The ruins of King Kamehameha's seaside home were excavated by the Bishop Museum and now are a popular destination for Lana'i tourists. Although they can usually only be reached by a 4x4, they're one of the top daytrips for families. Sights of interest include Halalu Heiau, a sacred site and ancient refuge, and Lanai's highest sea cliffs, which top out at over 1,000 feet. Brave warriors used to dive off 83-foot Kahekili's Leap. Shockingly, the energy drink Red Bull recently sponsored a cliff diving contest at this very spot, perhaps re-introducing the sport to adrenaline junkies of the world.
