Fort Cascades National Historic Site

Pacific Northwest history along a beautiful wooded trail.

The Fort Cascades Historic Site is located one mile downstream (west) of the Bonneville Dam, and is reached from the Dam Access Road on Hamilton Island, off of Washington State Highway 14.

Fort Cascades was an army fort built in 1855 to protect a portage road around the lower cascades rapids of the Columbia River.  The fort burned down in 1856 and the area was abandoned in 1861 and then flooded out in 1894. Pick up a brochure at the kiosk at the trail head so you can follow the interpretive markers along the trail.

The 1.5 mile Fort Cascades Trail will take you past historic sites (don’t expect to see remains of buildings), beautiful mossy rocks and woods, and eventually leads into the town of North Bonneville if you do not follow the trail looping back. It is a lovely flat trail to take on a warm day because of the shade.
