Wahkiakum County is located in the southwest portion of Washington, and borders the Columbia River on the south. Wahkiakum, an Indian word meaning “tall timber,” was first settled in 1846. The county has depended on forest products and dairying as its primary pursuits.

A short trip from the coffee bars of Seattle and Tacoma, three major volcanos - Mounts Rainier, St. Helens and Adams - rise like pyramids from the surrounding hills. Residents and visitors alike can climb on the back of a volcano or bike a wooded trail in the shadow of a city skyline. Or perhaps windsurf with the world's best where the breath of the Pacific is channeled in a great gorge.

Cowlitz County covers 1,144 square miles within the southwestern region of Washington. Once known as the “Timber Capital of the World,” Cowlitz County is home to Douglas fir, hemlock and western cedar trees which cover much of its rugged terrain. Cowlitz County still produces a large supply of logs and finished lumber for domestic and international markets, but has become more diversified. Recently, Cowlitz County has become known for its tourist attractions and tourism has become a growing industry. The May 18, 1980 eruption of nearby Mount St. Helens forever changed the landscape and the role tourism plays as an industry here.

Located in southwest Washington, Skamania County covers over 1,000,000 acres of diverse country. Home to the Gifford Pinchot National Forest, Trapper Creek, Indian Heaven Wilderness, waterfalls and mountain rivers, Skamania's southern border is defined by the Columbia River and the Columbia River Gorge National Scenic Area. The northern territory holds the peak of Mount Saint Helens in the west and the base of Mt. Adams to the east. In 1805 Lewis and Clark named Beacon Rock, an 848' core to an extinct volcano, on their journey to the Pacific Ocean.Today it is the favorite day hike for many.
