Exploring Hawaii's Wild Side
With over 300 miles of accessible trails weaving through diverse terrain, the Big Island of Hawai‘i is a true hiker’s paradise. From lush tropical rainforests and misty cloud forests to stark lava fields and sun-scorched deserts, this island offers a hiking experience like no other. In fact, 8 of the world’s 13 climate zones can be found right here, making every trail feel like a new adventure.
One of the crown jewels for hiking is Hawai‘i Volcanoes National Park (HVNP), which alone features more than 150 miles of maintained trails. Whether you're trekking across ancient lava flows, descending into volcanic craters, or exploring native ohia forests, HVNP offers a truly otherworldly experience. It’s a “must-do” for anyone living on or visiting the island.
Beyond the national park, the island is scattered with well-known hikes that vary in elevation, terrain, and difficulty. From coastal lava rock trails to waterfall treks and summit climbs, there’s something for everyone—from casual walkers to serious backcountry adventurers.
Keep in mind that many hiking destinations on the Big Island require a certain amount of drive time. It’s not uncommon to travel an hour or more to reach a trailhead—so plan ahead, pack accordingly, and always check weather conditions.

Na Ala Hele
“Na Ala Hele” is the State of Hawaii Trail and Access Program. It was established in 1988 in response to public concern about the loss of public access to specific trails and the threat to historic trails from development pressure.
Na Ala Hele has become increasingly engaged in trail management and regulatory issues, due to both public and commercial recreational activities, as well as emerging legal issues. Visit Na Ala Hele Website
Waipio Valley
Surreal Waterfalls, a Black Sand Beach, and Wild Horses...
Known as the Valley of Kings for its Alii (royal) Hawaiian history, Waipio Valley is one of the most spectacular locations in all of Hawaii. Featuring sweeping views from above with a black sand beach and hidden waterfalls below, this remote and isolated part of the Big Island is a must-do “bucket list” adventure.
Located approximately 20 minutes from Waimea, the hike down into the valley and up the other side (and then back to the parking lot) is nearly 5 miles, consisting of some fairly steep terrain. Starting from the parking lot at the top of Waipio Valley, the route is nearly 5 miles long. For more detailed info and planning logistics, read this excellent write-up at Hikespeak.
Pololu Valley
One of the Most Photographed Lookout Points in Hawaii...
Another epic Big Island hiking trail can be found at Pololu. This is a moderate hike switchbacking 420 ft down to the valley floor, where you will find Pololu Beach, a stunning black sand beach. You will also find numerous large boulders and some driftwood scattered around. The trail starts at the Lookout, located at the end of the road, 15 minutes past Hawi and the Puakea area.
CAUTION: The ocean here is quite sketchy, known for its massive undertow, high surf, and riptides. Do not go into the water. It is also essential that you remain on the trail beyond the beach. Much of the surrounding land is privately owned and consists of numerous sacred burial sites. An excellent overview of this hike can be found at lovebigisland.com.
Green Sand Beach
One of Only Four Green Sand Beaches in the World...
Papakolea Beach, commonly known as “Green Sand Beach” due to its unique olive-green sand, is located near the Big Island’s southern tip. This is one of the more “remote” locations on the island – essentially equating to a full-day trip, including drive time.
It is an excellent opportunity to experience the stark contrast in the natural beauty that makes the Big Island so special. The time and effort in getting there will be well worth it!
This is a relatively flat 5-mile round-trip hike. But do not be fooled, it can be quite strenuous due to the dust, heat, wind, and often sandy trail.
Akaka Falls
A Beautiful Hawaii Waterfall with Easy Accessibility.
This is a relatively easy 0.4-mile loop consisting of a paved footpath through lush tropical vegetation with a scenic point overlooking the 442-ft waterfall “Akaka Falls”. Perfect for families as it is short, convenient, and memorable.
1 hour from Waimea, Akaka Falls is on the east side of the Big Island along the beautiful Hamakua Coast. It is a State Park, so a small entrance fee is required. For more information, visit the Akaka Falls State Park Website.
Kaloko Trail
Best Trail for a Quick Hike, Just Minutes from Kailua-Kona.
A local favorite and one of the best Big Island hiking trails in the Kailua-Kona area. Kaloko consists of several short loops through the serene ohia and fern cloud forests located halfway up Kaloko Drive. It is located just 15 minutes from Historic Kailua Village, essentially in the backyard of Kalaoa and nearby Holualoa.
Most of the trail is relatively easy to moderate in difficulty, though some parts can be a bit more technical. There can be slippery exposed roots and rocks that you need to be aware of.
Kaloko Trail is popular during the early mornings and late afternoons, which aligns with people’s work schedules.
King's Trail
Bring Plenty of Water, Sun Protection, and Good Shoes.
The Ala Kahakai National Historic Trail (commonly known as the “King’s Trail”) is a cultural and historic shoreline trail. Built in the mid-19th century for horse travel, the trail once stretched 32 miles from Kailua-Kona north to Puako.
Numerous options exist for exploring specific sections of the trail, one bit at a time. Probably the easiest point of entry can be found at Waikoloa Beach Resort near the gas station (look for the nearby trailhead signs).
*The trail is very exposed, so ideally you should aim to go early in the morning or later in the day to avoid the blazing sun. Visit the Ala Kahakai Website for more info.
Pu'u Wa'awa'a
A Bird-Watching Paradise, Great for Running Too.
This is a fantastic Big Island hiking area conveniently located near Puuanahulu, just 10 miles north of Kailua-Kona. Puʻu Waʻawaʻa features beautiful trails that are easy to moderate in difficulty.
The main hike to the summit of the cinder cone is approximately 7 miles round-trip. Once at the top, you will be able to enjoy magnificent distant views of the Kohala Coast.
