Fisher Island is a 920-acre wildlife area accessible only by boat from the Port of Longview's Willow Grove Boat Launch, located just upstream from the ramp on the Columbia River.

The island offers fishing opportunities for salmon and warmwater fish species, plus wildlife viewing of birds and the federally-listed endangered Columbian white-tailed deer (which are protected and cannot be hunted).

Note that vegetation is very dense and difficult to traverse, camping and fires are prohibited, and a Discover Pass is required for access.
