More ways to explore the area's outdoor wonders
A low, green canyon opens as you push from the sand: a calm river threads inland beneath ferns and towering ʻōhiʻa, the water reflecting ridgelines that rise like folded pages. Paddle quietly and the valley answers — insect chatter, a distant surf, and the occasional call of a seabird as the channel nudges you toward wide, turquoise Kahana Bay.

Bring a 4-door vehicle or plan transport
You’ll need a car to move the kayak to Kahana Bay (storefront in Kailua provides foam pads and straps); measure cargo space beforehand.
Use reef-safe sunscreen
The bay and coral habitats are sensitive — mineral-based sunscreen protects both you and the reef.
Pack a drybag and secure valuables
A small drybag keeps phone, keys, and a light layer dry during river-to-bay paddling and potential splashes.
Watch the bay entrance for wind-driven currents
Currents can shift where the river meets the ocean; wait for calmer conditions or stick near the shoreline if unsure.
Swimsuit and quick-dry layers
Comfortable, fast-drying clothing keeps you mobile and comfortable during warm days on the water.
