At mile marker 24, just as you approach the bridge, look toward the mountains to catch a glimpse of Hanawi Falls. This lush spring-fed stream travels 9 miles to the ocean, and the waterfalls are real crowd-pleasers, even when rains have been light. The best views are from the bridge. It is not safe to hike to the falls, and you must cross private property to get there. We strongly advise against this.
At this arboretum you can enjoy tropical trees in their natural setting or enjoy a challenging hike into the forest. Signs help you learn the names of the many plants and trees now considered native to Hawaii; the rainbow eucalyptus trees are a big draw here (do not write on them). The meandering Piinaau Stream adds a graceful touch to the arboretum and provides a swimming pond when there is enough water. You can take a fairly rigorous hike from the arboretum if you can find the trail at one side of the large taro patch. Be careful not to lose the trail once you're on it. A lovely forest waits at the end of the 25-minute hike.
In one direction from this observation point near mile marker 17, you can take in the patchwork effect the taro patches create against the dramatic backdrop of the ocean. In the other direction, there are awesome views of Haleakala through the foliage. This is a great spot for photos, but it is not recommended that you fly your drones over the inhabited areas.
For a leg-stretching break (and restrooms) stop at this small roadside park just past mile marker 22. Here you can enjoy the short hike to a small waterfall and pool across the highway from the bathrooms. The park is one of the few places on the highway with a decent amount of parking. It also has picnic tables and friendly cats to welcome you.
Past mile marker 18, enjoy some time at the concrete arches of the beautiful Waikani Stream Bridge before heading to the parking lot of this overlook near mile marker 20. From this perch, you can see Wailua Canyon in one direction and, in the other, Wailua Village, where 94% of the residents have at least partial Hawaiian blood. As you look down, note the village's landmark 1860 church, which was allegedly constructed of coral that washed ashore during a storm. Wailua asks that you respect the privacy of its residents by not entering the village. Note, too, that although you'll want to take photos of the scenery from the overlook, doing so using a drone flown over the populated area is strongly discouraged.
