Overview
This five-hour outing from Kapaʻa pairs a kayak paddle up the Wailua River with a hike to Uluwehi Falls, the waterfall everyone calls Secret Falls. Duke's Kayak Adventures runs it: you check in at their shop off Kuhio Highway, get a backpack style dry bag for your gear, and paddle with a professional guide toward the trailhead inside Wailua River State Park. The waterfall stop itself runs about 30 minutes before the return paddle.
The hike is a different story. That combination suits reasonably fit visitors aged 13 to 69 who want an active half day rather than a scenic float. Groups are capped at 12. Guides get consistent praise for safety, local history and plant life commentary.
The falls area gets busier as the day goes on, according to one reviewer, while another found the late-day stop uncrowded. You need to arrange your own transport, bring your own water and lunch, and pay Hawaii State fees on site.

What To Expect From The Tour
A few practical points shape whether this tour is a good fit and how much you enjoy it.
- Footwear matters. Secure shoes are mandatory, no flip flops. Reviewers repeatedly stress water shoes with traction for the muddy trail and river crossings, and several note shoes get thoroughly wet and dirty regardless.
- Bring your own supplies. Drinking water, lunch and snacks are not included, and the listing says to bring plenty of water. Swimsuit, hat, sunscreen, mosquito repellent and a towel are all recommended. A backpack style dry bag is provided, and the listing suggests Ziploc bags for phones and cameras that are not waterproof.
- Moderate fitness needed. The listing requires the ability to hike approximately two miles through rocky, muddy and slippery terrain, and it rules out recent back, knee or ankle injuries.
- Go early if you can. One reviewer found the falls busier as the day goes on and recommended a morning start, while another found the late-day stop uncrowded. Timing is worth thinking about when you book.
- Weather cuts both ways. Rain makes the trail muddier and the river higher, and the tour runs in wet conditions. Reviewers still enjoyed rainy-day trips, and the operator cancels or rebooks if weather makes the tour unworkable.
- Group size. The tour has a maximum of 12 travellers. Reviewers mention guides pacing the day well and offering to take photos.
Common issues. There is no hotel pickup or drop-off, no lunch and no drinking water included, and you pay Hawaii State fees on site of $5 per person plus $10 per car. The listing recommends mosquito repellent for the hike. Weather and a minimum number of travellers can cancel a departure, though in both cases you are offered a different date or a full refund, and anything cancelled inside 24 hours of start time is non-refundable. The tour is not wheelchair accessible and is not suitable for those with heart problems or recent joint injuries.
