In a nutshell: Tiny beach of mixed rock and sand. Unlikely to be worth your time.
Minuses: The muck?
Sound-bite: “What’s that smell?”
QUICK SUMMARY:
The name probably translates most closely into “the muck” which is said to refer to the stagnant stream that empties into the ocean in line with the current. I’ll let you be the judge 🙁

Tropical storm Olivia ruined 30 feet of Lower Honoapiiliani Road here, threatening water and sewer lines user the raid. Muck and what is that smell? may be worse now. Too bad, nice view here of Molokai.
