The best thing to do in Hana is just be. The world will take care of the action if you allow it to. We stayed at an inn with around 10 rooms and suites, but felt like we were alone. Each day in Hana must begin with a breakfast consisting of pineapple juice and guava juice, along with whatever fresh fruit is available. You will not get tired of eating pineapple. We quickly developed a taste for coconut candy, sold at roadside stands, as a mid-morning treat. It looks like wood chips but tastes like heaven.
When you are in Hana and are looking for something to do, get in your car and drive. Stop anywhere that looks interesting. There are dozens of waterfalls, and the hikes of varying distances are exhilarating. The birds and flowers seem to have escaped Eden. There is no one place you have to see, though the National Park at O'heo Gulch would be that place if there were one. Blue Pool provided us with the waterfall picture that makes everyone most jealous. You should, and will, discover your own favorites in addition to these obvious examples of why Hana, the road to Hana (and past it), and the rainy side of the island constitute the reason to go to Maui. And to return.
Quick Tips:
It will rain. Get over it. There will also be some sunshine, but not enough to burn. Rent a convertible, put the top down when you can--for the smells if nothing else--and don't get in a hurry. Pull over and let faster drivers pass.
There is one great meal on this side of the island after you pass Paia (if you are a Willie Nelson fan, stop at Charley's there). It is at the Hotel Hana Maui, and it’s fantastic. Eat there every night if you can afford the to per person average. Also, make time to go to Mama's at the beginning of the Road to Hana. Otherwise, picnic a lot.
Bring your own snorkel gear--you may want to pull over and dive in sometimes, as we did--and some tabbies for your feet. And sneakers you can leave in the garbage before packing to go home.
Vitally important tip! Buy the Ultimate Guide to Maui--it's a Blue Trade paperback. This is all you need to find more than you imagined when seeing the sites. But don't rely on their restaurant picks.
Best Way To Get Around:
Rent that convertible and carry good shoes for hiking over wet terrain. The best waterfalls must be hiked to. The best red-sand beach is a short but dicey walk along a cliff. You are going to want to see what's around the next corner, whether you are driving or walking.
