Islanders once lived in harmony with the land: farming, fishing and harvesting fruit. Today the state imports 80 to 90 percent of its food. Visit Kaloko-Honokohau to catch a glimpse of the island's ancient agricultural traditions, which Hawaiians are working hard to revitalize. The park's landscape of rugged rock contains more than 200 archaeological sites, ranging from fishponds and elevated planters to petroglyphs, lava tube shelters and holua (toboggan-like slides, used only by aristocrats). Watch for native species like the fragrant pua pilo flower and the endangered Hawaiian black-necked stilt.
