Storms River Mouth is the headline sight in the Tsitsikamma section of Garden Route National Park. A short boardwalk trail drops through forest to the coast, where suspension bridges cross the dark river just before it meets the Indian Ocean. The setting is compact but dramatic: cliffs, surf, fynbos, and forest all visible in one walk.
It is an easy outing by Garden Route standards, though the steps can still feel longer on a hot day. Go early if you want the bridge and viewpoints before the tour groups arrive.
