Narada Falls Trail from Paradise is an out-and-back walk from the Henry M. Jackson Memorial Visitor Center to the lower viewpoint beneath Narada Falls. Plan for about 3.1 miles round trip and roughly 2.5 hours, with extra time if you want to stay at the falls. The route drops about 1,000 feet on the way down, so the return is a sustained climb. This is the longer Paradise walk, not the short roadside path: from the Narada Falls rest area, the separate lower-viewpoint spur is about 0.4 miles round trip.
The map labels individual junction distances but does not give this hike a single total; those labels suggest roughly 2.8 miles round trip. Following the connected walking line from the visitor center to the lower viewpoint measures about 1.56 miles one way, including the access connections at either end. The stored distance uses that mapped line, rounded to 3.1 miles round trip, as the more useful planning estimate.
