NTBG’s Allerton Garden Garden is located on the south shore of Kauai in the picturesque Lawai Valley. Tours run daily and include a ride from the Visitors Center in Poipu along a scenic coastal route and continue along the valley rim on a former sugarcane train railbed. Visitors disembark on the valley floor to explore this former private estate, named by National Geographic Traveler magazine as one of the 50 places to see in a lifetime. Plants form the walls of outdoor rooms, the canopy of trees the ceiling. Housed within are elegant statuary and water features. A popular spot for photos is the ‘Jurassic trees’, with their massive curving roots.National Tropical Botanical Garden is a nonprofit institution, dedicated to saving and studying tropical plants.
