As you walk on to Shipwrecks Beach in Poipu, facing the water, and turn to the left you’ll see a bluff. If you walk to the end of the beach and walk up the trail that takes you to the top of that bluff, that’s the beginning of Mahaulepu Beach Trail. It’s safe for kids, easy to hike, and relatively short. There’s an upper and lower trail but both lead to the same place. There’s also a few little coves to look for treasures. It was raining when we went so we wore ponchos. Still beautiful even on a cloudy day.
