The trail climbs the rock through 52 switchbacks. Handrails, bridges and boardwalk sections carry you around the steepest parts; you are walking a built route, not scrambling up bare rock. The turns give you places to catch your breath, and the view changes as you rise above the shoreline. The Columbia opens in both directions from the ascent, so do not save every look for the top. Some bends show more of the gorge than the wooded summit. At the top, the view opens upriver toward Bonneville Dam.
The path is narrow in places, with the river far below the rock face. The rails make the route feel secure, but this is still an exposed climb, and people coming the other way share the same walkway. Take your time on the tight turns and pause where the route widens instead of trying to pass in a hurry. If heights make you uncomfortable, the boardwalk sections may feel more demanding than the mileage suggests.
