Lewis and Clark Interpretive Center
You arrive at the Lewis and Clark Interpretive Center perched on a two-hundred-foot cliff above the mouth of the Columbia River. Step inside and your eyes adjust to a space that traces the entire arc of the Corps of Discovery — from their departure in St. Louis all the way to this exact coastline, where the continent runs out and the Pacific begins. The exhibits are hands-on and layered, giving you as much or as little depth as you want to spend time with.
The building's position is doing a lot of work even before you look at a single display. Out the west-facing windows, the Columbia River Bar stretches below — one of the most navigated and most dangerous river mouths on the Pacific Coast. The corps reached this vicinity in November 1805 after more than eighteen months of travel, and what greeted them was weeks of brutal storms that pinned the party in place. The interpretive panels here don't gloss over that part of the story.
When you're ready to stretch your legs, interpretive trails extend directly from the center. The North Head Lighthouse sits nearby and is open to visitors from May through September. The short, paved path out to Bell's Overlook — the first piece of this park ever placed under public protection — passes old gun batteries and a boardwalk above the Pacific, and it runs about a quarter mile one way.
Note that this parking lot does not accommodate RVs, so if you arrived in a larger rig, the trailheads off the main campground road will serve you better. When you're done here, the park's twelve miles of additional trails fan out in several directions.
