Spouting Horn Park has a few cool attractions right nearby. The first one is the Spouting Horn, which is a natural rock feature that creates a gyser-like effect and shoots water up into the air when waves come in and crash on the rocks. There is also McBryde Garden on the north side of Lawai Road, with self-guided tours or the option of getting a tour guide. There are public restrooms at Spoouting Horn Park, and it's a great place to spend the afternoon.

The Tree Tunnel was made by 500 trees in 1911 as a gift to the community from Pineapple Baron Walter McBryde. They were extra trees from the project of his estate mansion, which is the location of Kukuiolono Park and Golf Course. He helped found the McBryde Sugar Company and was the manager of the Kaua`i Pineapple Company. This is part of the Holo Holo Koloa Scenic Byway.

The Spouting Horn is a blowhole on Kauai's stunning South Shore that creates a spectacular scene as waves funnel into lava tubes, erupting up to 50 feet high with a roar. This picturesque natural wonder comes alive with the hiss and spray that inspired a fascinating Hawaiian legend.

The Wailua Complex on Kauai island was once the epicenter of political, social, and spiritual life for ancient Hawaiian royalty. Wailua served as one of two main hubs where Kauai's paramount chief lived and ruled for much of the year. The area contains a wealth of significant archaeological sites that provide a window into its esteemed past. The Wailua Complex of Heiaus consists of several important structures including the Hikinaakala, Holoholoku, Malae, and Poliahu heiaus (ancient Hawaiian places of worship), the Hauola puʻuhonua (a refuge site), ancient Hawaiian petroglyphs etched into stone, a rock believed to be a royal birthstone, and a bellstone .

It's impressive what nature creates. The water is shot up by the surf through a hole in the rock.
