The waterfall announces itself first through sound—you'll hear it from the parking area, a constant rush that grows louder as you walk down the path. When the beach opens before you, the first thing you notice is the stream, maybe three meters wide, flowing across the sand in a channel it's carved over centuries. During the wet season it runs tea-colored from tannins leached from jungle leaves; by March it turns nearly clear, cold enough to make you gasp when you step in.

You can follow the stream inland about fifty meters to where it drops over a limestone ledge in a white curtain, collecting in a pool deep enough to stand chest-high. Local families gather here in the late afternoon, children shrieking as they jump from the rocks while parents wash off the day's salt in the fresh water. The pool stays shaded until early afternoon, ferns and wild ginger crowding the banks, and you'll feel the temperature drop several degrees when you step under the falls.
Back on the beach, the sand spreads north and south from the stream mouth, coarser and darker than nearby beaches due to the sediment the waterfall carries down. At low tide, you can wade across the channel to explore the tide pools on the south side, where small crabs scatter at your approach. The mixing zone where stream meets sea creates confused currents—swimming here requires attention to the changing patterns, especially during incoming tides when the ocean tries to push back against the freshwater flow.
