Kahekili Highway

The Kahekili Highway is considered a difficult road ride due to its treacherous nature. It features numerous narrow, single-lane sections, blind curves, steep drop-offs, and a lack of guardrails in many areas. Cyclists should be prepared for significant elevation changes, poor road conditions with crumbling sections and potholes, and one-lane bridges where yielding to oncoming traffic is necessary. Some sections may even require pushing your bike.

Despite its difficulty, the Kahekili Highway offers stunning and unforgettable scenery. You'll experience dramatic coastal views where the rich red earth meets the vibrant blue Pacific Ocean, remote communities, and ranch land. Notable points of interest include Kahekili Highway itself, Honolua Bay, and the powerful Nakalele Blowhole. The landscape varies with green pastures and views of the West Maui Mountains.

Parking options can be limited along the highway, especially in the more challenging sections. For the Waiheʻe end of the route, you would typically look for parking near the Waiheʻe Trailhead or other designated areas. It's advisable to research specific parking availability closer to your planned starting point, as conditions can change.

No, the Kahekili Highway is not suitable for beginner touring cyclists. It is classified as a 'hard road ride' requiring 'very good fitness' and is often referred to as 'the Highway of Death' due to its extreme challenges. Beginners should seek out less demanding routes on Maui.

Cycling on the Kahekili Highway itself, as a public road, generally does not require specific permits or fees. However, if you plan to access any specific trails or areas within the West Maui Forest Reserve, it's always best to check with local authorities or the Hawaii Department of Land and Natural Resources for any current regulations, permits, or entrance fees that might apply to those specific locations.

The best time to cycle the Kahekili Highway is during Maui's drier seasons, typically from April to October. Avoiding the rainy season (November to March) is crucial, as wet conditions can make the already poor road surfaces even more hazardous and increase the risk of landslides. Always check the local weather forecast before you go.

Yes, the Kahekili Highway route does intersect with other paths. Approximately 5% of the route covers sections of the 13 Crossing Trail.

Due to the extremely challenging and dangerous nature of the Kahekili Highway, with narrow roads, steep drop-offs, and lack of guardrails, it is generally not recommended or safe to bring dogs, especially while cycling. The focus should be on rider safety given the conditions.

Given the remote and challenging nature of the highway, you should pack essentials like plenty of water, high-energy snacks, a first-aid kit, sun protection (sunscreen, hat, sunglasses), and appropriate cycling gear. Due to potential lack of cell service, consider a satellite communication device. Be prepared for mechanical issues with a repair kit, spare tubes, and a pump.

No, there is a significant lack of cell service in many areas along the Kahekili Highway. This adds to its remote and adventurous character but also means you should not rely on your phone for navigation or emergencies. Inform someone of your route and expected return time.

An important insider tip for this route is to be extremely cautious of oncoming traffic, especially in the 9-mile section between the Olivine Pools Trailhead and the Waiheʻe Trailhead. This segment is particularly tight with minimal room for passing. Be prepared to yield, and consider starting early in the day to potentially encounter less traffic.
