Nehalem Bay

Nehalem Bay State Park encompasses 890 acres on a four-mile sand spit separating Nehalem Bay from the Pacific Ocean near Manzanita on Oregon's north coast. The park features pristine coastal scenery, shore pine forests, and the distinction of being the only Oregon State Park with an airstrip for fly-in camping. Established in 1938, the park provides extensive camping facilities, beach access, and diverse recreational opportunities from beachcombing to horseback riding. The spit's unique position between bay and ocean creates varied habitats supporting rich wildlife including Roosevelt elk, black bears, and numerous bird species. The park serves as a base for exploring the scenic north coast including nearby Neahkahnie Mountain and the charming village of Manzanita.

The park's diverse habitats support exceptional wildlife including Roosevelt elk that browse in meadows and forest edges, sometimes venturing onto beaches. Black bears occasionally appear, particularly in fall when foraging before winter. Harbor seals and California sea lions frequent offshore rocks and the bay, while gray whales migrate along the coast in spring and fall. Bird diversity is remarkable, with over 150 species documented including bald eagles, osprey, brown pelicans, cormorants, various shorebirds, and forest species like pileated woodpeckers and varied thrushes. The bay provides nursery habitat for juvenile salmon and numerous fish species, while tidepools host sea stars, anemones, crabs, and diverse invertebrates. River otters hunt in bay waters, and beavers inhabit freshwater streams flowing through the spit.

The spit's vegetation transitions from beach grasses and dune plants to dense shore pine forests characteristic of Oregon's coastal sand spits. American dune grass and European beachgrass stabilize active dunes, while Sitka spruce and shore pine dominate the forest canopy over understory layers of salal, evergreen huckleberry, and sword fern. Wet areas support Labrador tea, bog laurel, and sundews in unique wetland communities adapted to acidic, nutrient-poor conditions. Beach strawberry, lupine, and sea rocket colonize open sandy areas, while forest edges feature salmonberry, thimbleberry, and blackberry thickets. The flora reflects constant influence from salt spray, sand movement, and seasonal flooding that creates dynamic plant communities adapted to challenging coastal conditions.

The sand spit was formed by longshore currents transporting sand northward along the coast, combined with sediment delivered by the Nehalem River creating the barrier separating the bay from the ocean. The spit continues to evolve through sand accretion and erosion driven by waves, currents, and storms, with winter conditions sometimes dramatically reshaping the beach. Underlying sediments include marine sands and river deposits accumulated over thousands of years since sea levels stabilized following the last ice age. The bay behind the spit was carved by the Nehalem River, which drains the northern Coast Range before meeting the Pacific. Occasional major storms breach the spit or create new channels, though the overall structure has remained relatively stable in recent decades.

The park experiences Oregon's cool maritime climate with mild, wet winters and relatively cool, often foggy summers. Annual precipitation averages 80-90 inches, concentrated October through April, with summer fog frequently reducing sunshine and moderating temperatures. Winter temperatures range from 40-55°F, while summer highs typically reach only 60-70°F due to ocean influence and persistent marine layers. Strong winter storms can bring high winds, heavy rain, and dramatic wave action, occasionally causing beach erosion and temporary flooding of low areas. Spring and fall offer transitional weather with occasional sunny periods ideal for beach walks and wildlife viewing, though visitors should always prepare for rapid weather changes characteristic of the coast.

The Nehalem-Tillamook people inhabited this coastline for thousands of years, utilizing abundant marine and terrestrial resources including salmon, shellfish, elk, and plant foods. The area features in legends of shipwrecked Spanish galleons and buried treasure on nearby Neahkahnie Mountain, stories passed down through generations though never verified by archaeological evidence. European-American settlement began in the late 1800s with logging of the massive Sitka spruce forests, though the spit itself was too sandy and flood-prone for permanent settlement. The village of Manzanita developed in the early 20th century as a beach resort community. Highway 101 construction in the 1930s opened the north coast to increased tourism, leading to the park's establishment to provide public camping and beach access.

Nehalem Bay State Park was established in 1938 during the golden era of Oregon coastal park development, when the state acquired key properties to ensure public access to beaches and scenic areas. The park was developed with extensive camping facilities to serve the growing number of automobile tourists traveling the newly completed Highway 101. The airstrip was added later, creating a unique amenity for pilots seeking coastal camping destinations. Over the decades, the park has been expanded and facilities upgraded, but the emphasis has remained on providing camping and beach access in a relatively natural setting. The park represents Oregon's commitment to maintaining diverse recreational opportunities along its publicly accessible coastline.

The park features four miles of ocean beach ideal for walking, beachcombing, kite flying, and watching spectacular sunsets over the Pacific. The spit's bay side offers calmer water for kayaking, paddleboarding, and fishing for perch, flounder, and crab. An extensive trail network winds through shore pine forests connecting campground loops and providing access to both beach and bay. The airstrip allows fly-in camping, a unique Oregon State Park amenity that attracts pilots from across the region. Horseback riding is permitted on the beach, and the park's open spaces are popular for kite flying. Wildlife viewing opportunities abound, particularly for elk, seabirds, and marine mammals visible from beaches and trails.

The park provides extensive camping with 291 sites including full-hookup RV sites, tent sites, hiker/biker sites, yurts, and even fly-in campsites near the airstrip. Facilities include restrooms, showers, a dump station, picnic areas, and beach access points. The park is located off Highway 101 near Manzanita, approximately 20 miles south of Cannon Beach and 25 miles north of Tillamook. Nearby Manzanita offers vacation rentals, restaurants, and a grocery store, while larger towns provide more comprehensive services. The park is open year-round with reservation systems for peak summer season and first-come camping during quieter periods. Winter camping is possible but requires preparation for storms and wet conditions.

Management focuses on protecting the dynamic sand spit ecosystem while providing sustainable recreation access for thousands of annual visitors. Dune restoration efforts combat erosion from foot traffic and invasive European beachgrass that, while stabilizing, can alter natural dune processes. Wildlife protection measures include seasonal restrictions in elk calving areas and education about maintaining safe distances from bears and other animals. The park works on invasive species control, native plant restoration, and monitoring impacts from climate change including potential sea level rise that could inundate low-lying areas. Partnerships with Surfrider Foundation and other groups support beach cleanups removing marine debris and microplastics that threaten ocean ecosystems. The park serves as an important model for balancing popular coastal recreation with ecosystem protection.
