Whether you’re a seasoned hiker looking for a challenge or a beginner wanting a gentle stroll, you’ll find a trail to suit your needs. Many of these trails aren’t just scenic; they’re also steeped in cultural and historical significance.
This guide is designed to help you plan an unforgettable hiking adventure in Hawaiʻi Volcanoes National Park. We’ll cover some of the best trails, what to expect on each one, and how to make the most of your visit.
Preparing for Your Volcanic Hiking Adventure
Hiking in a place as unique as Volcanoes National Park requires a little planning and preparation. Here’s what to consider before you go.
Essential Gear and Checklist
Having the right gear is key to enjoying your time in the park. Be sure to bring:
- Sturdy hiking shoes
- A rain shell (weather can change quickly)
- Sunscreen
- A water bladder
- Blister protectors
Also, keep safety in mind. Before you head out on any trail, check the weather forecast and make sure the trail is open. Pack plenty of food and water, and be aware of potential hazards like sulfur emissions and any recent volcanic activity.
Planning and Booking
Accommodations and rental cars on the Big Island can be scarce, so it’s a good idea to book those in advance. Check sites like VRBO and Discover Cars for good deals.
If you plan to visit other national parks in the U.S., consider buying a National Park Pass, also known as the “America the Beautiful Pass.” It can save you money on entrance fees.
Iconic trails around the Kīlauea Caldera
If you’re looking for a memorable hike, you can’t go wrong with one of the trails circling the Kīlauea Caldera. Here are a few of the most popular:
Kīlauea Iki Trail
The Kīlauea Iki Trail is a 3.4-mile trek through rainforest and otherworldly volcanic landscapes. The trail descends into the Kīlauea Iki crater, where you’ll be surrounded by fascinating terrain.
For a more gradual climb, hike the trail clockwise, starting your hike from the parking area at the Kīlauea Iki Overlook. The trail descends about 400 feet into the crater.
Crater Rim Trail
The Crater Rim Trail is a long, famous trail that loops around the Kīlauea Caldera. From the trail, you’ll have phenomenal views of the Halemaʻumaʻu crater and the stark volcanic landscape.
Keep in mind that parts of the trail may be closed due to high sulfur emissions or volcanic activity. The one-way distance of the Crater Rim Trail is 7.6 miles.
Nāhuku (Thurston Lava Tube)
The Nāhuku, also known as the Thurston Lava Tube, gives you an up-close look at a lava tube that’s easily accessible from the trail. The walk through the tube takes about 20 minutes over a distance of 1/3 of a mile.
To avoid the crowds, try to arrive early or late in the day.
Exploring trails beyond the caldera: Cultural and geological wonders
While the Kīlauea caldera is the park’s focal point, several trails offer incredible insights into both the cultural and geological history of the area.
Puʻu Loa Petroglyphs Trail
The Puʻu Loa Petroglyphs Trail is an easy 1.3-mile (2.1 km) out-and-back hike that leads to a field containing more than 23,000 ancient Hawaiian carvings. These petroglyphs hold deep cultural significance, representing stories, beliefs, and observations of the Native Hawaiians who once lived on this land.
Haʻakulamanu (Sulphur Banks) Trail
For a different kind of geological wonder, try the Haʻakulamanu (Sulphur Banks) Trail. This accessible 1.3-mile (2.1 km) trail (1.2 miles/2 km roundtrip) winds through an area dotted with sulfurous vents and colorful mineral deposits. The air here carries a distinct sulfuric odor, a reminder of the volcanic activity beneath your feet.
Devastation Trail
The aptly named Devastation Trail offers a glimpse into the raw power of volcanic eruptions and the resilience of nature. This easy, paved trail is about a mile long and takes about 30 minutes to walk. It winds through a landscape transformed by a past eruption, showcasing the stark beauty that can emerge from destruction.
Venturing Further: Less-Traveled Trails and Unique Perspectives
While the popular trails offer incredible experiences, Volcanoes National Park also has some lesser-known gems for those seeking solitude and unique landscapes.
Mauna Loa Trail
For a truly challenging adventure, consider the Mauna Loa Trail. This strenuous hike leads to the Red Hill Cabin at a high elevation, rewarding you with unparalleled views and a stark volcanic landscape. Be prepared for a significant elevation gain and changing weather conditions.
- Mauna Loa Trail (to Red Hill Cabin): 15.0 miles (22.5 km)
Halemaʻumaʻu Trail
The Halemaʻumaʻu Trail offers a closer look at the Kīlauea caldera. You can even extend your hike to create a loop for a more immersive experience.
- Halemaʻumaʻu Trail: 1.6 miles (2.6 km)
The one-way distance is 1.8 miles.
Kīpuka Puaulu Trail
The Kīpuka Puaulu Trail, also known as Bird Park, is a relatively easy loop trail through a kipuka, an “island” of older forest surrounded by more recent lava flows.
- Kīpuka Puaulu Trail: 1.2 miles (1.9 km)
Staying Safe and Hiking Responsibly
Before you head out, make sure you check the National Park Service website for trail conditions and closures. Volcanic landscapes change constantly, and you don’t want to be caught off guard.
It’s also important to respect the delicate environment. Please stick to marked trails and avoid disturbing any plants or animals. Did you know that 90% of the native plants in Volcanoes National Park can’t be found anywhere else on Earth? Let’s keep it that way.
Finally, be prepared for anything. The weather in the park can change quickly, so pack layers of clothing and gear for both wet and dry conditions. Even if the forecast looks clear, it’s always a good idea to be prepared for rain.
In Closing
From short, paved strolls to intense backcountry treks, Hawaiʻi Volcanoes National Park offers a huge variety of hiking experiences. Whether you’re eager to explore active volcanic landscapes, delve into Hawaiian culture, or discover unique ecosystems, there’s a trail waiting for you.
So, start planning your own hiking adventure! But remember to put safety first. Be sure to check current conditions, wear appropriate gear, and pack plenty of water and snacks.
Hiking in a volcanic landscape is an unforgettable experience, and Hawaiʻi Volcanoes National Park is the perfect place to begin.
