Sightseeing
There are many spectacular natural attractions around Koko Head and you could easily spend an afternoon exploring these amazing sites.
Halona Blow Hole
Halona Blow Hole lies off of Kalaniana`ole Highway. Named after the Hawaiian word for "peering place," this geyser is a natural and unpredictable wonder. When breaking surf inside the Kaiwi Channel is forced through an L-shaped lava tube, it produces a tremendous pressure that periodically creates a spectacular explosion of water. Do not get near the blowhole itself – there are barriers set up to prevent this but some people are persistent. The barriers were reinforced after a young man went beyond the barriers and looked down into the blowhole, which immediately blew up and threw the young man into the air and then down the chute. They found his body in the ocean.

Beaches
Sandy Beach Park
Sandy Beach Park, 8800 Kalaniana`ole Highway. When the waves are calm, this is a dreamy swim spot. When the waves are big, this is a very dangerous park! When the surf's up, the beach has a treacherous shorebreak and strong rip currents. If swimming doesn't look good, combing the beach for shells is always fun. Experienced shorebreak bodysurfers make this sport look fun and easy, but remember – they are experienced. Sandy Beach is as famous for its beautiful sandy shoreline as it is for the number of broken necks, backs and other injuries that frequently occur here. Talk to a lifeguard if you have any questions. The beach park has picnic areas, phones, showers and restrooms.
Makapu`u Beach Park
Makapu`u Beach Park, 41-095 Kalaniana`ole, translates in Hawaiian to "Bulging Eyes." The beach is below Makapu`u Point, considered to be Hawaii's easternmost tip. From the beach, you can see Manana (Rabbit) Island, which is a popular scuba destination since the water is shallow. This picturesque beach can be a little iffy for swimming but is popular for bodysurfing. It's just a great place to hang out – there are picnic areas, barbecue grills, restrooms, showers, phones and lifeguards.
