Is Biking Down Haleakala Safe? The Rules, the Risks, and Our Actual Record
Updated July 2026
Short answer: yes, and downhill bike tours on Haleakala are legal and running today. They are not banned. Since February 1, 2023, Maui County has regulated them under Chapter 5.22 of the Maui County Code, which caps group size, sets a minimum rider age of 15, restricts which roads tours may use, and requires guides to ride at the front. Maui Bombers has run this descent for over ten years and more than 1,000 tours.
If you searched "Haleakala bike tours banned" or "Haleakala bike tour suspended" and landed here, you found a real piece of history attached to an out-of-date conclusion.
No, Haleakala Bike Tours Are Not Banned — But One Thing Did Change in 2007
On October 10, 2007, the National Park Service suspended commercial downhill bicycle tours inside Haleakala National Park after a rider fatality. A Board of Review concluded that in-park commercial tours, as they were managed at the time, posed an unacceptably high risk to park visitors. Bike companies kept their authorization to drive guests into the park in a van, but were no longer permitted to launch bicycles inside the boundary.
That moratorium is still in place. It is the origin of nearly every "Haleakala bike tours are banned" result you will find.
What it means in practice today: no commercial bike tour on Maui starts inside Haleakala National Park. Every operator, ours included, begins the ride outside the park boundary. Our descents start at 6,500 feet on Haleakala Ranch land, just below the park entrance.
What Maui County's 2023 Bike Tour Law Actually Requires
The second change came from the county, not the park. The Maui County Council passed Bill 145 (Ordinance 5439), which took effect February 1, 2023 and added Section 5.22.025 to the Maui County Code.
| Rule | What the ordinance requires |
|---|---|
| Minimum rider age | Riders must be over 15 years old — guided and unguided alike. There is no exemption. |
| Group size | No more than 10 riders per guided commercial tour, excluding guides. |
| Guide position | Employee guides must ride at the front of the group. |
| Where you may ride | Haleakala Crater Road between mile markers 3.0 and 9.5 only, sunrise to sunset, seven days a week. |
| Baldwin Avenue | Permitted 8:00 a.m. to 1:30 p.m., and closed to tours on Wednesdays, King Kamehameha Day, Prince Kuhio Day, and La Hoihoi Ea. |
| Roads closed to tours | The rest of Haleakala Crater Road, Haleakala Highway, and Kekaulike Avenue. |
| Enforcement | Police officers and park security may issue citations. Penalties run from $20 to $1,000 and, for some violations, up to 30 days in jail. |
Why the van reappears partway down. The ordinance closes the stretch through Kula to commercial tours. So we ride the first section, load the bikes, drive you through Kula, and put you back on the bikes just past it to finish the descent to Baldwin Beach in Paia.
Why nobody legally offers a bike ride in the dark. Commercial tours may use Crater Road only from sunrise to sunset. A "sunrise bike tour" is a van ride up to watch the sunrise followed by a bike ride that starts after the sun is up. We cover that trade-off in our comparison of sunrise vs. daytime tours.
Why we do not run on Wednesdays. Baldwin Avenue is closed to commercial bike tours every Wednesday, and our descent finishes on it. So we do not operate Wednesdays.
Why we publish 15 and older, plainly. The age floor applies to every tour, guided or not. If you are traveling with kids under 15 who are set on riding, call us before you book — the answer is usually the Upcountry Food Cruise or a different day out.
What Actually Makes a Haleakala Descent Risky
- Speed creep. The grade will accelerate a coasting bike well past a comfortable speed without the rider noticing. Almost every crash on this road is a rider carrying more speed into a corner than they intended.
- Traffic. Crater Road is a two-lane public highway shared with rental cars, tour vans, and commuters, many of whom are looking at the view.
- Cold and wind at elevation. It is roughly 20°F colder at 6,500 feet than at the beach, and cold hands brake badly. This is why we hand out windbreakers, gloves, and rain gear.
- Braking technique. Riders who ride the brakes continuously overheat rims and lose stopping power. Riders who grab the front brake mid-corner go over the bars. Both are fixable in a five-minute briefing.
How a Guided Descent Handles Traffic
On our guided tours, the group does not share the lane with traffic — it occupies it. Matt rides at the front, which the ordinance requires and which we did anyway. A support vehicle follows the group as a rolling block. For roughly 90% of the descent, riders are in the center of the downbound lane.
Traffic is managed on a walkie-talkie. When cars stack up behind the support vehicle, the driver calls it forward. At the next straightaway — chosen for sight lines, not convenience — the group slides right, the driver releases the queue, the cars pass on a straight stretch where everyone can see everyone, and on the all-clear the group retakes the lane.
The rider's job in that system is to ride the bike. You never look over your shoulder and never have to decide when it is safe to be passed.
On unguided tours, that is not how it works, and we will not pretend otherwise. Matt sets riders up at the top and then drives ahead to checkpoints along the route. You ride at your own pace, with traffic, staying right and using bike lanes where they exist. Guests who ride roads in traffic at home tend to love it. Guests whose riding is bike paths and mountain trails are usually happier on the guided tour.
Our Safety Record, in Numbers We Can Stand Behind
We have run this descent for over ten years and more than 1,000 tours.
We are deliberately not quoting you a safety percentage. You will see "99.9% safe" and similar figures on tour sites around the island, and none of them are calculated from anything. A round number with no denominator is a marketing device, not a record.
What we will tell you is how we manage the four risks above, on every single tour: a briefing before anyone rolls, a fleet under three years old serviced by a real bike shop, a guide at the front, a support vehicle holding the lane, and gear that keeps your hands warm enough to brake.
The Equipment We Put You On
- Bikes: Trek Marlin 5 hybrid mountain bikes, every one under three years old. Bought from and serviced by South Maui Bicycles, a real bike shop with certified mechanics.
- Step-through option: Trek Verve, no top bar, more upright riding position — available by request for older guests or anyone with back, hip, or leg limitations.
- Helmets: Specialized.
- Included: windbreaker, gloves, and rain gear, at no extra cost.
Fleet age matters more than brand on a mountain descent, because brakes and cables are what age.
Who Should Not Do This Ride
- Anyone 15 or under. County ordinance, no exceptions.
- Expectant mothers. We would rather not, and we will tell you so.
- Anyone who cannot ride a bicycle. This is not the place to learn.
Beyond that, there is no fitness requirement. It is a descent — you are not pedaling up anything.
Rain, Weather, and When We Cancel
Rain on part of the descent is normal on this mountain and is not a reason to cancel — you have rain gear, and the road is fine. What cancels a tour is an island-wide storm system. In that case we reschedule you, and if we cannot find a date that works before you leave, you get a full refund.
Frequently Asked Questions
Are Haleakala bike tours banned?
No. Commercial downhill bike tours are legal on Maui and running daily. What is banned, since October 2007, is launching a commercial bike tour inside Haleakala National Park.
Can you still bike down Haleakala in 2026?
Yes. Tours operate under Chapter 5.22 of the Maui County Code, in effect since February 1, 2023.
Have there been deaths on Haleakala bike tours?
Yes — fatal crashes in the 2000s are what prompted the National Park Service to suspend in-park commercial tours in October 2007. The rules that govern the ride today exist because of that history.
What is the minimum age for a Haleakala bike tour?
15. Maui County requires riders to be over 15 on both guided and unguided commercial tours.
Do Haleakala bike tours run every day?
Not on Baldwin Avenue. Maui County closes it to commercial bicycle tours on Wednesdays, King Kamehameha Day, Prince Kuhio Day, and La Hoihoi Ea. Our descent finishes on Baldwin Avenue, so we do not run tours on Wednesdays.
How big are the groups?
County law caps guided tours at 10 riders. Our regular tours are capped at 10, our private tours at 5–6, and our average group is about 5.
Do you have to be fit or an experienced cyclist?
No. It is a downhill ride. Casual riders do it comfortably.
Is guided or unguided safer?
Guided. On a guided descent the group holds the lane behind a rolling block and never manages traffic. On an unguided descent you ride with traffic at your own pace, with a support vehicle waiting ahead at checkpoints.
