Maui looks small on a map and does not behave like it. Plan on the clock, not the mileage.
Plan each day around one region. Two is a stretch and three is how a day disappears.
Mauka means the mountain side and makai means the ocean side, and that is how a local will give you directions. On rural routes people navigate by mile marker rather than by street address, so a stop described as being near mile marker 17 is a real instruction and not an approximation.

Use ranges, not map times. The range is the honest number.
Kīhei to Wailea is about 15–25 minutes, and central Kīhei to Wailea specifically runs 15–20 in light traffic and 20–30 around dinner. South Maui to Māʻalaea is about 20–35.
South Maui to West Maui is roughly 45–75. Kāʻanapali to Kapalua is about 15–25. Coming back from Maui Ocean Center in the afternoon, allow 25–40 minutes to Wailea and 35–60 or more to Kāʻanapali — westbound congestion moves that second number quickly.

Kīhei to Makawao is roughly 35–50 and Kīhei to Kula 45–60, with Kula to Ulupalakua another 30–40 without stops.
Two windows do most of the damage, and both are avoidable if you know them.
Southbound Piʻilani Highway backs up on weekdays around the morning commute and school drop-off, roughly 7:15–8:30 a.m., and again from school release into the afternoon commute, roughly 2:30–4:30 p.m. The area around the Kūlanihākoʻi High School roundabout is where it bites. South Kīhei Road is the alternative during those windows; outside them the drive is usually easy unless there is an accident or construction.
On the other side of the island, Hāna Highway slows approaching Pāʻia in the afternoon, particularly on weekdays. Roughly 3–6 p.m. is the window to plan around, as traffic funnels through town and the Baldwin Avenue intersection.
Pāʻia at lunchtime is the one to budget for.
Allow 10–20 minutes to find a legal space and walk, and longer on weekends or strong visitor days. Do not build an itinerary around finding a spot directly in front of the restaurant.

Two stretches of coast are genuinely walkable end to end.
The Wailea Beach Path links the resort beaches and restaurants on a paved coastal route. The Kāʻanapali beach walk does the same on the west side, with a local trolley on top of it. These are the two places to deliberately leave the car parked for a day.
Good for a dinner or an airport run, unreliable as a plan.
Uber, Lyft and the local Holoholo app all operate here, and they are the right answer for a one-way airport trip or a night when nobody wants to drive. Availability thins out late and in the more remote parts of the island, so do not build a remote hiking day around a guaranteed ride back.
Real, cheap, and built for residents getting to work rather than visitors getting to beaches.
The County of Maui runs the Maui Bus fixed-route system. The general one-way fare is $2.00 on all routes, a day pass is $4.00 and a monthly pass with priority boarding is $45.00. Rides are free for passengers 55 and over, students under 25, children 5 and under travelling with a paying passenger, Medicare cardholders and holders of an ADA paratransit or physician-certified disability card — categories that will not cover most visitors.
Twelve fixed routes run islandwide. The ones a visitor is most likely to meet are the Kihei Islander #10, Kihei Villager #15, Lahaina Villager #23, West Maui Express #29, Kula Islander #39, Upcountry Islander #40 and Haiku Islander #35, and the County notes that the Upcountry and Haiku Islander routes stop at Kahului Airport. Separate commuter routes — Haiku-Wailea, Makawao-Kapalua, Wailuku-Kapalua and Kihei-Kapalua — are designed for early morning and evening commuters.
Check the current schedule before you rely on it. We are not quoting frequencies or operating hours because the County pages we read do not publish them in one place.
Build the buffer into the drive, not into your nerves.
For the flight home, add about 30 minutes beyond the normal drive from Wailea and 45–60 from West Maui, on top of whatever the airline asks for. One road incident erases a tight plan, and there is usually only one road.
Allow extra time through Kīhei, the West Maui corridor and Kahului at busy hours. The delay is always at the same three places.
Do not rely on cell service on the Hāna Highway. Download the map before you leave the last town.
Use rideshare for dinner after a long day. A tired driver on a dark rural road is the worst part of any Maui itinerary.
Plan each day around one region. Two regions is a stretch and three is how a day disappears.
Leave South Kīhei Road as your fallback in the commute windows. It is slower per mile and faster overall when Piʻilani is stacked.
Roughly 45–75 minutes, and the top of that range is normal in the afternoon. Westbound congestion moves the number more than distance does.
Roughly 7:15–8:30 a.m. and 2:30–4:30 p.m. on weekdays, worst around the Kūlanihākoʻi High School roundabout. South Kīhei Road is the alternative in those windows.
Yes, at lunchtime especially. Allow 10–20 minutes to find a legal space and walk, and longer at weekends.
The general one-way fixed-route fare is $2.00, a day pass is $4.00 and a monthly pass with priority boarding is $45.00, per the County of Maui.
Wailea and Kāʻanapali. The Wailea Beach Path and the Kāʻanapali beach walk both link beaches, resorts and restaurants on foot.
About 30 minutes beyond the normal drive from Wailea and 45–60 from West Maui, on top of what the airline asks.
