How many shades of green can you count? Lewis and Clark State Park is a great place to start.

This cool forested space east of Interstate 5 and south of Chehalis offers hiking and horseback riding through a rare stand of old-growth trees on the historic north spur of the Oregon Trail. The park provides an all-American camping experience, with fire circles, an amphitheater and horseshoe pits. Your horse can even camp with you at one of the park's equestrian campsites.

Boundless enjoyment awaits children and families, on lawns that double as playing fields, on miles of trails amidst lush ferns, gnarled snags, nurse logs and in cathedral-like thickets of giant trees.

While buildings and kitchen shelters may be purely functional to the kids, adults and history buffs will appreciate these structures. Lewis and Clark State Park was developed by the Civilian Conservation Corps (CCC) in the 1930s, during the Great Depression, and examples of the characteristic CCC architecture can be found throughout the park.

Don't forget to visit Jackson House State Park Heritage Site, just 2 miles to the north.
