Updated May 11, 2026

If you've ever tried planning hiking in Kauai, especially for those incredible waterfalls, you know how overwhelming the options can be. It's tough to tell which routes are genuinely worth your precious time and effort, and which are just filler. We've got you. Our komoot community has mapped, walked, and reviewed countless routes here, so this guide is a curated shortlist of the ones that truly deliver, saving you the guesswork.

Kauai's interior is a tapestry of lush tropical rainforests, deep river valleys, and volcanic formations, all feeding into spectacular waterfalls. Expect dense vegetation and varying elevations, offering everything from easy strolls to more moderate paths. The terrain often includes river crossings, which can add an adventurous twist to your day.

If you only do one, we'd start with the Upper Hoʻopiʻi Falls – Lower Ho'opi'i Falls loop from Kawaihau. At 2.5 miles (4.0 km), it's a popular, easy loop that offers views of multiple cascades within a verdant setting. For something a little different, the Uluwehi Falls loop from Wailua River State Park, at 1.9 miles (3.1 km), leads through a scenic river valley and often requires a river crossing, making it a local favorite. With over 1,200 reviews and more than 13,000 hikers exploring with komoot, you're in good company. Let's get you started.

The Ho'opi'i Falls loop trail near Kawaihau offers a captivating journey through a dense Kauai rainforest, leading to two beautiful waterfalls. You'll navigate a path that winds along the Kapa'a Stream, surrounded by towering trees, vines, and ferns, creating an atmosphere reminiscent of a movie set. While the main trail is generally flat, the descents to the Upper and Lower Hoʻopiʻi Falls are steep, often muddy, and can be technically challenging, requiring careful footing.

Planning your visit to Ho'opi'i Falls involves parking along Kapahi Road in a residential area, so please be respectful of the local community. This trail is free to access, with no permits required. Be sure to wear sturdy, waterproof hiking shoes, as the terrain can be extremely muddy, especially after rain, and trekking poles can be very helpful on the slippery sections down to the falls.

Beyond its natural beauty, the Lower Hoʻopiʻi Falls holds a unique claim to fame as a filming location for the original *Jurassic Park* movie, specifically the "Amber Mine" scene. Both waterfalls offer opportunities for swimming in their pools, providing a refreshing reward after your hike. This 2.5-mile (4.0 km) easy hike with 211 feet (64 metres) of elevation gain takes about 1 hour and 6 minutes, making it a rewarding and relatively quick adventure.

The Uluwehi Falls trail, also known as Secret Falls, offers a truly immersive Kauaʻi adventure that starts with a paddle and ends with a waterfall. You'll kayak up the Wailua River, surrounded by dense rainforest, before embarking on a jungle hike. The path winds through tropical flora, over muddy terrain, and across streams, leading to the stunning 100 to 120-foot "bridal-veil" waterfall cascading into a refreshing pool. It's a unique way to experience the island's interior, combining serene river views with an adventurous trek.

Planning your visit means preparing for a two-part journey; the 1.9-mile (3.1 km) hike with 162 feet (49 metres) of elevation gain is preceded by a significant kayak trip. While the hike itself is rated easy and takes about 51 minutes, the overall experience is considered moderate due to the paddling and often muddy, slippery trail conditions. You'll likely get wet and dirty, so wear appropriate footwear and clothing. Many visitors choose guided tours for convenience, but self-guided options are also popular, typically starting from Wailua River State Park.

What makes this route particularly notable is the required river journey, as the Wailua River is Hawaiʻi's only navigable river. This combination of kayaking and hiking provides a distinct perspective on Kauaʻi's lush landscapes, offering both a peaceful paddle and an exciting jungle trek. Despite its historical name, "Secret Falls," it's a very popular destination, and swimming in the pool at the base of the falls is a highlight for many.

The Upper Hoʻopiʻi Falls – Lower Ho'opi'i Falls loop from Hoʻopiʻi Falls offers a delightful plunge into Kauaʻi's lush jungle, leading you to two distinct waterfalls. You'll hike through dense rainforest, with towering ferns and intertwined branches creating a movie-like atmosphere, often alongside the Kapaʻa Stream. The trail is rated easy, but be ready for muddy, uneven terrain with roots and rocks, especially after rain; reaching the base of the falls involves steep, slippery sections and some scrambling.

This 2.1-mile (3.4 km) hike, with a modest 177 feet (54 metres) of elevation gain, can be completed in about 56 minutes, making it a perfect short adventure. Parking is limited to street spots at the end of Kapahi Road, so plan to arrive early. No permits or fees are needed for this publicly accessible trail, but waterproof shoes with good grip are essential for navigating the slick slopes.

Beyond its natural beauty, the Lower Hoʻopiʻi Falls holds a unique appeal as a filming location for the original Jurassic Park movie, adding a touch of cinematic history to your journey. Both waterfalls offer refreshing swimming opportunities, with the upper falls featuring a narrow plunge pool and the lower falls a larger one. It's a true hidden gem among Kauai's waterfall hikes, offering a less crowded experience than some of the island's more famous trails.

Tips from the Community

October 18, 2023, Hoʻopiʻi Falls Trail

Hoʻopiʻi Falls Trail is a trail through the jungle and leads from Kapahi Road to the Hoʻopiʻi Falls. The trail, that partly follows Kapaʻa Stream, is really short and completely flat, so you don't need any experience.

Upper Hoʻopiʻi Falls are the first falls along Hoʻopiʻi Falls Trail. The water falls into a little pool, where you can go for a little swim and cool down. Please be aware, that the path to the main falls in the eastern direction is on private property and behave accordingly if you wish to continue.

Cross Bach twice on the way there, shoes that are allowed to get wet are recommended, and because of the mud on the way there are good soles

For waterfall hikes in Kauai, it's essential to pack light but be prepared. We recommend sturdy, waterproof hiking shoes, insect repellent, a rain jacket, a reusable water bottle, and snacks. Many trails involve stream crossings, so quick-drying clothing and a small towel can be useful. Don't forget your camera to capture the stunning scenery!
