Maha'ulepu Heritage Trail
A spectacular 4-mile round trip coastal trail along Kauai last undeveloped south shore coastline. The trail passes ancient sand dunes turned to stone (lithified dunes), dramatic sea cliffs, tide pools, blowholes, and a sinkhole with an ancient Hawaiian petroglyph cave. Kids are fascinated by the geological formations and the wild coastline. Humpback whales and monk seals are seen from the trail in winter. The trail is mostly flat but exposed to sun and wind. This is one of the most geologically interesting hikes in Hawaii.
