Loop D at Cape Disappointment State Park offers 51 campsites near a freshwater lake with amenities including flush toilets, showers, drinking water, and a dump station.

The campground is more protected from wind than other loops and provides convenient access to hiking trails, the Lewis & Clark Interpretive Center, and beaches for paddling and fishing opportunities.

Reservations are highly recommended, especially during peak summer and fall seasons, as this popular coastal park fills quickly.
