Lace up your boots, pack your water bottle, and get ready to explore some of the most breathtaking scenery on Earth. We’ll guide you through some of Hawaii’s most scenic trails, giving you all the details you need to plan your adventure.

Kauai: The Garden Isle’s Emerald Trails

Known as the “Garden Isle,” Kauai is a haven of lush vegetation and dramatic cliffs. Its trails offer a diverse range of experiences, from challenging coastal hikes to gentle walks through rainforests.

Kalalau Trail (Na Pali Coast)

Perhaps Kauai’s most famous hike, the Kalalau Trail, is not for the faint of heart. This strenuous 11-mile (one-way) trail winds along the stunning Na Pali Coast, offering panoramic views that will leave you breathless. Be prepared for steep climbs, narrow ledges, and stream crossings. Permits are required for day hikes beyond Hanakapi’ai Valley and overnight camping. The trail’s difficulty is compounded by its exposure to the elements. Sunscreen, plenty of water (at least 3 liters per person per day), and sturdy hiking boots are essential.

Permits and Reservations: Obtaining a permit is crucial. You can book permits through the Hawaii Department of Land and Natural Resources (DLNR) website. Permits can sell out months in advance, especially during peak season (summer months). Early booking is highly recommended.

Getting There: The trailhead is located at Ke’e Beach, at the end of Highway 560 on Kauai’s north shore. Parking is limited, so arrive early, especially if you’re hiking during the day. A shuttle service is also available from various locations on the island. Check the Go Hawaii website for transportation options.

Tips: Consider breaking the hike into smaller segments. Hiking to Hanakapi’ai Falls (a 4-mile round trip) is a popular option for a day hike, offering a taste of the Kalalau Trail without requiring an overnight commitment. Always check the weather forecast before you go, as the trail can become treacherous in wet conditions. Remember to pack out everything you pack in to help preserve this pristine environment.

Awa’awapuhi Trail

This shorter (6 miles round trip) but equally rewarding trail leads to the Awa’awapuhi overlook, offering stunning views of the Nounou Mountain range and the steep cliffs of the Na Pali Coast. The trail descends through native forest, ending abruptly at the cliff edge. Be cautious near the overlook, as there are no guardrails.

Cost: There are no entrance fees for the Awa’awapuhi Trail itself, but you may encounter parking fees in the Kokee State Park.

Directions: The Awa’awapuhi Trailhead is located within Kōkeʻe State Park. From Waimea, drive north on Highway 550 for approximately 15 miles. The trailhead is well-marked.

Recommendation: Bring a camera! You’ll want to capture the breathtaking views from the overlook. Because this trail is located at a higher elevation, be prepared for cooler temperatures and potential fog.

Sleeping Giant (Nounou Mountain East Trail)

For a more moderate hike with stunning views, the Sleeping Giant Trail is a great option. This 3.4-mile (round trip) trail climbs to the summit of Nounou Mountain, which resembles a sleeping giant from certain angles. The summit offers panoramic views of the surrounding area, including the eastern coastline and the Wailua River.

Directions: There are multiple trailheads for Sleeping Giant. The Nounou East Trail, which starts near the end of Haleili Road, is a popular choice. Use Google Maps by searching “Nounou Mountain East Trailhead” for accurate directions.
