The counterpart to Hilo is Kailua-Kona, the secret capital of the Big Island. The notable difference is that everything is considerably more modern in Kailua-Kona than in the small sleepy town of Hilo. Hotels, shops and restaurants can be found on Alii Drive. The reconstructed Ahuéna Heiau (a temple of King Kamehameha I.), Hulihe'e Palace and Moku´aiku Church, built of blocks of lava and one of the oldest mission churches on Hawaii are all worth seeing. Kailua-Kona is also world-famous for the spectacle held each October - the Ironman Triathlon.
