What to do in Ko Olina

Ko Olina was designed as a resort enclave on the dry, sunnier west side of Oahu. Most of what's worth doing here you can get to without a rental car. The Ko Olina Ocean Adventures catamaran is based at the marina, so you walk straight from Aulani or the Four Seasons to the dock. Hawaii Nautical's sunset sail throws in a free Ko Olina shuttle. Wet'n'Wild is five minutes inland in Kapolei. For a more upscale half-day, Wild Side Specialty Tours runs semi-private marine biologist-led trips out of Waianae and routinely encounters dolphins and (in season) humpback whales.
