Saddle Road is fine.
The rumors are twenty years old.

Where the bad reputation came from

Before the mid-2010s, Saddle Road was a narrow, bumpy, partly-single-lane track with blind crests and no shoulders. Rental companies universally prohibited it because the insurance risk was real. Breakdowns were common, cell service was non-existent, and tow bills were astronomical.

The federal government rebuilt it. Between 2007 and 2017, the highway was realigned, repaved, widened, and renamed after Senator Daniel K. Inouye. It's a different road today. Rental contracts caught up; most had lifted the restriction by 2013.

What Saddle Road is actually like now

A two-lane highway across one of the more surreal landscapes on Earth. You drive between two volcanoes that are each bigger than most islands. Grassland gives way to ʻōhiʻa forest gives way to 1984 Mauna Loa lava flow, a quarter-century-old black glass desert with a few brave ʻōhelo plants trying to colonize it.

It's also the fastest paved route between the Hilo and Kona sides. Alternative is Hwy 19 around the north (Hamakua Coast + Waimea), which is more scenic but adds 45+ minutes.

What to actually watch for

• Fog in the saddle. Visibility can drop to 50 feet near Pōhakuloa in the afternoon. Headlights on, go slow.
• Sudden weather. You can leave dry Kona and hit rain at the saddle within 20 minutes. The windshield wipers get a workout.
• No gas for 52 miles between Hilo and Waikōloa. Top off before you start. This is the single most common mistake visitors make on this road.
• Occasional cattle and goats in the open-range stretches near Pōhakuloa. Slow down, they don't look both ways.
• Military training area. The Pōhakuloa Training Area is an active US Army facility. Stay on the highway, don't pull off onto any marked restricted roads.
• Limited shoulders. The highway is wider than it was, but pullouts are real and scattered, not every mile. Plan your photo stops.

What connects to Saddle Road

• Mauna Kea Access Road. The paved climb to the Visitor Information Station at 9,200 ft. Full details in our Mauna Kea driving guide.
• Mauna Loa Observatory Road. Rough, unpaved, and not allowed in a rental. Skip.
• Waikōloa Beach Resort, Mauna Lani, Hapuna Beach. At the Kona-side end, Saddle drops you within 15 minutes of the major resort beaches.
• Hwy 190 (Māmalahoa) north to Waimea. Alternate connection if you're headed to the north Kohala district instead of south toward Kona.

Mini-FAQ

Is Saddle Road safe for rental cars?

About 1 hour 40 minutes from Hilo (ITO) to Waikōloa, and roughly 2 hours total from Hilo to Kailua-Kona depending on traffic through Waikōloa. Going the long way via Hwy 19 and the Hamakua Coast adds about 45 minutes.
