Though this 2.2-mile trail can be a bit tricky to find, the hypnotic sounds of gushing water as a reward may make the effort worthwhile. The Hoopii Falls trail starts out on a dirt path (once a dirt road) guarded by an old metal gate covered in shrubbery.
Descend the dirt path (muddy path after rains) until you level off and a few distinct trail options appear on the left. They all go in the same direction, the Kapaa Stream, so pick one and keep an eye out for the smaller single-track trail that meanders along the stream. Once you hear the Upper Falls, keep an eye out for a route down. Use caution as this can be very slippery and note that whatever you go down, you’ll have to go back up.
If you’d like to continue to the Lower Falls, make your way back up to the single-track trail and continue in the direction of the stream. After working its way inland, the trail forks. Take the option to the left, back towards the stream.
Once you reach a T, the option to the left will lead you to the top of the falls, with no way of getting to the bottom, and the option to the right will lead uphill, past the falls, and offer another option to the left to go to the bottom of the falls.
Choose your own adventure and be safe, especially on the slippery slopes heading down to the falls. Whenever your heart’s desires (or your camera’s memory cards) are full, return the way you came.
Turn right onto Kapahi Rd. off of Kawaihau Rd., drive 0.3 miles and look for unmarked trailhead on left. Park on the side of the road.
Always tell someone where you are hiking (name and location of trail) and when you plan to return.
Bring water and stay hydrated. Do not drink from the waterfalls and streams. Kauai has been known to have seriously harmful bacteria in its fresh water.
Bring snacks as its always a good idea to provide your body enough calories to support the physical activity you are engages in.
Its important to know that cuts in tropical climates should be closely monitored. Do not expose open wounds or cuts to the river.
Comfortable footwear with good tread that can stay strapped to your feet is a must. Wear shoes that you don’t mind getting stained with the Kauai red dirt.
Dress in layers so you can easily remove a layer when you get hot. And add one back on when it cools of again. Because we are close to the equator the trails heat up quickly. However, conditions cool just as fast; winds picking up speed and a passing showers causes wind chill factor.
