Economy Kailua-Kona saw an economic downturn during the 2008 national financial crisis but in the early 2010s has seen significant growth and economic development. Tourism also saw a downturn in the late 2000s but has since seen some resurgence. Visitor air arrivals alone increased about 160% from 2010 to 2017. The University of Hawaii held its first classes at the new Hawaii Community College Palamanui Campus in 2015. Since the early 2000s the Kona side had seen significant amounts of vog from Puʻu ʻŌʻō and Kīlauea, but that changed in May 2018 when Kilauea largely ceased its emissions. The air in Kailua-Kona is clearer than it has been in decades. Attractions and events Kailua-Kona is the host of the annual Ironman World Championship triathlon, the annual Kona Coffee Festival, and the Hawaiian International Billfish Tournament. Kona coffee is the variety of Coffea arabica cultivated on the slopes of Hualālai and Mauna Loa in the North and South Kona Districts. The Kona Historical Society manages two coffee related historical sites: the Kona Coffee Living History Farm and the H.N. Greenwell Store Museum just south of Kailua-Kona. Ali'i Drive, Kailua's oceanfront downtown street, starts at Kailua-Kona Pier. It has also been given the designation as a Hawaii Scenic Byway called the "Royal Footsteps Along the Kona Coast". This byway features archaeological sites that have survived for hundreds of years. North of the pier is the Kamakahonu royal residence and Ahuena Heiau, and nearby now stands the King Kamehameha's Kona Beach Hotel. Another royal residence is Hulihee Palace, used by members of the Hawaiian royal family until 1914. The Historic Kona Inn and other shops are on the street. Churches on the drive include Mokuaikaua Church, Hawaii's first Christian church built in 1820, Saint Michael the Archangel Catholic Church, and Living Stones Church, a historical structure built after Mokuaikaua and used as a Christian Missionary landing location in the 1800-1900. Parks include La'aloa Bay (also known as Magic Sands or White Sands Beach) and Kahaluu Bay, which is a popular snorkeling location. Boat tours which allow tourists to
