Rainbow Kayaks

The five-hour Secret Falls tour covers roughly four relaxed miles. You glide past ancient heiau sites and under low-hanging hau branches while the guide explains how Hawaiians once used the river as a highway to inland taro fields. After about an hour of gentle paddling you beach the boats on a sandy bank, trade PFDs for daypacks and follow a shaded trail that crosses several ankle-deep streams. Forty minutes later the forest opens on 120-foot Uluwehi Falls—better known as Secret Falls—where you cool off in the mist and refuel on deli wraps, tropical fruit and iced water pulled from the guide's soft cooler.

Back at the river you swap seats so each paddler gets bow time, and the outgoing current makes the return drift even easier than the trip in. First-time kayakers stay comfortable thanks to molded backrests and wide, flat hulls that shrug off passing photo boats. Life vests, dry bags, walking sticks and reef-safe sunscreen are all part of the package, and group size tops out at twelve guests, leaving plenty of space for tripod shots without competing paddle blades.

If you prefer exploring on your own schedule, Rainbow Kayaks also offers full-day rentals with laminated river maps, tide-timing tips and complimentary roof pads for easy transport to Hanalei or Huleia. Staff check wind forecasts every morning and suggest the best launch windows, so you spend more time on smooth water and less time battling afternoon trades.

Age, weight and footwear rules keep the tour safe—kids must be at least five, and closed-toe water shoes are required for the trail. Free parking and clean restrooms sit steps from check-in, and a freshwater hose rinses salt and mud before you head for a post-paddle shave ice in Kapa'a.
