One great photo opportunity at the Keanae Arboretum is the easily accessible rainbow eucalyptus trees.  They are located just steps off the trail, and their iridescent bark is unforgettable.  Also found in Keanae Arboretum are Hawaiian ti plants, which were revered by ancient Hawaiians as sacred, and believed to be endowed with protective spiritual powers or mana.  Only high priests and chiefs were allowed to wear ti leaves during ritual ceremonies.Hana Picnic Co has more information and directions!
