Volcanoes National Park: Land of Fire and Earth

Volcanoes National Park on the Big Island is a must-visit for any hiker. It offers a unique glimpse into the power of volcanic activity and the incredible landscapes it creates. Here are some of the park’s standout trails:

Kīlauea Iki Trail

This 4-mile loop descends into the Kīlauea Iki crater, a solidified lava lake. The trail begins through a lush rainforest before opening up to the stark, otherworldly landscape of the crater floor. Walking across the crater is an unforgettable experience, with vents releasing steam and the surrounding crater walls towering above. The Kīlauea Iki Trailhead is easily accessible from Crater Rim Drive. The entire hike could take 2-3 hours.

Tips for Hiking Kīlauea Iki: Bring plenty of water as there is little shade on the crater floor. Wear sturdy shoes as the terrain can be uneven. Be aware of the steam vents and avoid getting too close, as the steam can be hot. Consider hiking early in the morning to avoid the midday heat.

Crater Rim Trail

For a less strenuous option, consider the Crater Rim Trail, which offers panoramic views of the Kīlauea caldera and surrounding volcanic landscapes. This trail has various access points, allowing you to customize your hike’s length. A popular section is the walk from the Jaggar Museum (now closed due to earthquake damages) to the Kīlauea Overlook. This section is partially paved and offers stunning views of the Kīlauea caldera. However, always refer to the official National Park Service website for updated trail closures and safety advisories, as volcanic activity can cause closures.

Tips for Crater Rim Trail: Bring binoculars for a closer look at the volcanic landscape. Wear sunscreen and a hat, as there is limited shade. Check the park’s website for updates on volcanic activity and trail closures. Be aware of altitude sickness, especially if you are not used to hiking at higher elevations.

Thurston Lava Tube (Nāhuku)

This short, paved trail leads through a 500-foot-long lava tube formed centuries ago. It’s a fascinating walk through a natural tunnel, offering a glimpse into the volcanic processes that shaped the islands. The Thurston Lava Tube is easily accessible and suitable for all ages and abilities. It is a great place to start if you want a quick exploration of the volcanic region. However, it can become crowded during peak hours.

Tips for Thurston Lava Tube: Bring a flashlight even though the tube is illuminated, as some areas are darker than others. Be aware of slippery surfaces, especially after rain. Arrive early or late in the day to avoid the crowds.

Maui’s Majestic Trails: From Haleakalā to the Coast

Maui offers a diverse range of hiking experiences, from the otherworldly landscapes of Haleakalā National Park to the lush rainforests of the Road to Hana. Here are a few of Maui’s must-do hikes:

Sliding Sands Trail (Haleakalā)

This challenging trail descends into the heart of Haleakalā Crater, offering a unique perspective on the park’s volcanic landscape. The trail is steep and can be strenuous, but the views are well worth the effort. The full trail is 11.3 miles long out-and-back, considered very challenging. For an easier option, hike a shorter distance into the crater and then turn around.

Tips for Sliding Sands Trail: Bring plenty of water, as there is no water available on the trail. Wear sturdy shoes, as the terrain can be uneven and slippery. Be prepared for rapid changes in weather; temperatures can drop significantly inside the crater. Wear sunscreen and a hat, as there is little shade.

Pipiwai Trail (Road to Hana)

Located within Haleakalā National Park but accessible from the Road to Hana, the Pipiwai Trail is unlike anything you’ve seen. This 4-mile roundtrip hike leads through a bamboo forest and past several waterfalls, including the impressive Waimoku Falls. It’s a relatively easy hike, but it can be muddy, especially after rain.

Tips for Pipiwai Trail: Wear waterproof shoes or sandals, as the trail can be muddy. Bring insect repellent, as mosquitoes can be prevalent. Be prepared for rain, as the area is known for frequent showers. Watch out for slippery rocks and roots along the trail. Pack a swimsuit if you want to take a dip in the pools below the waterfalls, but be cautious of strong currents and submerged rocks. The National Park Service advises against swimming in the pools above Waimoku Falls due to the danger of falling rocks. This trail requires a reservation; book in advance on Recreation.gov.

This 11-mile trail (one way) follows the rugged Na Pali Coast, offering breathtaking views of towering cliffs, secluded beaches, and lush valleys. The full trail requires a permit and is only suitable for experienced hikers due to its challenging terrain, exposure to cliffs, and stream crossings.
