Big Creek Beach, a hidden gem for agate hunting spot near Yachats, is a spot that can easily be missed while driving along U.S. Route 101. However, the distinctive landmark of the Big Creek Bridge, spanning the creek at milepost 175, makes it easier to locate this scenic destination.
The Big Creek Bridge, with its 180-foot length and a remarkable 120-foot reinforced concrete tied arch, is an architectural marvel. Designed by Conde McCullough, this bridge was completed in 1931 and has played a crucial role in the highway infrastructure ever since. Beyond its functional importance, the bridge enhances the area's aesthetic appeal, showcasing design artistry and adding to the historical landscape of the Central Oregon Coast.
Big Creek originates from Saddle Mountain Spring in the Central Oregon Coast Range and meanders through the Siuslaw National Forest before reaching the ocean. Along its journey, the creek carries minerals and sediments contributing to the beach's diverse composition. This natural process enriches the coastal landscape, creating an environment where beachcombers can discover a variety of minerals and interesting formations along the shoreline.
Cautions: Beware of changing tides, rip currents, driftwood, and sneaker waves. Never turn your back to the ocean.
