Honolua, Hawaii

Honolua Bay, West Maui A rocky, reef-lined bay inside the Honolua-Mokulēʻia Marine Life Conservation District, where taking or harming any marine life is banned and the fish show the benefit. This is a summer snorkel: large winter surf often makes the bay dangerous, and the state recommends entering only in calm seas. No lifeguards are stationed here and the entry is over rocks rather than sand, so bring water shoes and save it for a flat morning.
