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 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 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
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.
