Southwest Washington

Updated October 3, 2026

Southwest Washington runs from the Long Beach Peninsula on the Pacific east along the Columbia River to the Gorge and Klickitat County, and north past Mount St. Helens to the farm towns of Lewis County. Vancouver anchors it, right across the river from Portland.

7 counties: Clark · Cowlitz · Klickitat · Lewis · Pacific · Skamania · Wahkiakum
See all six regions on the map

Seven counties make up the region on the state road map: Clark, Cowlitz, Klickitat, Lewis, Pacific, Skamania and Wahkiakum. That puts Vancouver, Longview and Centralia in the same region as Mount St. Helens, the Columbia River Gorge and the beach towns of the Long Beach Peninsula.

Use this page as the index. If you know where you are headed, start with a town guide. If you are going somewhere smaller, scroll down to the towns without a guide of their own, where every coffee shop, market, museum, golf course and local business we list is filed under its town.

What Southwest Washington is known for

Mount St. Helens

The 1980 eruption left a crater and a blast zone you can see from viewpoints on several sides of the mountain. Some approach roads have been closed by slides in recent years, so check road status before you go.

Visit Mount St. Helens

Ape Cave

A lava tube on the south side of Mount St. Helens that you walk through in the dark. Bring two light sources and a warm layer, even in August.

Hike the Ape Cave

The Long Beach Peninsula

A long run of open beach with kites, razor clams and small beach towns, from Ilwaco and Seaview to Oysterville.

The Columbia River Gorge

The Washington side of the Gorge runs along SR 14 through Stevenson and White Salmon. Beacon Rock is the climb that gives you the whole river.

Vancouver is by far the largest. Longview, Camas and Battle Ground follow, with Centralia and Chehalis the hub of Lewis County.

Is Mount St. Helens in Southwest Washington?

Yes. The crater is in Skamania County and the west side approach runs through Cowlitz County, both in this region.

Is Vancouver, Washington close to Portland?

Yes. Vancouver sits right across the Columbia River from Portland, Oregon, and the two are linked by the I-5 and I-205 bridges.

Cathlamet on the Columbia, Ilwaco and Oysterville on the Long Beach Peninsula, Stevenson in the Gorge and Ridgefield north of Vancouver are good places to start. The small towns section above lists every town we cover that does not have its own guide yet.

Washington State Parks need a Discover Pass. Mount St. Helens and the Gorge also have federal sites with their own fees and passes.
