Kahekili Highway: How to Drive Maui’s Most Thrilling Coastal Road
The Kahekili Highway (Hawaii Route 340) winds along the remote northern coastline of West Maui, offering one of the most scenic—and heart-pounding—drives in all of Hawaii. This narrow, twisting road hugs cliffs that drop dramatically into the Pacific, passing through lush valleys, sea-sprayed lookouts, and tiny rural communities. Driving it is not for the faint of heart, but for travelers who come prepared, it’s an unforgettable adventure filled with breathtaking views and a true taste of wild Maui. In this guide, we share everything you need to know about tackling the Kahekili Highway safely, including driving tips, must-see stops, and what to expect along the way.

What is Kahekili Highway?
Picture a one-lane road clinging to cliffs, twisting through blind corners, steep drops, and hairpin turns — with nothing but open ocean hundreds of feet below. That’s Kahekili Highway, also known as Hawaii Route 340, one of the most thrilling and challenging drives in the United States.
This rugged coastal route traces the northern edge of West Maui, connecting Wailuku with Kapalua through a landscape few visitors ever see. It’s wild, remote, and absolutely breathtaking — a true hidden gem for adventurous travelers.
Locals sometimes call it the “Death Highway” because of its narrow lanes, lack of guardrails, and sharp drop-offs. While that nickname might sound dramatic, it’s a reminder that this road demands respect and caution. It’s not a drive for beginners, large vehicles, or those prone to motion sickness.
Chris and I tackled the Kahekili Highway in a Jeep Wrangler, which was the perfect choice for its tight curves and uneven pavement. With more than 35 years of driving experience, Chris handled it confidently — but even with our background in remote and off-road travel, we treated this drive with care.
Unlike the famous Road to Hana, which is busy and well-traveled, Kahekili Highway remains quiet, raw, and authentic. You’ll pass dramatic sea cliffs, ancient lava formations, tiny local villages, and hidden lookouts few tourists ever reach.
If you plan to experience this adventure, we strongly recommend driving clockwise (from west to east) — from Kapalua toward Wailuku. This direction keeps you on the mountain side, not the cliff edge, and follows the same flow as most local traffic.
It’s not for everyone — but for confident, experienced drivers who love scenic challenges, Kahekili Highway offers a glimpse of “old Maui” that’s every bit as magical as the Road to Hana, just wilder and far less crowded.
Kahekili Highway Map and Driving Route Overview
The Kahekili Highway (Hawaii Route 340) is one of Maui’s most scenic — and most challenging — roads. This 30-mile stretch hugs the remote northern coastline of West Maui, running between Kapalua and Wailuku. The route is carved into cliffs that drop dramatically toward the ocean, offering nonstop views of the Pacific, lava formations, and lush green valleys.
Named after King Kahekili, the last ruling chief of Maui, this highway is not for the faint of heart. It’s narrow, full of blind turns, and often just one lane shared by traffic going both directions. Yet for those who come prepared, it rewards with unforgettable views and a true taste of wild Hawaii.
Driving Route Breakdown
While the entire stretch is often referred to as the Kahekili Highway, the drive can be divided into three distinct parts:
1. Kahului to Kapalua (Highway 30)
The first section, starting from Kahului and continuing west toward Kapalua, is an easy and well-paved drive along the Honoapiilani Highway (Route 30). It’s wide, safe, and offers great coastal views — perfect for warming up before the narrow section begins.
2. Kapalua to Waihee (Highway 340 – The True Kahekili Highway)
Beyond Kapalua, the smooth pavement narrows into a twisting, cliff-hugging one-lane road — the official Kahekili Highway (Route 340). This is the section that earns its reputation. Between mile markers 6.9 and 16.3, the state-maintained road transitions to county maintenance, and the pavement becomes rougher with tighter curves.
This 10-mile segment is where you’ll experience the real thrill — sheer cliffs on one side, rock walls on the other, and only enough room for one vehicle at a time in some places.
3. Waihee to Wailuku
After Waihee Point Lookout, the road gradually widens and smooths out again as you reenter residential areas. The Kahekili Highway officially ends near Waiehu Beach Park in Wailuku, where you can relax and reflect on completing one of Maui’s most exhilarating drives.
Route Direction: Clockwise or Counterclockwise?
We strongly recommend driving clockwise, from Lahaina or Kapalua toward Wailuku. This keeps you on the mountain side rather than the exposed cliff edge and makes it easier to pull over safely when yielding to oncoming vehicles.
You’ll also be traveling in the same direction as most local traffic, which helps reduce stress on one-lane sections.
Distance and Driving Time
- Distance: ~36 miles (58 km)
- Drive time (nonstop): About 2 hours
- Recommended time (with stops): Plan at least 4–5 hours to enjoy the views, hikes, and small local stops.
This drive is slow and requires full attention — expect to average only 10–15 mph in many parts. Take your time, enjoy the scenery, and remember: this is not a route to rush.
Navigation and Connectivity Tips
- Download Offline Maps: Cell service is limited or nonexistent along much of the route. Use Google Maps or Maps.me offline before you leave populated areas.
- No Gas Stations: Fill your tank in Lahaina, Kapalua, or Wailuku before starting the drive.
- Start Early: Aim to begin by mid-morning so you have plenty of daylight for stops and photos. Never attempt this road after dark — there are no streetlights or guardrails.
- Respect the Locals: This is not just a tourist road — it’s also used by residents who know every curve. Drive courteously, pull over when safe to let them pass, and never block the lane to take photos.
What to Expect on the Drive
Driving the Kahekili Highway is unlike any other experience in Maui — or anywhere in the U.S. This road delivers jaw-dropping beauty and heart-pounding moments in equal measure. It’s one of those drives where every mile feels like an adventure, but it also demands your full attention.
Road Conditions
The Kahekili Highway is fully paved, but don’t expect smooth asphalt or wide lanes. The pavement often narrows to a single lane shared by two-way traffic, with steep drop-offs on one side and rock walls on the other.
There are no guardrails, few pullouts, and limited visibility around blind corners. Some sections are uneven or patched, especially in the county-maintained middle stretch between mile markers 6.9 and 16.3.
Even though it’s paved, this is not a casual scenic drive — it’s a remote coastal road that rewards patience and caution. Speeds rarely exceed 15 mph, and you’ll often need to pull over to let oncoming vehicles pass.
Traffic and Local Etiquette
Traffic on Kahekili Highway is light, but the few vehicles you’ll meet are often locals who drive this road daily. Many residents commute between small coastal villages, so they know the route well.
If someone approaches from behind, pull over safely and let them pass. Avoid stopping in the middle of the lane to take photos — it can block traffic and create dangerous situations.
Honk gently before blind corners to alert oncoming drivers — a common and courteous local practice.
No Service and No Services
Don’t expect to find cell service, gas stations, or food stops along the middle stretch of the route. This part of Maui is wild and isolated.
Before you start, make sure to:
- Fill your gas tank in Lahaina, Kapalua, or Wailuku.
- Download offline maps, as GPS often cuts out.
- Bring water, snacks, and a fully charged phone for safety.
This drive is all about self-sufficiency. There are no stores or restrooms until you reach the other side.
Weather and Road Safety
Weather on West Maui’s north coast can change quickly. Sunshine can turn into rain and fog within minutes, making the road slippery. Landslides and falling rocks are also possible after heavy rain.
Always check the Maui road conditions and weather forecast before you go. If the forecast calls for heavy rain or strong winds, postpone your trip — visibility can drop dramatically, and the road becomes much riskier.
Not for Everyone
If you’re uncomfortable with heights, get carsick easily, or have limited driving experience, this road may not be for you. The Kahekili Highway is safe for confident, alert, and patient drivers — but it can be nerve-wracking for others.
That said, with proper preparation, caution, and respect for local traffic, thousands of visitors drive it safely every year.
The Reward
Despite its reputation, this drive is unforgettable. You’ll see untouched Maui landscapes that few tourists ever reach — rugged cliffs, remote bays, ancient lava fields, and waves crashing against black volcanic rock.
It’s not just a drive — it’s an experience that captures the essence of old Hawaii: raw, natural, and breathtaking.
What to Wear for the Drive
Dress comfortably for this adventure. Wear sturdy, waterproof shoes with good traction—not flip-flops. Some viewpoints and attractions require short walks over wet or uneven rocks, and the ground can be slick from ocean spray. Good shoes with grip will keep you safe and let you explore comfortably.
Best Scenic Stops on the Kahekili Highway
The Kahekili Highway isn’t just about the thrill of the drive — it’s also packed with incredible viewpoints, hidden beaches, and local treasures. From rugged lava formations to charming coastal villages, each stop offers something unique. Here are the most unforgettable places to visit along this wild and scenic road.
Honokohau Bay & Makaluapuna Point (Dragon’s Teeth)
Your Kahekili Highway adventure begins at Honokohau Bay, right where the Honoapiilani Highway (Route 30) ends and Route 340 — the true Kahekili Highway — begins. This peaceful cove is framed by lush cliffs and turquoise water, a perfect first stop before the narrow, winding section starts.
Just a few minutes away, hike to Makaluapuna Point, also known as Dragon’s Teeth, located near Kapalua. Sharp lava formations shaped by centuries of crashing waves resemble the jagged mouth of a dragon — an incredible sight and a photographer’s dream.
The area is also home to the Honokahua Burial Site, an ancient Hawaiian burial ground. Nearby, you’ll find a white coral labyrinth, known as the Dragon’s Teeth Labyrinth, created in 2005 as a peace project. Walking its spiraling path offers a moment of reflection amid the wild beauty of the coastline.
Honolua Bay and Honolua Forest Trail
A few miles north, stop at Honolua Bay, part of the Marine Life Conservation District and one of Maui’s best snorkeling spots. Fishing and collecting rocks or shells are strictly prohibited here to protect the fragile ecosystem.
To reach the beach, walk through Honolua Forest, a lush, shaded jungle alive with vines and birdsong. It’s an easy 10-minute trail that feels like stepping into another world.
If you plan to snorkel, bring a snorkel set, reef-safe sunscreen, and a quick-drying towel — and enjoy some of the clearest underwater views on Maui.
Nakalele Blowhole
Around mile marker 38, you’ll find one of the Kahekili Highway’s most dramatic natural wonders — the Nakalele Blowhole. When waves crash into the lava shelf below, air and seawater shoot up through a natural hole in the rock, creating a powerful geyser that can reach up to 100 feet high.
Safety Tip: Stay well back from the edge. The rocks are extremely slippery, and sneaker waves can appear suddenly. Keep a safe distance and protect your camera gear — the ocean spray is strong here.
Ohai Loop Trail
Between mile markers 40 and 41, pull over for the Ohai Loop Trail, one of the best short hikes on Maui’s north coast.
This 0.6-mile (1 km) loop follows gentle hills above the cliffs, offering panoramic ocean views and colorful wildflowers. The trail is named after the native ‘Ohai plant, which you’ll see blooming along the path.
It’s an ideal stop to stretch your legs, breathe in the sea air, and spot whales in winter — so don’t forget binoculars!
Olivine Pools Trail
A little farther along, look for the sign to the Olivine Pools, natural tide pools formed in volcanic rock. They look inviting, but do not swim here — rogue waves have swept visitors away, and several fatalities have occurred.
Instead, enjoy the short but steep hike for its stunning views of the cliffs and ocean. You’ll find a memorial near the path honoring those lost to the sea, a solemn reminder to respect Maui’s wild forces.
Kahakuloa Village
Nestled between mile markers 14 and 15, Kahakuloa Village is one of Maui’s most isolated and picturesque communities. Home to around 100 residents, it feels like stepping back in time.
Stop here to rest, chat with locals, and enjoy the island’s best banana bread — choose between Julia’s Banana Bread or Lorraine’s Banana Bread and Cream Pie. You’ll also find Karen Lei’s Gallery, Bruce Turnbull’s Sculpture Studio, and other small artist shops. Supporting these local businesses helps sustain this unique community.
Ranch Lands and Pastures
As you leave Kahakuloa, the landscape opens into rolling green hills dotted with grazing cattle. This stretch of road feels peaceful after the narrow cliff sections. The views are wide and open — a striking contrast to the rugged coastline you’ve just conquered.
Kahakuloa Head (Kahekili’s Leap)
Near the village stands the striking Kahakuloa Head (Pu‘u Koa‘e) — a 636-foot (194 m) cliff that legend says was King Kahekili’s favorite cliff-jumping spot.
Kahekili, the fearless Maui ruler for whom the highway is named, was said to leap from this promontory into the ocean below as a test of courage — a tradition later echoed at Black Rock in Ka‘anapali.
You can see the headland from several roadside pullouts — it’s one of the most dramatic views along the highway.
Local Fruit Stands and Artists
Before you reach Waihee, the final stretch of the Kahekili Highway flattens out and widens. Along the way, you’ll find roadside fruit stands and local art stalls.
Stop for a fresh coconut, pineapple, or smoothie, chat with vendors, and take a break after the adrenaline-filled drive. It’s a great way to end the journey while supporting small Maui businesses.
Final Thoughts on Driving the Kahekili Highway
The Kahekili Highway isn’t for everyone — but for those ready for adventure, it’s one of Maui’s most unforgettable drives. This rugged coastal road offers raw, untouched beauty that feels worlds away from the island’s resorts.
If you plan ahead, drive slowly, and stay alert, the journey rewards you with views few visitors ever see: windswept cliffs, remote bays, and the deep-blue Pacific crashing far below. It’s not just a road trip — it’s a glimpse into the wild heart of Maui.
When you finish, you’ll understand why locals speak of Kahekili with both respect and awe. It’s a drive that stays with you long after you return home — one that reminds you why you fell in love with Hawaii in the first place.
