Hawaii may be best known for its stunning beaches, but the islands also offer some incredible whitewater and kayaking experiences for outdoor enthusiasts. One popular destination is the Wailua River on Kauai, which offers a beautiful and serene paddle through lush rainforest with the option for more adventurous whitewater sections further upstream. The river is best experienced at moderate flow levels, around 200-400 cubic feet per second, to ensure a fun and safe trip.

For those seeking more adrenaline-pumping rapids, the Hanauma Bay on Oahu is a must-visit spot. With Class III-IV rapids, this river offers a thrilling ride through narrow canyons and breathtaking scenery. It is recommended to go with a guide or experienced kayaker due to the technical nature of the rapids. No matter which river you choose to explore in Hawaii, it is important to always check current streamflow levels, wear appropriate safety gear, and be mindful of the local weather conditions. With the right preparation and a sense of adventure, a whitewater or kayaking trip in Hawaii is sure to be an unforgettable experience.
