Hawaii’s volcanic origins and dramatic geography create some of the world’s most spectacular hiking opportunities. From emerald cliffs plunging into the Pacific to ancient crater rims and hidden waterfalls, the islands reward those willing to venture beyond the beaches.
Here are 16 hiking trails that showcase Hawaii’s most breathtaking views across all four major islands.
Diamond Head Summit Trail
The crown jewel of Oahu hiking delivers panoramic views that define the Hawaiian experience. This moderately challenging 1.6-mile round-trip trail climbs 560 feet through tunnels and up stairs to reach the iconic crater rim.
From the summit, sweeping vistas stretch from Waikiki’s golden beaches to Honolulu’s skyline, with the neighboring islands of Molokai and Maui visible on clear days. The early morning light transforms the scene into pure magic.
Kalalau Trail
Kauai’s legendary coastal path leads hikers along the dramatic Na Pali Coast, where emerald ridges slice into the Pacific like ancient daggers. The full 22-mile journey requires permits and serious preparation. But even the first two miles to Hanakapiai Beach reveal why this route earns its reputation as one of America’s most incredible hikes.
Koko Head Crater Trail
This brutal stair-climber follows 1,048 railroad ties straight up the side of an extinct volcano. Not for the faint of heart. The relentless ascent burns legs and lungs, but the 360-degree views from the top make every painful step worthwhile.
Look down into Hanauma Bay’s turquoise waters, across to Diamond Head, and out over southeastern Oahu’s coastline. The rusted military equipment scattered across the summit adds an intriguing historical element to this volcanic adventure.
Sliding Sands Trail
Haleakala National Park’s signature hike descends into what feels like another planet. The trail drops 3,000 feet over 11 miles into the massive volcanic crater, where cinder cones rise from an alien landscape of red rock and rare silversword plants.
And at sunrise, when most visitors arrive, the play of light across this Martian terrain creates one of Hawaii’s most unforgettable spectacles. The descent is easy; the return climb will test your endurance.
Lanikai Pillbox Hike
This short but rewarding trail on Oahu’s windward side leads to concrete World War II observation bunkers perched above paradise. The moderate 1-mile hike climbs 450 feet along Ka’iwa Ridge, offering increasingly stunning views with every step.
At the summit, hikers gaze down at Lanikai Beach’s powder-soft sand and turquoise waters, with the iconic Mokulua Islands floating offshore like green gems. Perfect for sunrise or sunset viewing.
Kilauea Iki Trail
Walk across a solidified lava lake in Hawaii Volcanoes National Park. This 4-mile loop descends through rainforest into the mile-wide Kilauea Iki crater, where steam still rises from vents that once spewed molten rock.
The contrast is remarkable—from lush tropical forest to barren moonscape in minutes. Rangers mark the safe route across the crater floor with stone cairns, guiding hikers through this otherworldly landscape.
Waihe’e Ridge Trail
Maui’s dramatic windward mountains come alive on this 5-mile ridgeline adventure. The trail climbs through native forest and along narrow ridges, revealing sweeping views of the island’s central valley and wild north coast.
Waterfalls cascade down distant cliffs while trade winds bend the forest canopy. The elevation gain of 1,500 feet demands effort, but the payoff includes some of Maui’s most pristine mountain scenery.
Makapu’u Lighthouse Trail
This paved path on Oahu’s southeastern tip offers easy access to dramatic coastal views. The 2-mile round trip is perfect for families, with gentle inclines leading to a historic lighthouse perched on towering sea cliffs.
Between November and May, humpback whales breach in the waters below. The trail also passes several World War II bunkers, adding historical intrigue to the spectacular ocean panoramas.
Awaawapuhi Trail
Kauai’s Kokee State Park harbors this challenging 6.5-mile trail that ends at one of the islands’ most spectacular viewpoints. The route descends through native forest before emerging on knife-edge ridges high above the Na Pali Coast.
The final viewpoint overlooks 3,000-foot cliffs plunging directly into the Pacific. Not great. The narrow ridges and steep drop-offs demand caution, but the views justify every careful step.
Manoa Falls Trail
Oahu’s most accessible waterfall hike winds 1.6 miles through a lush valley that served as a filming location for Jurassic Park and Lost. The easy trail can be muddy, especially after rain, but proper footwear handles the slippery sections.
The 150-foot waterfall tumbles into a small pool surrounded by towering tropical vegetation. Swimming isn’t allowed, but the cool mist provides perfect relief from Hawaii’s heat.
Pipiwai Trail
Haleakala National Park’s bamboo forest adventure leads to one of Hawaii’s most impressive waterfalls. The 4-mile round trip includes several smaller falls before reaching the towering 400-foot Waimoku Falls.
Walking through the dense bamboo grove feels like entering a natural cathedral. The bamboo creaks and sways overhead, creating an almost musical soundtrack for this magical journey through Maui’s rainforest.
Crouching Lion
This short but dramatic Oahu hike delivers big rewards for minimal effort. The 1-mile round trip climbs 300 feet to a rocky outcrop that resembles a lion in repose, offering panoramic views of Kahana Bay and the surrounding mountains.
Brave hikers can continue beyond the main viewpoint, but the initial stop provides plenty of scenery. The trail gets steep near the end, so proper footwear is essential.
Waimano Falls Trail
This steep but rewarding 3-mile hike on Oahu leads to a series of cascading waterfalls and deep swimming holes. The trail drops 800 feet through forest to reach the falls, making the return climb a serious workout.
Multiple jumping spots provide thrills for adventurous swimmers. The trail can be slippery when wet, and the steep sections require careful footing throughout the descent and ascent.
Aiea Loop Trail
Perfect for morning workouts or peaceful nature walks, this 4.8-mile loop trail circles through Oahu’s central mountains. The well-maintained path offers glimpses of Pearl Harbor and Honolulu through breaks in the forest canopy.
Native plants line the trail, including towering eucalyptus trees and colorful tropical flowers. The moderate elevation changes and good footing make this ideal for trail runners and casual hikers alike.
Koko Crater Arch
A hidden gem near the famous Koko Head stairs, this easier alternative explores the crater’s interior rim. The 2-mile trail leads to a natural rock arch with stunning views of Hanauma Bay and the surrounding coastline.
The arch itself frames the ocean beautifully, creating perfect photo opportunities. Unlike its stair-climbing neighbor, this trail offers shade and gentler grades while still delivering spectacular coastal scenery.
Kuliouou Ridge Trail
This challenging but rewarding 4.2-mile round trip climbs 1,650 feet through diverse terrain to reach one of Oahu’s finest viewpoints. The trail begins in ironwood forest before emerging onto exposed ridges with sweeping views of the Ko’olau Mountain Range.
From the summit plateau, hikers enjoy panoramic views stretching from Lanikai Beach to Diamond Head, with the entire windward coast spread below. The final ascent includes well-placed stairs that make the steep sections more manageable than they once were.
Trail wisdom for island adventures
Hawaii’s hiking trails demand respect for both safety and cultural significance. Many paths cross sacred Hawaiian lands, so tread lightly and follow all posted guidelines. Weather changes quickly in the mountains—pack layers, plenty of water, and sun protection. Most importantly, check trail conditions before departing, as heavy rains can make even easy trails dangerous within hours.
