The Banks-Vernonia State Trail, traversing part of Columbia County, is the first "rails-to-trails" state park built in Oregon. It was developed on an abandoned railroad bed stretching between Banks, in Washington County, and Vernonia. The trail covers 21 miles and features 12 bridges. The gentle grade allows hikers, bicyclists, equestrians and people of all abilities to enjoy the scenic Coast Range mountains, fields and forests.

Rails-to-trails conversions have become popular across the country as more unprofitable rail lines have been abandoned. Rather than break up the right-of-way land into numerous private holdings, states have developed rail-trails as recreational assets. Nationally, there are more than 19,000 miles of rail-trails and around 100 million users per year. (Sources: Oregon Parks and Recreation Department | Rails-to-Trails Conservancy)

History
Columbia County, named for the Columbia River, was created in 1854 from the northern half of Washington County. It covers 646 square miles and is bounded on the north and east by the Columbia River, on the west by Clatsop County, and on the south by Washington and Multnomah Counties. Columbia County was the 16th county created in Oregon and is the third smallest county in Oregon after Multnomah and Hood River Counties.

Lewis and Clark explored this area in 1805-1806. Early settlements were established by fur traders as early as 1810. As American immigration increased in the mid-1840s, lasting settlements began to appear. The Yakima Indian War (1855-1859) drove many Washington Territory residents south of the Columbia River and helped boost the populations of St. Helens and Columbia City.

The first district court met in 1854 in Milton, which served as the county seat until 1857 when it was moved to St. Helens. St. Helens was founded in 1848 and took its name from the nearby Mt. St. Helens. The present courthouse was built in 1906, and an annex was constructed in 1968. Most county offices are now housed in the annex.

Columbia County had a county court form of government until 1971 when a board of commissioners was elected. The 2009 population of 48,410 represented a 11.1% increase over 2000.

The primary industries of Columbia County are timber, fishing, water transportation, dairying, horticulture, and recreation. The extensive stands of old growth timber, which had attracted many of the early settlers to the area, were completely logged over by the 1950s. Second growth timber provides the raw material for local lumber and paper mills. The Trojan Nuclear Plant, located near Rainier, was in operation from 1975 to 1993.
