Two Kaʻanapali Beach hotels sharing the same stretch of sand
Beach: Kaʻanapali Beach (Black Rock)
The Sheraton sits at the famous Black Rock (Pu'u Keka'a) on the northern end of Ka'anapali Beach. This section benefits from good ocean flushing around the rock promontory, and is slightly further from the stream outlets that affect southern Ka'anapali.
Beach: Kaʻanapali Beach (south end)
The Hyatt sits at the southern end of Ka'anapali Beach, closer to stream outlets (Honokowai, Wahikuli) that can affect water quality after rain. On dry days, conditions are similar to the rest of Ka'anapali.
Both hotels share Ka'anapali Beach with a moderate bacteria risk (2/5), but the Sheraton has a slight edge. Its location at Black Rock, at the northern end of the beach, benefits from better ocean flushing around the rocky promontory and greater distance from the stream outlets (Honokowai and Wahikuli) that affect the southern end where the Hyatt sits. After rain, the southern end of Ka'anapali typically sees elevated bacteria before the northern end. On dry days, the difference is negligible.
Water quality risk ratings are based on publicly available data from the Hawaii Department of Health Clean Water Branch, EPA impaired waters database, USGS stream monitoring data, and geographic analysis of pollution sources (streams, cesspools, storm drains).
