Big Island Hiking Trails

Captain Cook Trail (Ka'awaloa)

Captain Cook

The Captain Cook Trail offers one of Hawaii Island's most rewarding yet challenging hiking experiences, combining stunning natural beauty with significant historical importance. This strenuous 3.6-mile round-trip trail descends 1,400 feet through diverse terrain to reach the pristine shores of Kealakekua Bay on the Kona Coast. The trail begins in Captain Cook and winds downward through native vegetation and lava rock formations. While the descent challenges hikers with steep grades and uneven surfaces, the dramatic views of Kealakekua Bay's crystal-clear waters provide motivation throughout the journey. The turquoise bay, protected as a marine life conservation district, comes into full view as you approach the bottom. At trail's end, hikers discover the white obelisk marking the Captain Cook Monument, commemorating where the famous explorer met his fate in 1779. This historic site sits adjacent to some of the Big Island's most exceptional snorkeling waters. The bay's protected status has preserved vibrant coral reefs teeming with tropical fish, spinner dolphins, and Hawaiian green sea turtles. The return climb proves significantly more demanding than the descent, requiring good physical conditioning and plenty of water. Starting early morning helps avoid the intense afternoon heat that can make the ascent particularly grueling. Despite the challenging nature, this free trail rewards prepared hikers with an unmatched combination of natural beauty, world-class snorkeling, and Hawaiian history that few other Big Island attractions can match.

Devastation Trail

Volcano

The Devastation Trail offers a unique glimpse into the raw power of volcanic eruptions on Hawaii's Big Island. This easy half-mile paved walkway winds through a landscape forever changed by the 1959 Kilauea Iki eruption, making it one of the most accessible and educational hikes in Hawaii Volcanoes National Park. The trail takes its name from the dramatic scene that greeted visitors after the eruption – a moonscape of pumice and volcanic debris where lush rainforest once thrived. Today, over six decades later, you'll witness nature's remarkable recovery as native plants slowly reclaim the volcanic terrain. Ohia lehua trees and hardy ferns push through the porous rock, creating a living laboratory of forest regeneration. Perfect for families and photographers, the fully paved path requires minimal physical effort while delivering maximum impact. The stark beauty of bleached tree skeletons contrasting with new growth creates compelling photo opportunities throughout your walk. Interpretive signs along the route explain the geological processes that shaped this unique ecosystem. The trail connects conveniently to the Kilauea Iki Trail for those seeking a longer adventure, though many visitors find the Devastation Trail complete and satisfying on its own. Plan 30-45 minutes for a leisurely round trip, allowing time to absorb the landscape's powerful story of destruction and renewal. Access to Devastation Trail is included with Hawaii Volcanoes National Park admission ($30 per vehicle). The trailhead features parking and restroom facilities, making this an ideal introduction to the volcanic wonders that define Hawaii Island.

The Pu'u Huluhulu Trail offers one of Hawaii's most rewarding short hikes, delivering spectacular panoramic views with minimal effort. This easy 20-minute trek up a small cinder cone near Volcano on Hawaii's Big Island provides visitors with the rare opportunity to see three massive volcanoes—Mauna Kea, Mauna Loa, and Hualalai—simultaneously from a single vantage point.

The well-maintained path makes it perfect for families, casual hikers, and anyone seeking impressive volcano views without committing to a full-day adventure. From the summit viewpoint, the expansive landscape reveals why the Big Island captivates visitors. On clear days, the sight of these three volcanic giants dominating the horizon creates an unforgettable perspective of Hawaii Island's dramatic geology. Mauna Kea's snow-capped peak often contrasts beautifully with Mauna Loa's broad slopes and distant Hualalai. The trail's gentle incline and short distance make it an ideal introduction to Big Island hiking, while the native vegetation provides insight into Hawaii's original ecosystems.

Mauna Kea Summit Trail (Humuʻula)

Waimea

The Mauna Kea Summit Trail (Humuʻula) offers ambitious hikers the chance to stand atop Hawaii's tallest peak at 13,796 feet above sea level. This challenging 6-mile one-way trail on the Big Island takes you from the Visitor Information Station at 9,200 feet to the highest point in the Hawaiian Islands. The strenuous trek demands serious preparation due to extreme altitude conditions. Hikers must acclimatize at the visitor station for at least 30 minutes before attempting the summit, as altitude sickness poses a real risk at these elevations. The trail climbs nearly 4,600 feet over rocky volcanic terrain, requiring excellent physical fitness and proper gear. Starting from Waimea in the Kohala Coast region, the summit trail forms part of the larger Mauna Kea Summit area. The reward for completing this demanding hike is unparalleled – panoramic views across the Pacific Ocean and neighboring islands, plus access to one of the world's premier stargazing locations. Weather conditions change rapidly at altitude, so pack layers and rain gear even on sunny days. The thin air and UV exposure at this elevation intensify quickly. Many hikers begin before dawn to avoid afternoon weather and experience sunrise from Hawaii's rooftop. This free trail attracts serious hikers and astronomy enthusiasts from around the globe. The summit's clear skies and minimal light pollution create extraordinary stargazing opportunities, making the challenging ascent worthwhile for those properly prepared for high-altitude hiking.

Pololū Valley Trail

Hawi

The Pololū Valley Trail offers one of Hawaii Island's most rewarding short hikes, leading adventurers down a steep 0.8-mile path to a stunning black sand beach in North Kohala. This moderate trail begins at the scenic Pololū Valley Lookout near Hawi and descends through lush vegetation into a dramatic valley carved by centuries of wind and water. The trail itself challenges hikers with its steep, sometimes muddy terrain, but the payoff is spectacular. At the bottom, you'll find yourself on a remote black sand beach where towering valley walls create a natural amphitheater around the Pacific Ocean. The contrast between the dark volcanic sand, green valley walls, and blue ocean creates some of the most photogenic scenery on the Big Island. Morning visits are ideal when temperatures are cooler and lighting is perfect for photography. The trail can become slippery when wet, so proper hiking shoes are essential. While the descent takes about 20-30 minutes, remember that the return climb is more strenuous and typically takes 30-45 minutes. Free to access, the Pololū Valley Trail represents the raw beauty of Hawaii's North Kohala coast. The beach at the bottom is perfect for exploring tide pools and enjoying the dramatic coastal views, though swimming isn't recommended due to strong currents. This hidden gem provides an authentic Hawaiian wilderness experience just a short drive from the historic town of Hawi.

Waipi'o Valley Trail

Waipio Valley

The Waipi'o Valley Trail on Hawaii's Big Island takes you down the steepest road in all of Hawaii—a dramatic 25% grade descent into one of the most sacred places in Hawaiian culture. Known as the "Valley of the Kings," Waipi'o Valley served as the political and spiritual center of ancient Hawaii, where Hawaiian royalty once lived and ruled. This strenuous hike challenges visitors with its incredibly steep terrain, but the rewards are extraordinary. The valley floor opens up to reveal lush taro fields, cascading waterfalls, and wild horses roaming freely through this untouched paradise. At the valley's end, a stunning black sand beach meets the powerful waves of the Pacific Ocean, creating a scene that feels completely removed from the modern world. The trail requires serious preparation and stamina. Only 4WD vehicles can safely navigate the treacherous road, though many visitors choose to walk the entire route—a decision that adds significant time and physical demand to the journey. The descent alone takes most hikers 30-45 minutes, with the return climb being considerably more challenging. Located along the Big Island's scenic Hamakua Coast, Waipi'o Valley maintains its spiritual significance for Native Hawaiians today. Visitors should approach this sacred space with respect and cultural sensitivity. The trail offers no facilities, so bring plenty of water, snacks, and sun protection.
