Going out to Hana to do things is the opposite to what you should be planning. You should plan to do nothing when you go to Hana and just fill in some time checking out some of the local attractions.
During the Day
Hana Cultural Center and Museum
Red Sand Beach
Waianapanapa State Park
There is not too much happening after sundown in Hana. This is a sleepy little Hawaiian village as remote as you can get on Maui. There is some live music at the Hana Ranch restaurant or at the Hana Hotel on most nights. Other than those two places, unless you know some locals who are throwing a party, that’s about it.
