Narrow Limahuli Valley, with its fluted mountain peaks and ancient stone taro terraces, creates an unparalleled setting for this botanical garden and nature preserve. Dedicated to protecting native plants and unusual varieties of taro, it represents the principles of conservation and stewardship held by its founder, Charles "Chipper" Wichman. Limahuli's priomordial beauty and strong mana (spiritual power) eclipse the extensive botanical collection. It's one of the most gorgeous spots on Kauai and the crown jewel of the National Tropical Botanical Garden, which Wichman now heads. Call ahead to reserve a guided tour, or tour on your own. Be sure to check out the quality gift shop and revolutionary compost toilet, and be prepared to walk a somewhat steep hillside. www.ntbg.org. COST: Self-guided tour $15, guided tour $30 (reservations required). OPEN: Tues.--Sat. 9:30--4.
