Pā Kaʻoao (White Hill) Trail

Why this short hike punches above its weight

If you’re at the summit area, Pā Kaʻoao is the highest return on investment you’ll find: a half-mile round trip with roughly 100 feet of gain that delivers a sweeping, unobstructed look into Haleakalā’s vast summit basin. Many visitors say the vantage here actually beats the views from the nearby Visitor Center and even Red Hill. The trail starts right outside Haleakalā Visitor Center (around 9,740 feet), climbs a small cinder cone, and ends on a rocky overlook perfect for soaking in the scene.

The experience

The path is short but can feel punchy at this elevation. Expect a rocky tread with loose volcanic gravel and a few uneven steps. Take it slow—thin air is the real challenge here. It’s popular and often busy around sunrise, but even then the views feel big and wild: Red Hill and the observatory stand out, and on very clear days you may spot the Island of Hawaiʻi’s volcanic summits on the horizon.

Geology and culture

You’re climbing a cinder cone—built from lava fragments blasted from the volcano and piled into a cone. Along the hill are more than 100 archaeological features (stone enclosures, or pā) built by Native Hawaiians between the 15th and 17th centuries, likely used as shelters by summit travelers. The modern trail itself was constructed in 1934 by the Civilian Conservation Corps, adding a New Deal chapter to this already rich cultural landscape.

Tips, gear, and logistics

• Distance: about 0.5 miles total (out-and-back) with ~100 feet of gain.
• Footing: rocky, with loose cinders—wear sturdy shoes with traction.
• Weather: the summit is cold, windy, and fickle year-round; it can be near freezing at dawn even in summer. Dress in layers.
• Protection: stay on the marked path to avoid damaging fragile ecosystems and archaeological sites.
• Parking: use the Haleakalā Visitor Center lot (same area used for the Sliding Sands Trailhead).
• Sunrise entry: 3–7 am requires a sunrise reservation for the summit district; without one, you can enter after 7 am.

Best time to hike

Year-round, but sunrise and sunset bring the most dramatic light. For sunrise, arrive well before dawn to find a spot, settle in, and give your body a minute to adjust to the altitude. If strong winds or clouds are hammering the Visitor Center viewpoint, this little cone often sits just high enough to eke out a better look.

If you want more

Craving a deeper dive into the crater landscape? The Sliding Sands Trail begins from the same parking area and heads straight into the basin for a much longer day out.
