Coos Bay North Jetty

The Coos Bay North Jetty stands at the northern side of the Coos Bay entrance on the BLM-managed North Spit, reached by way of Trans-Pacific Lane and its network of dune roads. Options here include drift dives along the outer western portion of the jetty, a protected inner pocket on the north side that suits skills work, and a submerged section of the western rock said to hold relics from earlier wreck-era coast. Reported visibility runs about 5 to 25 feet, and the outer tip grows more demanding the further west a diver ranges.

The rock structure at the entrance is part of the modern jetty era; the paired south jetty was built between 1924 and 1928. Between March 2023 and December 2025, road access to the jetty was closed while the U.S. Army Corps of Engineers completed major rock repairs to the structure, and portions of South Dike, Foredune, and Bayside Road were closed to vehicle traffic through the project. Vehicle access resumed after construction wrapped in late 2025, and current road status on the North Spit is tracked on the BLM's North Spit page.

A rocky reef biome sits along the jetty rock and its invertebrate cover, with a surf zone biome layered across the exposed outer tip and the adjacent sand beach. Scuba and spearfishing are the documented uses here. Strong tidal current at the bar makes slack the safer window, and drift dives typically move from west to northeast on an incoming tide. Winter storms make the outer tip dangerous outright.

Parking is limited to BLM turnouts and dune access along Trans-Pacific Lane; there is no developed lot at the jetty itself, and no dive shop or air fill currently operates in Coos Bay, so the nearest fill service is at Port Orford. The dry-sand beach on the North Spit is a Western Snowy Plover Management Area, and dry-sand foot access is restricted between March 15 and September 15, though wet sand and the jetty rock stay open through the closure. No marine reserve overlay applies, and take is enforced under standard Oregon Department of Fish and Wildlife recreational marine rules.
