5 Best Sights in Maui, Hawaii

Just beyond mile marker 10, the Garden of Eden Arboretum offers interpretive trails through 26 manicured acres. Anyone with a green thumb will appreciate the care and attention given to the more than 500 varieties of tropical plants—many of them native. Trails also lead to views of the lovely Puohokamoa Falls and provide a glimpse into the botanical wonders that thrive in this lush region. Be sure to stop by the gift shop on the way out to shop for items made by local artisans and to hang out with the ducks and peacocks. Avoid lines and crowds by visiting when the garden first opens (around 8 am) or after 2 pm (closing time isn't until 4).

Part of the National Tropical Botanical Garden network, Kahanu Garden features a variety of plants as well as cultural and archaeological sites. Standout features include a native plant garden, thatched-roof canoe hale, beautiful ocean views, and Piilanihale Heiau, the largest heiau (temple) in Polynesia. Two-hour guided tours are offered Wednesday through Friday mornings, but 1½-hour self-guided tours are an option, too.

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.

This picturesque garden has assimilated itself naturally into its precipitous 8-acre habitat. More than 2,500 plants and trees fill the enchanted garden, including native koa (prized by woodworkers) and kukui (the state tree, a symbol of enlightenment). A flowing stream feeds into a koi pond, where nene and ducks meander, and a paved, stroller- and wheelchair-friendly pathway winds through the grounds. The carved tiki exhibit, aviary, and Jackson chameleon exhibit entertain the keiki (children).

Hawaiian and Polynesian species are cultivated at this fascinating 7-acre garden, including Hawaiian bananas; local varieties of sweet potatoes and sugarcane; and native poppies, hibiscus, and anapanapa, a plant that makes a natural shampoo when rubbed between your hands. Reserve ahead for the weekly ethnobotany tours. Self-guided tour booklets and an audio tour wand are included with admission (docent tours must be arranged online in advance).
