Haleakala Sliding Sands Trail Access Road
Paved road to Hawaii's house of the sun
The paved Haleakala Crater Road climbs 36 miles from sea level to 10,023 feet through multiple climate zones, ending at the Visitor Center where the Sliding Sands Trail drops into the massive crater. This isn’t a technical off-road route but an epic mountain drive that tests your vehicle’s cooling system and brakes on the return descent. The road passes through upcountry ranches, eucalyptus forests, and finally the stark alpine desert where silversword plants cling to volcanic cinder.
Any vehicle can make this climb, but check your brakes and coolant before starting. Morning drives offer the best chance for clear summit views and catching sunrise above the clouds. Temperatures can drop to near freezing at the summit even when it’s 80°F at sea level, so pack layers. The reward is standing at the edge of a 7-mile-wide crater that looks more like Mars than Hawaii, with views stretching to the Big Island on clear days.

Frequently asked questions
Can I drive this road in a rental car or do I need 4WD?
Any vehicle can make this drive - it's entirely paved road to the summit. Even economy rental cars handle it fine, though they'll work harder on the steep grades.
Is the summit road open year-round or does it close in winter?
The road stays open year-round, but occasional ice at high elevations can cause temporary closures. Check park alerts before heading up, especially in winter months.
Do I need to pay park entrance fees to drive to the summit?
Yes, you'll pay the standard Haleakala National Park entrance fee at the gate. Current fee is $30 per vehicle, valid for 3 days.
How steep and curvy is the hardest section of this climb?
The road gains over 10,000 feet in 36 miles with constant switchbacks and grades up to 10%. Take your time - it's a 2+ hour drive up with plenty of brake-burning descents.
Should I worry about altitude sickness driving to 10,000 feet?
Some people feel lightheaded or short of breath at the summit, especially if coming from sea level. Stay hydrated and take breaks if you feel dizzy or nauseous.
