Visit the popular Hoh Rainforest and hike the Hall of Mosses trail or explore the Hurricane Ridge for scenic views of the mountain ranges.
Known for its iconic Haystack Rock and long sandy beaches, Cannon Beach is a perfect spot for surfing, tidepooling and scenic coastal drives. Visit the art galleries or indulge in fresh seafood at one of the coastal restaurants. Hike through the Ecola State Park trails, which offer picturesque views of the Pacific Ocean and wildlife like elk and bald eagles.
