Immerse yourself in Washington history at Fort Borst Park.
Troops built the Fort Borst blockhouse in 1856 to protect settlers from potential Native American attacks. Though this historic structure never saw any action—the bullet holes on the exterior are from target practice—it still stands today in Centralia’s 101-acre Fort Borst Park. Admire the expert craftsmanship and see if you can count all the shooting loopholes.
Hit the arcade in Chehalis.
Pull those quarters from the ashtray: Time Masheen Arcade in Chehalis is packed with classic arcade games, pinball, pool, air hockey and foosball and earns a high score in retro fun.
Get fishy at Cowlitz Salmon Hatchery.
Lift a 17-pound fiberglass fish, pour “eggs” into a simulated stream and learn how to discern wild-born salmon from steelhead at the Cowlitz Salmon Hatchery's education center in Salkum. You can even watch hatchery workers mix salmon eggs with milt to create the next generation.

Explore a lava tube at Mount St. Helens National Volcanic Monument.
Far from the populated visitor centers you’ll find the Ape Caves at Mount St. Helens National Volcanic Monument. This lava tube, at more than 2 miles, is the longest in North America. With the help of headlamps, spelunkers can explore the underground lava stalactites, boulder piles and an eight-foot-high lava fall.
Visit ancient trees in Mount Rainier National Park.
On the park's east side, Stevens Canyon Road leads to the Grove of the Patriarchs trail, an isolated island where old-growth western red cedars, Douglas firs and western hemlocks—some as big as 25 feet around—stand sentinel, creating an awe-inspiring sight. Some of these giants have been on earth for more than a millennium.
