Hikes & Outdoor Adventures

Hawai‘i Volcanoes National Park
This park is like stepping into another world—lava tubes, smoking craters, and hikes that feel otherworldly. One of my all-time favorites is the Kīlauea Iki Trail, a 3.2-mile loop that takes you from lush rainforest down into a solidified lava lake formed during the dramatic 1959 eruption. You’ll literally walk across the crater floor, past steaming vents and jagged lava formations, with towering cliffs rising around you. It’s surreal in the best way. The trail is moderately challenging with a 400-foot descent and climb, but totally worth it for the views and the experience of walking where lava once flowed. Plan for a full day—you’ll want time to take it all in.

Pololū Valley Hike
This one is a must! The trail starts at the Pololū Valley Lookout and winds steeply down through ironwood trees and tropical greenery to a stunning black sand beach. At the bottom, the valley opens up into a peaceful, almost sacred-feeling space—think freshwater streams and lake, lush mountains and towering sea cliffs. There’s a rope swing tucked into the trees and plenty of driftwood to perch on while you take it all in. If you’re feeling adventurous, there’s a trail that continues up the far side of the valley toward Honokane Nui. It’s steeper and more rugged, so keep that in mind when you’re ready to leave—you’ll be climbing right away. But the views from the top are next level.

Parking tip: There’s a small lot at the end of Highway 270, but it fills up fast—especially on weekends. If it’s full, you can park along the road, just be sure to respect posted signs and private driveways. There are no restrooms or services at the trailhead, so plan accordingly (Keokea Beach Park nearby has facilities if needed).

Kaumana Caves
Just outside Hilo, this lava tube system was formed by an 1881 Mauna Loa eruption and is one of the coolest hidden gems on the island. You descend a steep metal staircase into a collapsed skylight, and from there, you can explore both directions of the cave. The entrance is naturally lit and easy to navigate, but if you’re up for more adventure, bring a headlamp and sturdy shoes—the cave stretches for over two miles under private land and is totally worth the exploration. We missed the tip on the head lamp and had to use our phone flashlights- so prepare accordingly for the amount of roaming you’ll be doing. Inside, it’s cool and damp, with the most incredible lava formations and a real sense of mystery. It’s an adventurous stop with the amount of crawling and climbing, but one that sticks with you.

Parking tip: There’s a small lot on the south side of Kaumana Drive, directly across from the cave entrance. It’s on a curve, so be extra cautious when crossing the road. The lot is free and usually has space, but it can get busy midday. Restrooms and picnic tables are available near the parking area, making it a convenient spot to regroup before or after your cave adventure.

Know Before You Go: Tips for Hiking & Exploring the Big Island

• Start Early: Trails like Pololū Valley and Kīlauea Iki can get hot and crowded later in the day. Morning light also makes for better photos (and cooler temps).

• Footwear Matters: Trails can be steep, rocky, or slippery—especially at Pololū and in Kaumana Caves. Sturdy shoes or hiking sandals are a must.

• Respect the Land: Many sites hold cultural and spiritual significance to Native Hawaiians. Stay on marked trails, pack out what you pack in, and show aloha wherever you go.

• Pack Essentials: Bring water, reef-safe sunscreen, snacks, and a flashlight or headlamp for lava tubes like Kaumana Caves. Cell service can be spotty, so download maps ahead of time.

• Parking Smarts: Pololū’s lot fills up fast—arrive early or be ready to park along the road respectfully. Kaumana Caves has a small lot across the street from the entrance; be cautious when crossing.

• Weather Shifts: The Big Island’s microclimates mean it can go from sunny to drizzly fast—especially around Hilo. A light rain jacket or poncho comes in handy.
