Nakalele blowhole, Hana and roads

Question

Hi! We are going to be in Maui early September. We love hiking and beauty but not dangerous driving. We are planning to walk the Kapalua Coastal trail and have seen that just a little further is the Nakalele Blowhole , but I have also read horror stories about Route 30/340/Kahekili Highway and definitely don’t want to deal with the dangerous part of that road. My question is about where does the road become dangerous and is there clear marking of the road so we don’t accidentally get on and have no way of turning around?

Also is the entire Road to Hana curvy with blind spots and drop offs? I would LOVE to hike the Pipiwai trail and see the black sand beach but I do not think my nervous system will handle much if any of the Road to Hana and wondered if here are a few stops early on the Road to Hana that would be before it gets more intense/scarey so we could just get a taste of it? I hate to miss beautiful things but don’t want to dread the anxiety of the drive. Thank you so much!

Answer

Maui’s northwest coastline is beautiful but has some stretches that are narrow, winding, and cliffside, which can be stressful for drivers who aren’t comfortable with sharp turns and limited guardrails. Here’s a breakdown to help you plan safely.

Nakalele Blowhole and Kahekili Highway (Route 340):

The blowhole itself is accessible via the Kapalua Coastal Trail area and a short walk, so visiting it doesn’t require driving the full dangerous stretches. The more challenging part of Route 340 (Kahekili Highway) begins past Kapalua and continues north along the coast toward Wainee and Honolua Bay. This section has narrow lanes, sharp switchbacks, and few guardrails, with blind corners in several places.

The dangerous stretches are generally after Kapalua, especially approaching Honolua Bay and continuing past the Kahakuloa Village turnoff.
Signage: There are warning signs indicating narrow roads, one-lane bridges, and sharp curves, but the road is not always forgiving. It’s possible to turn around in some spots, but there are long stretches where it might feel committed until you reach a wider area.
Tip: If you prefer to avoid anxiety, you can visit Nakalele Blowhole from the Kapalua side without venturing far on Kahekili Highway. Many visitors hike the coastal trail and reach the blowhole safely, then return the same way.

Road to Hana (Route 360):

This legendary road is scenic but challenging in parts. The early stretches are paved, relatively wide, and less stressful, but as you move further east, the road narrows, has more curves, blind spots, and one-lane bridges. It becomes more intense after Paia town and especially past mile marker 14–15.

Early stops that are less stressful include Twin Falls, Garden of Eden, and Ho’okipa Beach. These are accessible before the road becomes extremely winding and narrow.
The Pipiwai Trail and Waimoku Falls (near Ohe’o Gulch/Kipahulu) are farther along, past mile marker 40. Driving there requires navigating many one-lane bridges, cliffside turns, and hairpin curves, which can be nerve-wracking if you’re anxious about driving.
Alternative: Consider booking a guided tour from the Kahului area. Many tour operators offer transportation to Pipiwai Trail and the black sand beach at Wai’anapanapa State Park, allowing you to experience the beauty without handling the challenging drive yourself.

Summary:

For Nakalele Blowhole, stick to the Kapalua Coastal Trail approach to avoid the narrowest parts of Kahekili Highway.
If you want a taste of the Road to Hana without anxiety, focus on the first 15–20 miles east of Paia. This includes waterfalls, gardens, and beaches before the road gets extreme.
For full Hana experiences like Pipiwai Trail, black sand beach, and Ohe’o Gulch, consider a guided tour or shuttle service to avoid the most stressful driving.

By planning this way, you can enjoy stunning Maui scenery and hikes without spending the day in a high-stress driving situation.
