Water quality status and bacteria risk rating
📍 Kona Coast, near Place of Refuge (Puʻuhonua o Hōnaunau)
Two Step at Honaunau Bay is one of the Big Island's premier snorkeling destinations with excellent water quality. The dry Kona Coast receives very little rainfall, making storm runoff extremely rare. Crystal-clear visibility of 80–100+ feet is common.
The natural lava rock entry points give the spot its name — flat ledges create a two-step staircase into the water. The bay is home to abundant coral, tropical fish, sea turtles, and occasional spinner dolphins. There are no major pollution sources nearby, and the ocean provides excellent natural flushing.
Based on: DOH monitoring, very dry Kona Coast climate, open bay with excellent flushing, no nearby runoff sources
The Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. Two Step on the dry Kona Coast rarely sees significant rain, but on the rare occasions it does, the same caution applies. Always check the water visually before entering.
