Whistle Lake Access provides parking for approximately 10 cars at the trailhead in the Anacortes Community Forest Lands, with a vault toilet available at the trail intersection near the lake.

The access point features a wide, flat dirt road leading to the lake, making it suitable for families and casual visitors, though the loop around the lake includes rockier sections with elevation changes.

The lake offers good shoreline access for swimming and fishing, with multiple entry points along the eastern and western shores.
