Big Island of Hawaii Scenic Route

Hamakua Coast Must Drive

The Big Island of Hawaii is known for its dramatic landscapes, lush rainforests, and stunning coastal views. One of the best ways to experience its natural beauty is by taking the Onomea Scenic Drive, a short but breathtaking four-mile route along the Hamakua Coast. This drive, located just north of Hilo, winds through dense tropical foliage, historic bridges, and offers spectacular glimpses of the Pacific Ocean.

Whether you're a nature lover, a photographer, or simply someone looking for a peaceful escape, this scenic detour off Hawaii Belt Road (Highway 19) is a must-visit.

How to Access the Onomea Scenic Drive

If you're traveling north from Hilo on Highway 19, you'll notice a "Scenic Drive" sign near mile marker 7. While you can enter here, the best way to experience the drive is by starting just after mile marker 11, where the road diverges from the main highway.

This picturesque route runs parallel to Highway 19 and eventually rejoins it, making it a short but unforgettable detour that immerses you in Hawaii's breathtaking natural beauty.

What to Expect on the Scenic Drive

The Onomea Scenic Drive is packed with stunning sights, offering a mix of tropical jungle, historic bridges, and ocean views. Here’s what you’ll encounter along the way:

Lush Tropical Vegetation

As you enter the drive, you’ll find yourself surrounded by a dense canopy of towering hala trees, jungle ferns, and vibrant African violets that sometimes spill onto the roadway. The road is narrow and winding, adding to the adventure as you pass through tunnels of greenery.

Historic One-Lane Bridges

Several rustic one-lane bridges cross over small streams and ravines, each offering a unique landscape perspective. Take your time crossing these charming structures and admire the flowing waters below.

Onomea Bay Overlooks

About a mile into the drive, breaks in the vegetation reveal stunning views of Onomea Bay. This secluded bay, once a bustling fishing village, is now a peaceful and scenic spot, perfect for capturing postcard-worthy photos.

Why Visit? This short but rewarding trail takes you down to Onomea Bay, where you can experience the rugged coastline up close. The bay's rocky shore and lush surroundings create a peaceful and secluded atmosphere.

Helpful Travel Tips
  • Bring Insect Repellent: The humid environment attracts mosquitoes, so bug spray is highly recommended.
  • Drive with Caution: The road is narrow and winding, with blind curves and one-lane bridges. Drive slowly and be prepared to yield to oncoming traffic.
  • Respect Private Property: Some areas along the route are privately owned—always follow signage and avoid trespassing.

Why You Shouldn’t Miss This Drive

The Onomea Scenic Drive is more than just a road—it’s an experience that allows you to connect with Hawaii’s breathtaking landscapes at a slower, more intimate pace. Whether you're stopping for photos, exploring tropical gardens, or simply enjoying the lush jungle scenery, this short drive is one of the most rewarding detours on the Big Island.

If traveling along the Hamakua Coast, take this scenic route—a slice of paradise you won’t want to miss.
