Highway to the Stars: Why Saddle Road is Hawai‘i’s Most Stunning Drive
Some roads are just roads there to get you from Point A to Point B, but Saddle Road on Hawai‘i’s Big Island? It’s something entirely different. Often called the “Highway to the Stars”, this is more than just a scenic drive; it’s a journey through stark lava fields, misty cloud forests, and ancient volcanic landscapes that feel almost otherworldly. With elevation climbs topping 6,600 feet and views that stretch from coast to coast, it’s one of the most unforgettable Big Island attractions you’ll ever experience.
For guests staying at our Hawaii bed and breakfast, Saddle Road is an easy day trip that shows off the island’s raw beauty in a way no other drive can. If you’re looking to stargaze, take out-of-this-world photos, or just venture out for a peaceful road trip with jaw-dropping scenery, Saddle Road should be at the top of your Big Island itinerary.
The Route Itself: What Is Saddle Road?
Stretching for just over 50 miles, Saddle Road (officially known as Daniel K. Inouye Highway) connects Hilo on the east side of the island to Waimea and the Kona Coast on the west. What makes this stretch of highway so extraordinary isn’t just its length; it’s what you’ll pass along the way.
Built in 1942 for military use, Saddle Road has transformed over the years from a rough, pothole-filled path into one of the island’s smoothest and safest roads. As you climb to 6,632 feet in elevation, the landscapes shift dramatically. One minute you’re surrounded by dense rainforest, and the next you’re driving across miles of barren, hardened lava rock. Cloud banks roll in unexpectedly, the temperature drops, and you might even spot wild goats or birds along the way.
While it may look remote, Saddle Road is fully paved and in excellent condition today. There are no gas stations along the route, though, so make sure to fuel up before you head out and watch out for wildlife, there are a lot of wild goats and pigs along the road.
Must-See Stops and Sights Along Saddle Road
Driving along Saddle Road is an experience in itself, but these stops make the journey even more unforgettable:
Mauna Kea Access Road
About halfway along Saddle Road, you’ll spot the turnoff for Mauna Kea Access Road, the gateway to some of the world’s most famous observatories. If the weather is clear and your vehicle is up to the challenge, you can drive up to the Visitor Information Station at 9,200 feet. From here, visitors often stay to watch the sunset or join ranger-led stargazing programs. Keep in mind that access to the summit is limited and requires preparation, but even just visiting the mid-level station offers incredible views of the stars and surrounding landscapes.
Puʻu Huluhulu
If you’re looking to stretch your legs, Puʻu Huluhulu offers a short but scenic hike. This forested cinder cone rises like an island surrounded by vast lava flows. The trail leads to panoramic views of both Mauna Loa and Mauna Kea, making it a rewarding stop without requiring much time or effort.
Endless Lava Landscapes
Much of Saddle Road cuts through miles of rugged lava fields. These vast, moonlike expanses are the result of past eruptions from Mauna Loa and Mauna Kea. While it might seem desolate, these landscapes are geologically fascinating and offer excellent photo opportunities. Just be sure to pull over safely if you plan to stop.
Pōhakuloa Training Area (PTA)
While you can’t enter the military training area, the PTA adds to the surreal feel of this stretch of road. Its dry, barren terrain makes you feel like you’ve landed on another planet. Keep an eye out for military aircraft or convoys, as they occasionally use the area for training exercises.
Hakalau Forest Reserve & Kaumana Caves
If you’re heading to or from Hilo, consider adding a quick detour to Hakalau Forest Reserve, known for its native birdwatching trails and lush scenery. Or stop by Kaumana Caves, one of the more adventurous lava tubes in Hawaii that you can explore safely with a flashlight and sturdy shoes.
Night Skies Like Nowhere Else
After sunset, Saddle Road truly lives up to its “Highway to the Stars” nickname. Its high elevation, dark skies, and lack of light pollution make it one of the world’s premier spots for stargazing.
The area around Mauna Kea Access Road is particularly popular for night sky viewing. Visitors can often spot constellations, planets, and even the Milky Way with the naked eye. The Mauna Kea Observatories are internationally renowned for astronomical research, and though the summit is off-limits to most visitors after dark, the Visitor Information Station frequently hosts free stargazing events and talks.
Tips for Your Saddle Road Adventure
To make the most of your Saddle Road experience, here are a few practical tips:
Drive During Daylight: The views are best during the day, and it’s safer to navigate the elevation changes, various animals that run across the road, and the curves in daylight.
Fuel Up First: There are no gas stations on Saddle Road itself, so start your journey with a full tank.
Dress in Layers: Temperatures can drop significantly as you climb, and it gets chilly even during the day.
Watch the Weather: Conditions can change quickly, with clouds and fog appearing out of nowhere.
Pull Over Safely: If you want to take photos, only stop in designated areas or safe pullouts.
Cultural Sensitivity: Respecting Mauna Kea
While the summit of Mauna Kea offers breathtaking views, it’s important to understand that this mountain holds deep cultural and spiritual significance for Native Hawaiians. It is considered a sacred place, and many community members continue to advocate for its protection.
If you choose to visit the Mauna Kea Visitor Information Station, please do so respectfully. Stay on designated paths, follow posted guidelines, and avoid disturbing the natural landscape or cultural sites. Learning about the mountain’s significance before your visit can add meaning to your experience and show respect for the people and culture of Hawai‘i.
