Popcorn Island Boat Ramp provides boat access to Killarney Lake, one of the deepest chain lakes in the Coeur d'Alene River system.

This small one-acre island features a boat dock, vault toilets, one primitive camp unit, and one picnic unit, accessible by boat only from the nearby Killarney Lake Boat Launch.

The island is open May through September and offers a scenic camping and day-use destination with a wooded, dome-shaped landscape and a trail around the island.
