Lahaina, Maui — ranked by water quality and bacteria risk
Lahaina is the historic former capital of the Hawaiian Kingdom, sitting on Maui's sun-drenched west coast. The town was devastated by wildfires in August 2023, and recovery and rebuilding continue as of 2026. The adjacent coastline stretching north toward Kaʻanapali and Kapalua holds some of Maui's best-known resort beaches. West Maui's leeward position means less rainfall than the island's north or east shores, which translates to generally clearer ocean water and fewer brown water advisories. From Lahaina, a string of beaches runs north along the Honoapiilani Highway, each offering different conditions from gentle resort sand to world-class snorkeling coves.
Lahaina sits on the Honoapiʻilani Highway (Route 30), which runs along Maui's west coast from Māʻalaea to Kapalua. All beaches listed are north of town along this same highway.
