Pu‘u o Lokuana Trail (Kahuku)

Why go

This is the Kahuku Unit’s quick-hit viewpoint: a short loop up a red cinder cone with outsized panoramas of the Ka‘ū coast, Mauna Loa’s slopes, and open ranchlands. At just 0.4 miles total (a compact loop), it’s a fast, satisfying stop with plenty of geology and local history built in.

Trail experience

The path starts gently, then tackles a brief but steep climb on loose volcanic cinder to reach the cone’s rim. Up top, a loop circles the summit, delivering multiple lookouts and interpretive signs about the area’s volcanic past and ranching heritage. The trail is exposed with little shade and can be windy—expect bright sun, crunchy cinder underfoot, and big sky views. It’s typically quiet compared to the park’s main district.

Is it for you?

Short distance, modest elevation, and a touch of steepness make this an easy outing for most, but the loose cinder demands decent footwear and attention. It’s not wheelchair or stroller friendly, and pets aren’t permitted on Kahuku trails (service animals excepted). If you want a longer walk afterward, pair it with other short Kahuku routes like the Palm Trail or Pit Crater Trail.

Tips

• Start early for cooler temps and clearer coastal views, and bring water, a hat, and sunscreen—shade is minimal.
• Expect wind on the rim and watch footing on the steep cinder section.
• Kahuku isn’t open daily—check current hours before you go. Ranger-led talks or hikes are occasionally offered here and can add context.

Best time to hike

Year-round, with the sweetest light and temperatures in the morning. Winter and spring are especially pleasant thanks to cooler weather and seasonal blooms. Afternoons can be hot, hazy, and windy on this exposed cone.
