Overview

About This Trail

This moderate out-and-back hike descends 1 mile down the Keoneheʻeheʻe (Sliding Sands) Trail into Haleakalā's volcanic crater on a steep, sandy cinder slope. The descent is deceptively easy; the return tests you at altitude. The crater floor sprawls below scattered with cinder cones (puʻu) formed within the last 1,000 years—raw volcanic geology on display. You'll find the endangered ʻāhinahina silversword clinging to life where few plants survive. Full sun, constant wind, loose footing, 10,000 feet elevation: this is a grit check. The payoff is profound—you're inside an otherworldly volcanic arena.

Trail Highlights

Stand inside one of Earth's most alien ecosystems at 10,000 feet. The crater floor sprawls below scattered with cinder cones of different ages, the youngest erupted within the last 1,000 years. Witness the rare, endangered ʻāhinahina silversword adapted to survive intense sun and desert conditions where almost no other plant can exist. This is raw volcanic geology: wind, exposure, and the profound silence of stone.

Insider Tips

• The 'natural overlook' at 1 mile isn't the absolute trail end—switchbacks continue below—but the 1-mile point is the recommended moderate turnaround with stellar views.\n• The descent feels deceptively easy; the return climb will humble you at altitude. Pace accordingly and take breaks.\n• Early light (6–8am) illuminates the cinder cones beautifully and minimizes afternoon cloud cover.\n• The ʻāhinahina silversword plants are fragile and endangered. Stay on trail to protect them.\n• The return climb is roughly twice as long as the descent. Budget your energy accordingly.

Best Season to Hike

Year-round operation. Spring and fall offer the most stable weather. Winter is Hawaii's rainy season with increased afternoon fog and storm risk.

Hiking Tips

  • Bring 2+ liters of water minimum. No reliable water sources on the trail; dehydration at 10,000 ft happens fast.\n
  • Start before 7am to avoid afternoon fog, storms, and heat.\n
  • Zero shade on cinder slope. Wear sunscreen, hat, sunglasses. Wind is relentless.\n
  • Tighten your boots. Loose cinder is unstable underfoot—ankle twists are common.\n
  • Trekking poles reduce knee stress on the steep descent and help anchor you on the return climb.\n
  • On the return, take switchbacks slowly and deliberately. The climb at altitude is harder than the descent.\n
  • Make noise on the trail. Nēnē (Hawaiian geese) are present but non-aggressive.

Family Info

The high altitude (10,000 ft), steep terrain, loose footing, and intense sun make this trail challenging for young or inexperienced children. Hand-holding is required on steep sections. Children must be confident, experienced hikers. Families just arriving in Hawaii should acclimatize at lower elevations first before attempting this hike.

What Hikers Say

Hikers consistently praise the otherworldly crater views and geological drama as worth the physical effort. The high altitude and loose terrain are the main difficulty factors, not technical skill. Most hikers report the return climb is significantly harder than the descent due to altitude, steepness, and fatigue. First-time high-altitude visitors should expect to move slowly and take frequent breaks.
