Marine Drive

Stay Safe

In Oregon, a bicycle is legally considered a vehicle, and the same Oregon road laws apply. Please “be seen” and practice safe riding. Vehicle traffic, farm equipment and narrow shoulders exist on many Oregon roads, and you may find that construction projects, traffic or other events may cause road conditions or signage to differ from the map results, ride descriptions and directions. For travel options plus weather and road conditions, visit, call 511 (in Oregon only), 800.977.6368 or 503.588.2941. Routes listed on this website are for informational purposes and intended as a reference guide only.

Marine Dr runs along the top of the dike that protects the Portland Airport area from floods. You’ll find many places to scan the Columbia River for loons, grebes, and diving ducks, as well as Osprey and Bald Eagle. A paved multi-use path that runs alongside the road. Parking areas all along the way offer many viewing points, but one of the most popular birding destinations is Broughton Beach (3 mi E of I-5, just past Salty’s Restaurant). Park in the large gravel lot on the S side of the road, cross, and take the path E. The 1.25 mi walk to the Sea Scout Base passes through a small but productive patch of short-grass habitat on sandy soil, which is a wintertime magnet for American Pipit, Horned Lark, Western Meadowlark, and rarely Snow Bunting or Lapland Longspur. The river here is also good for water birds: five species of grebes have been seen. Short-eared Owl is sometimes seen along the beach or hunting over the airport grounds in the winter. Be alert that traffic along Marine Dr is dangerous, as drivers go fast on the narrow road.

Marine Dr can be reached from Exit 307 off I-5, or by taking the 122nd Ave or 223rd Ave exits N from I-84.
