What to Know Before Hiking to Kauai Waterfalls
- Check the weather: Heavy rains can cause flash flooding and make trails dangerously slippery.
- Wear the right gear: Sturdy hiking shoes with good grip, a rain jacket, and insect repellent are must-haves.

- Respect nature & culture: Stay on marked trails, don’t disturb plants, and avoid swimming where posted.
6 Best Waterfall Hikes in Kauai
1. Hanakapiai Falls Trail (Na Pali Coast)
- Distance & Difficulty: 8 miles round trip; challenging
- Why Go: One of the most famous Hawaii waterfall trails, Hanakapiai Falls cascades approximately 300 ft (≈91 m) at the visible section, though the full vertical drop may be considerably higher—potentially exceeding 400 ft according to some topographic estimates.
2. Wailua Falls Trail (East Side)
- Distance & Difficulty: Short, unofficial trail from the lookout; slippery
- Why Go: Featured in Fantasy Island, this 84-foot waterfall is easily admired from above, but adventurous hikers can take the short, steep trail for a closer look.
3. Ho’opi’i Falls Trail (Kapa’a)
- Distance & Difficulty: 2 miles round trip; moderate
- Why Go: A local favorite, Ho’opi’i Falls features two cascades, lush jungle scenery, and peaceful swimming holes (when safe).
4. Opaeka’a Falls (Wailua)
- Distance & Difficulty: Short hike to lookout; there is no official trail to the base or top of ʻOpaekaʻa Falls. Viewers must admire it from a roadside overlook; venturing beyond marked boundaries is illegal and potentially dangerous.
- Why Go: This 151-foot waterfall is one of the most photographed in Kauai. While most enjoy it from the paved lookout, small side trails may lead to better vantage points.
5. Secret Falls (Uluwehi Falls)
- Distance & Difficulty: 2-mile kayak + 1-mile hike; moderate
- Why Go: A true Kauai hidden waterfall, this 100-foot beauty requires paddling the Wailua River, followed by a jungle hike. The secluded setting makes the effort worthwhile.
6. Kalihiwai Falls Trail (North Shore)
- Distance & Difficulty: Short hike; easy
- Why Go: Accessible via guided tours on private land, Kalihiwai’s multi-tiered falls are perfect for photography and peaceful exploration.

- Join a guided hike for access to private land and local-only spots.
- Look for trails along rivers and valleys—these often lead to lesser-known falls.
- Always prioritize safety over exploration; many “unmarked” trails can be hazardous.
