Honolua Bay

Honolua Bay is a peaceful bay with beautiful snorkeling. They bay has a ban on fishing, so you can enjoy your time there without having to trip over fishing lines or see people fishing. This also means that there is a great number of many different kinds of fish in the bay to see. Around the dropoff of the reef, one can sometimes see dolphins, manta ray, etc. Turtles are almost guaranteed, and even an octopus has been spotted.
The bay has a parking lot with free parking and a portapotty, but there is no lifeguard on duty. Mango trees and other fruit trees surround the bay and make for great snacking opportunities.
