accessible by vehicle, with a common approach running through Monte Lake and Falkland.

A recreation site managed by Recreation Sites and Trails BC is located at the lake.

The existing boat launch has sustained damage from vehicle access, and visitors are currently asked to hand-launch watercraft only and to avoid backing trailers into the affected area. The lake is known among anglers, particularly for kokanee fishing.

Pillar Park, a separate BC Parks unit, sits directly across the Falkland-Chase Road from the recreation site.
