Best Hikes in Kauai for Every Skill Level
Whatever kind of hike you're looking for, whether it’s something difficult with great views or a shorter walk that still displays the island's beauty, Kauai has something to suit every adventurer.
Waimea Canyon Trail to Waipoʻo Falls
Known as the 'Grand Canyon of the Pacific', Waimea Canyon is one of the most well-known places on Kauai. On this trail, you get broad views of the colored canyon walls, the green vegetation, and an excellent vantage point of Waipoʻo Falls. You will pass through a tropical forest and witness some of the island's finest scenery. Since the trail is moderately difficult, it is a suitable option if you are looking for a worthwhile hike that doesn't take all day.

Kalalau Trail
The Kalalau Trail is regarded by many as one of the finest coastal hikes, following the Nā Pali Coast and offering spectacular sea cliffs, secluded beaches, valleys, and wonderful ocean views. Careful planning is required for the entire trail, although many visitors walk only the first section to Hanakāpīʻai Beach as a memorable day trip. Hiking this trail lets you witness Kauai's wild beauty, and it is a must for serious hikers. Because conditions along the trail can change quickly, hikers should check the park notices site before their visit for the latest information on closures, access restrictions, and trail updates.

The Best Waterfall Hikes in Kauai
Because Kauai has a tropical climate, waterfalls can be found all over the island, and some of the finest hikes take you directly to these lovely places, offering a unique way to see the island's green interior.
Hanakāpīʻai Falls
Hanakāpīʻai Falls is one of the popular hiking destinations on Kauai, offering coastal views, dense jungle scenery, and a lovely waterfall at the end. The path begins on the Kalalau Trail and goes inland through a green valley until it reaches the falls. Considered one of the more challenging day hikes on Kauai, the trail features multiple stream crossings, muddy terrain, and changing weather conditions that can make footing slippery, especially after rainfall. Hikers who come prepared for the rugged conditions will be rewarded with a breathtaking 300-foot waterfall surrounded by thick tropical vegetation.
- Length: 8 miles round-trip
- Elevation: Approximately 800 feet
- Location: Hāʻena State Park
- Paved or Unpaved: Unpaved

Secret Falls (Uluwehi Falls)
Secret Falls is a unique adventure that combines hiking and kayaking: to reach the trail, you first paddle down the Wailua River, then hike through the rainforest to a beautiful waterfall. On this trip, you get to see another side of Kauai and enjoy two popular activities in a single outing. The waterfall plunges 120 feet and is set in a jungle, so the journey is worth making, particularly if you want to see more than just the beaches of Kauai.
- Length: Approximately 2 miles hiking round-trip plus 4 miles kayaking
- Elevation: About 465 feet
- Location: Wailua River Basin
- Paved or Unpaved: Unpaved
