How long is Mana Road on Big Island?

Psst! Wanna know a local secret on the Big Island of Hawai'i? It's called Mana Road, and trust me, it's an adventure you won't forget. But fair warning, this isn't your typical Sunday drive.

This 42.9-mile (69km) dirt road connects Mauna Kea Access Road with the Mamalahoa Highway near Waimea and climbs around Mauna Kea, the island's majestic peak, topping out at 7,293 feet (2,223m).

Now, about the road itself: It starts paved, but quickly turns into a wild mix of loose rocks, red dirt, and hard-packed gravel that'll keep you on your toes. It's one of the oldest dirt roads on the island.

Is it dangerous? It *can* be. That red dirt turns treacherous in bad weather, plus the road is narrow and steep in sections. Forget about taking your rental car on this one, even if it's a 4x4! Rental companies strictly prohibit it.

On a good day, though, you might not even *need* four-wheel drive, but high ground clearance is a must because of some serious ruts. If the weather turns sour, get ready for a real off-road experience. Rain turns everything to mud, so it’s best avoided in those conditions. And be prepared for anything from strong winds to sudden downpours to blazing sunshine. Pack plenty of water and fuel!

Set aside about 5-6 hours to tackle this remarkable drive. You'll wind through open ranchlands, conquer challenging uphill climbs, navigate fast descents, and soak in incredible views of the volcano. It's a raw, rugged, and unbelievably scenic adventure!
