In Short
From Kailua-Kona's Palani Junction, Highway 180 south runs though Kona's legendary coffee country, a 20-mile corridor of volcanic soil where the world's supply of Kona coffee is produced. More than 600 farms share this scenic strip on Mauna Loa's western slopes; many farms welcome guests to stop in for a taste and a history lesson. Drive highlights include Ueshima Coffee's Roastmaster tour; Ferrari Coffee Visitor Center; Kona Mountain Cafe; and Royal Kona Museum & Coffee Mill.
