The trail goes down to the beach and runs north along the shore through the beach dunes. There are several access points, parking areas and public restrooms along the trail through Seaview and Long Beach. Management is shared between State Parks and the cities of Ilwaco and Long Beach. One section in Cape Disappointment State Park between the Overlook and Beard Hollow is very steep and therefore has not been paved. Most of the trail is ADA accessible. Visitors can learn about the expedition of the Lewis and Clark Corps of Discovery at the park's Lewis and Clark Interpretive Center. Alternately, take the North fork along the beach, through Seaview and Long Beach, at one point paralleling the city's extensive wooden boardwalk from Bolstad Ave.to Sid Snyder Drive, and terminating at a bronze sculpture: Clark's Tree, a sculpture in memory of Clark’s northernmost trek on the beach.

The trail is located on SW Washington’s 28 mile Long Beach Peninsula recreation destination. Bound by the Pacific Ocean to the west, the Columbia River to the south, and Willapa Bay to the east, the Lewis and Clark Discovery Trail crosses several distinct ecosystems and is adjacent to Cape Disappointment State Park, the Willapa National Wildlife Refuge, and the longest continuous truss bridge in North America; the breathtaking Astoria Megler Bridge spanning the 4.1 mile mouth of the Columbia River between Washington and Oregon.
The Lewis and Clark Discovery Trail is one of the most scenic in the Pacific Northwest with outstanding views of the ocean, grassy dunes, transitional wetlands and forest groves. The trail also offers a collection of impressive public art and artifacts from the Lewis and Clark Expedition that add to the trail's natural beauty.
