The southernmost of the five campgrounds on Long Island in the Willapa Bay National Wildlife Refuge, Pinnacle Rock Campground is closest to the boat launch at the refuge headquarters. The campground consists of five sites that are split on either side of a small stream: Two sites are south of the stream and nearer the vault toilet, while three more sites sit north of the stream and up on a bluff. Many have direct views of the bay, while a few are tucked away into the dense coastal forest. Depending on the weather, these more sheltered sites may be a more desirable option for campers.
A hiking trail leaves from just south of the southern sites; salal has overgrown the sign marking this trail, so it is difficult to find. Follow this trail for a quarter of a mile to connect with the network of old logging roads that lead north to additional campgrounds and the Don Bonker Cedar Grove Trail or south to High Point. Alternately, head out to the mud flats and Louse Rocks for shellfishing on the public lands just offshore from the campground. Because this campground is on the western side of the island, this is a great spot to enjoy a sunset over the bay. However you spend your days, Pinnacle Rock Campground makes an ideal base.
As is the case with all campsites on Long Island, sites here are first-come, first-served and walk-in. Sites are generally well maintained and come with picnic tables and fire pits. There is no potable water, but the small stream is a viable water source if you have a method of purification. Access to the island is via private boat, and landings are only successful at or near high tide. Visitors approaching the island outside of this tidal window risk being stranded on the extensive mud flats as tides change. Wildlife on Long Island is wonderfully varied, but this does mean that campers should account for food and garbage storage before turning in for the night. Bear canisters are recommended. There are no garbage facilities here, of course, so pack out what you pack in and remember to Leave No Trace.
