Cathlamet is the county seat of Wahkiakum County — one of the least-populated counties in Washington State — and it shows. About 560 people live here, on a bluff above the Columbia River 35 miles west of Longview on WA-4. The streets are quiet, the downtown compact, and the views across the river to Oregon are the kind that remind you how big this river actually is.
What makes Cathlamet worth a detour is mostly wild. The Julia Butler Hansen National Wildlife Refuge flanks the river road west of town, protecting the endangered Columbian white-tailed deer — a subspecies found almost nowhere else — across 5,600 acres of Columbia bottomland. Drive out at dusk and deer in the pastures are nearly guaranteed, along with bald eagles, osprey, and Roosevelt elk.
Puget Island sits just across the Cathlamet Channel, connected by a 1938 bridge. The island is flat, quiet, and good for cycling. At its south end, the Wahkiakum County ferry makes the 10-minute crossing to Westport, Oregon — the last regularly scheduled car ferry on the lower Columbia, running hourly every day of the year since 1925.
In town, the Wahkiakum County Historical Museum covers the Kathlamet people, the fur trade, and the logging and fishing history of this corner of Washington. The Pioneer Church on Columbia Street, built in 1895 and on the National Register of Historic Places, is worth a look on any walk through the compact downtown.
The Elochoman Slough Marina at the base of town offers boat moorage and river access. Early mornings here, with mist on the water and eagles working the current, are genuinely atmospheric.
