|Starting Point||Drive Time (One-Way)|
|Kahului||1.5 - 2 hours|
|Kihei||1.75 - 2.25 hours|
|Kaanapali and Lahaina||2.25 - 2.75 hours|
|Kapalua||2.5 - 3 hours|
|Maalaea||1.75 - 2.25 hours|
|Wailea||2 - 2.5 hours|
1) Head towards Kahului, and get yourself onto the Hana Highway (route 36), driving towards Hana.
2) Make a right turn onto the Haleakala Highway (route 37) - it's a huge intersection with a set of lights, so you can't miss it. Now follow it for almost 8 miles.
3) At the intersection with Haleakala Road, the Haleakala Highway veers left - make a left turn here to follow it. There is a set of lights at this intersection, and a letter "K" on the lawn across from you on the left. Now drive
for another 6 miles.
4) Make a left turn onto Crater Road (route 378) when you see the large brown park sign.
Follow this for about 11 miles until you reach the volcano summit.
On Crater Road, at approximately 7000 feet elevation, you'll see the park entrance booth. You'll be required to show your park entrance pass, or purchase one for $10 (gives you access to Haleakala National Park for 3 days.)

If it gets foggy, there are 2 things you can do that will help you a
ton. First, turn your vehicle's headlights on so oncoming traffic and
cyclists can see you better. Second, don't be afraid to drive slower if
it's unsafe to drive the speed limit.
Fog Avoidance Tip: Avoid the worst of it by aiming to reach the summit earlier in the day. Cloud cover and accompanying fog tend to increase as the day goes on, so the earlier you go, the less fog you are likely to run into.
This is something to watch out for, but it can also be one of the
highlights of your drive. The Hawaiian Nene is an endangered species,
so seeing one of these elusive creatures is a special treat!
These guys usually won't cause you any issues, but, since they have been known to lose control of their bikes once in a while, careening down the road, and sometimes even OFF road, it doesn't hurt to take a couple of easy precautions.
Don't drive too fast in case you need to brake in a hurry, and turn on your headlights so they can see you coming.
We saw lots of police officers out on the road, and there was no shortage of speeders to keep them busy writing tickets. The main ticketing hot spot seemed to be the stretch of Haleakala Highway between the Hana Highway and Makawao. However, we also saw someone getting pulled over by the park rangers across from the visitor center. Keep a close watch on your speed, and you'll be just fine!
There have been rare reports of brake failures on the steep descent from the summit.
So, give your breaks a brake and use low gear on the way down!
Altitude sickness is not likely to affect you on a casual drive to the summit and back. However, if you're planning on spending a longer time up there, (ex. going on a hike in the crater?) you might run into this issue.
Symptoms to watch out for: dizziness, nausea, and headache. If you notice any of these, it may be due to the altitude. If so, the way to fix it is to head for a lower altitude, and drink some water. If symptoms don't resolve, then get checked out by a doctor.
Many people ask this question, and in case you're one of them, I'd like to reassure you. Driving at the lower elevations is no more dangerous than any other major highway, with very good visibility and wide open spaces all around.
The higher elevations sometimes pose some challenges (see above), but if you're careful, you'll stay safe!
The only other thing that you might run into is ice on the roads IF you head to the summit during freezing temperatures. If this happens, just drive very slowly and take your time. Luckily, if you head up there during daylight hours, this is unlikely to affect you.
Layers are great - you can peel off the jackets and sweatshirts if you get too warm!
You should bring along warm clothes for the summit, since temperatures will be quite a bit cooler up there compared to sea level. Daily highs can vary anywhere from 50 - 65F (10 - 18C.) One rule of thumb is to assume it will be about 32F (13C) cooler at the summit compared to down at sea level - but keep in mind that wind and damp weather up there tend to accentuate the cold.
What should you wear? I usually start off my day in shorts and a t-shirt. At the visitor's center, I'll duck into the restroom to change into jeans, plus put on a fleece jacket for the rest of the journey.
If you go to the summit for the sunrise, then dress even warmer since temperatures can dip below freezing at that time of day.
It's a 37 mile drive from sea level to the 10023 foot summit. It's the world's highest elevation gain in the shortest distance.
On the drive to the summit, you'll pass through just as many ecosystems as you would if you drove from Mexico to Canada.
