Just a few miles west of Hanalei Bay, at its western tip, is Lumahai Beach. Parking is in a dirt lot, and there are no facilities. The sand near the water is usually steep because of persistently strong surf. This creates extremely dangerous shore-break conditions.
Swimming at Lumahai Beach is not recommended unless you are very experienced. It is not favorable for snorkeling as the under-water environment is all sand. It is, however, great spot for experienced surfers and body-boarders during the winter months. Lumahai Beach deserves a visit because of its wide, white sandy beach, and its delightful scenery. With some rocky outcroppings to the east, it gushes with heavenly views when waves created by the beauty, and power, of Mother Nature come crashing in.
On the west end, Lumahai stream flows into the ocean, making it an alluring spot for frolicking in cool, fresh water. Remember that you are not the only one who enjoys frolicking in these streams, so do not drink the water as it may be contaminated with leptospirosis.
