About Keahua Arboretum
Aloha! Keahua Arboretum is one of Kauai's most accessible botanical gardens, located in the lush rainforest just off Highway 56 near Lihue on the East Side. The standout feature here is the rainbow eucalyptus trees—their multicolored bark creates a striking visual that's worth the visit alone.
The arboretum showcases an incredible diversity of native Hawaiian plants alongside exotic species from around the world. You'll find easy walking trails perfect for families, plus lovely picnic areas where you can relax by babbling streams. The accessibility is excellent—no strenuous hiking required, making it ideal for visitors of all ages and abilities.
Visit in the morning when light filters beautifully through the canopy and temperatures are cooler. The garden is open daily from 7 AM to 4 PM, giving you plenty of flexibility. Parking is straightforward right at the entrance. This spot works especially well on rainy days when other outdoor activities might be canceled—the forest canopy provides natural shelter while you explore.
Bring your camera for those rainbow eucalyptus shots, pack a picnic lunch, and plan to spend a few hours walking the grounds and taking in the botanical variety.
