The best walks and hikes around Mauna Loa

The Kawa'a Beach Trail offers a unique, easy escape to a secluded black sand beach on the Big Island. This short 0.5-mile (0.8 km) hike, with virtually no elevation gain, leads you through a landscape of lava rock and shrubland before revealing Kāwā Bay, a hidden gem with numerous tidepools and freshwater springs. It's a perfect, quick adventure for those seeking a tranquil coastal experience without a strenuous trek.

To access the trail, you'll follow a lava road from the highway; consider a high-clearance vehicle or be prepared for a 15-minute walk if parking by the highway. The entire journey takes only about 12 minutes, making it an ideal stop for a quick exploration. Remember to bring your own water and snacks, as there are no facilities at the bay, and always practice Leave No Trace principles to preserve this special place.

Beyond its natural beauty, Kawa'a Beach holds deep cultural and historical significance, with ancient structure remains like Ke'eku Heiau in the area. It's also a vital conservation site, protecting nesting areas for the critically endangered Hawaiian hawksbill turtle. This trail offers a chance to connect with both the natural and cultural heritage of Hawaiʻi County, making it a truly notable destination.

Embark on a journey through ancient Hawaiian history along the Ala Kahakai National Historic Trail (1871 Trail), a moderate 2.1-mile (3.3 km) hike that offers a unique blend of culture and coastal beauty. With only 47 feet (14 metres) of elevation gain, this route is more about the experience than the exertion, guiding you past stark black lava fields, white sands, and swaying coconut groves. You'll feel transported back in time as you explore this significant stretch of coastline, perfect for those seeking a meaningful and scenic walk.

This accessible section of the 1871 Trail is conveniently located within Puʻuhonua o Hōnaunau National Historical Park, where parking is readily available. To make the most of your visit and avoid the midday heat, plan to start your hike in the cooler morning hours. Remember to bring plenty of water, as the coastal climate can be quite dry, ensuring a comfortable and enjoyable exploration of the trail.

The Ala Kahakai National Historic Trail is not just a path; it's a living museum, preserving ancient Hawaiian pathways used for travel and trade. This particular segment, the 1871 Trail, is notable for its historical improvements to accommodate horse traffic and passes through numerous archaeological remains, including ancient ramps and remnants of coastal fishing villages.

Hike the easy 2.1-mile Manukā Nature Trail loop through a cool Hawaiian forest, exploring lava flows and a pit crater.

Step back in time on the Footprints Trail, an easy 4.0-mile (6.5 km) hike through the otherworldly Kaʻū Desert. This route, which takes about 1 hour and 43 minutes with a gentle 218 feet (66 metres) of elevation gain, offers a fascinating journey across old lava flows and volcanic ash. The main draw is the Footprints shelter, where you can witness ancient human footprints preserved in volcanic mud, a truly unique sight in this desolate yet captivating landscape.

Access the trail from the Kaʻū Desert Trailhead on Highway 11. While the path is generally easy and family-friendly, be aware that some sections can be uneven or have deep sand. The elevation of around 3,500 feet means cooler temperatures, so dress accordingly. Dogs are permitted on the trail, provided they remain on a leash.

This trail is a profound connection to Hawaii's geological and human history, showcasing the raw power of Kīlauea Volcano. The fossilized footprints tell a dramatic story of ancient Hawaiians encountering a massive eruption in 1790, making it a significant cultural and natural landmark. It's a must-do for anyone interested in the island's past and its unique volcanic environment.

The Pu'u o Lokuana Trail offers a captivating and easy 2.7-mile (4.4 km) hike through a landscape shaped by both volcanic activity and human history.

The route culminates at the Puʻu o Lokuana cinder cone, where you can explore a historic "crimson heart" quarry and enjoy panoramic views of the Kahuku area and the Kaʻū coastline.

Planning your visit is straightforward, though sturdy footwear is advisable for the varied, sometimes rocky and grassy terrain, especially on the ascent to the cinder cone. As with many Hawaiian trails, an early start or late afternoon hike can provide cooler temperatures and optimal lighting for the scenic viewpoints. There are also longer Pu'u o Lokuana Trail loop options if you want to extend your adventure.

This trail is notable for its rich historical context; the cinder cone was once significantly taller before being mined for its vibrant cinders, and it even housed a secret radio station during World War II. It's a fantastic way to experience the dynamic interplay of natural features like magma formations and grasslands with significant human events, offering a unique glimpse into the Kahuku landscape.
