Short answer. The Phuket Travel Price Index measures what moves inside the island, so it holds no fare for the run to Krabi or Khao Lak, and this guide does not invent one. What the data does give is a sound baseline: a private minivan from the airport to Mai Khao is $32 per vehicle ($15–55, n = 7), to Nai Yang $29, and to Patong $44 in the October 2026 revision. A mainland run is longer than any of these, so expect a quote well above them, in baht, per vehicle. A hire car is $24 a day on a week-long rental. The practical choice is between five options: a private minivan, a shared van, a scheduled bus, a ferry (Krabi only) and a self-drive car. Khao Lak is reached by road over the Sarasin Bridge, north of the airport; Krabi is reached by road across the mainland or by sea. This guide explains each option, what to ask for, and which months make the sea route unreliable.
What the index can and cannot price
The index is built on a strict rule: a median is published only when at least five independent sources priced the same product, and nothing is estimated from neighbours. That rule has a consequence for this topic. The transfers series covers rides that start at Phuket airport and end in one of fifteen Phuket areas. Nobody in the dataset has measured Phuket to Krabi or Phuket to Khao Lak, so there is no number here, and any article that prints a flat “price to Krabi” for every season is quoting something other than this data.
What can be done honestly is to anchor the decision on three measured things:
- the cost of the island leg, since most mainland journeys begin at the airport or at a Phuket hotel;
- the cost of a car, because a self-drive mainland trip is a rental question;
- the weather and sea state by month, since sea crossings and mountain roads are the two things the season changes.
Everything else, such as a coach timetable or a ferry schedule, changes by operator and by season, and it is described below as a mechanism with a note of how to check it.
The baseline: what a vehicle costs on the island
The transfers series is a useful yardstick because it prices the same product, a private minivan per vehicle, across many areas. Here are the north-coast areas that matter most for this journey, together with two reference points further south.
| Airport to | Minivan, per vehicle | Range across sources | n |
|---|---|---|---|
| Nai Yang | $29 | $15–55 | 5 |
| Mai Khao | $32 | $15–55 | 7 |
| Bang Tao | $45 | $19–67 | 9 |
| Patong | $44 | $21–79 | 11 |
| Rawai | $52 | $42–91 | 7 |
Two readings follow from the table. First, the price of a minivan does not rise in a straight line with distance. Mai Khao is 8 km from the airport and Patong 32 km, yet the wide ranges show that the spread between quotes for the same route is as large as the gap between routes. A transfer price depends on the operator, on the vehicle, and on whether the booking is made before arrival, as much as on the kilometres. Second, a route with fewer than five sources, such as the ones where the index shows only a range, should be read as “somewhere inside this band”, not as a tariff.
For a mainland run the same logic applies, only more so: the same journey is quoted at very different prices by different operators, and the spread is wider than on the island.
Phuket to Khao Lak
Geography. Khao Lak is a strip of beaches in Phang Nga province, on the same Andaman coast, north of Phuket. The only road link is the mainland highway that leaves the island over the Sarasin Bridge in the far north. That is why the north-coast areas are the natural starting point: Nai Yang is 4 km from the airport and Mai Khao is 8 km, so a traveller staying there is already on the right side of the island. From Patong, Kata or Rawai the island leg adds a long drive before the mainland begins.
Options.
- Private minivan or car with a driver. The simplest choice for a family or a group. Agree a fixed baht price per vehicle, state the pick-up address and the drop-off hotel, and ask whether tolls, waiting time and luggage are included. This is the option closest to the island minivan rate in the table above, scaled up for the longer run.
- Airport arrival, direct. If you land at Phuket airport and your hotel is in Khao Lak, the airport is the departure point. You skip the island’s hotels entirely. A pre-booked vehicle waiting in the arrivals hall is the cleanest way to do it; the airport transfer guide explains the arrivals hall, the counters and the traps.
- Scheduled bus or shared van. Cheaper per person, fixed times, and it may stop in several places. It suits one or two travellers with light luggage and a flexible day. Confirm the departure point, because some services leave from the bus terminal in Phuket Town rather than from the beaches.
- Hire car. Sensible if Khao Lak is part of a longer loop and you want a car on the mainland as well. See the section on hire cars below.
Seasonality. Khao Lak is a beach destination on the same open coast as Phuket’s west side, with the same monsoon pattern. The month tokens below show what the climate normals say about the two ends of the year.
| Month | Rain, mm | Rain days | Sea state | Wave height |
|---|---|---|---|---|
| January | 37 mm | 10 | calm | 0.5 m |
| April | 183 mm | 25 | calm | 0.5 m |
| July | 241 mm | 24 | rough | 1.5 m |
| October | 340 mm | 28 | calm | 1.0 m |
These are 2015–2025 normals for the west coast of Phuket from the Open-Meteo reanalysis. They are a guide to the Andaman coast generally, not a measurement of Khao Lak itself, and the data does not claim otherwise. The practical point is that the road is open all year, but in the wettest months a downpour can slow the highway, and the sea at the beach is often too rough to swim. The monsoon season guide covers what that means for a visit.
Phuket to Krabi
Geography. Krabi is a mainland province to the east and south-east. Its main town and its beach resorts (Ao Nang, Railay and others) are reached either by road across the mainland or by sea from the east side of Phuket. The two routes are different products, not two prices for one journey.
By road. The land route uses the same bridge as the Khao Lak route and then turns inland and south. It is a long drive, with the usual options:
- Private minivan door to door, the simplest choice when there are three or more people or a lot of luggage;
- Public bus from Phuket Town’s terminal, cheap and slow, suited to a single traveller;
- Shared van, often booked through a hotel desk, with a pick-up window rather than a fixed time;
- Hire car, for a trip that includes stops.
The transfer between Krabi town and the Krabi beaches is a separate step, and an intercity quote that says “Krabi” without naming the drop-off is ambiguous. Always state the exact resort or hotel.
By sea. A passenger ferry crosses from the Phuket side to Krabi’s coast. It is shorter in road distance but depends on a pier at each end, on timetables that shrink in the green season, and on the sea. Add the island leg to the pier (Phuket Town, Chalong and Rassada are the usual starting points) and the leg from the mainland pier to the hotel. The Phi Phi ferry guide explains how piers, tickets and cancellations work on the neighbouring routes, and the same logic applies here.
The sea matters in a way it does not on the road. Compare the climate normals:
| Month | Sea state | Wave height | Rough-sea days |
|---|---|---|---|
| January | calm | 0.5 m | 0 |
| March | calm | 0.5 m | 0 |
| August | rough | 1.3 m | 9 |
| September | rough | 1.4 m | 12 |
The calmest month in the series is January and the roughest is July. If your plan depends on a ferry connecting with a flight, build in a buffer in the rough months, or switch to the road.
Phuket to Krabi or Khao Lak by hire car
A self-drive trip appeals to families and groups, and it is the only option where the marginal cost of a second stop is nothing. The index prices the rental, not the mainland leg.
An economy automatic costs $24 a day on a week-long rental in the October 2026 revision, with quotes of $15–61 across 7 sources. A scooter is $9 a day, but a scooter on the mainland highway is a poor idea and most insurance does not envisage it. Petrol is 37.01 THB a litre at the pump (latest monthly mean).
Four contract points deserve a check before you set out:
- Island-only clauses. Some rental contracts restrict where the car may go. Ask in writing whether crossing the bridge is permitted.
- Insurance. Basic cover has an excess; read the figure and the exclusions, because a mainland accident far from the desk is slower to resolve.
- One-way hires. A car taken to Krabi is usually returned to Phuket. A drop-off on the mainland is rarely offered, and where it is, it carries a fee.
- Licence. A home licence plus an International Driving Permit is the safe combination. The car rental guide covers deposits, excess and child seats in detail.
For two days of travel, a rental is rarely cheaper than a private minivan. For a week, with a base on the mainland and day trips, it often is. Do the sum with a quote in hand, and use the trip cost tool to see what the rest of the stay adds.

Which option for whom
| Traveller | Best fit | Why |
|---|---|---|
| Couple with a flight to catch | Private minivan | A fixed time, a fixed baht price, door to door |
| Family of four with luggage | Private minivan or hire car | Space, one booking, no changes with children |
| Solo, light bag, flexible | Bus or shared van | Lowest cost per person; accept a fixed schedule |
| Group of six or more | Private minivan, or two vehicles | Price per vehicle falls per head as the party grows |
| Anyone stopping on the way | Hire car | The only option where extra stops cost nothing |
| Diver or island hopper going to the Krabi coast | Ferry plus a short road leg | Skips part of the road, but sea-dependent |
This is a decision aid rather than a ranking. The index does not price these mainland options against each other, so the table is built on mechanism: what each option includes, and where it fails.
How to read a quote
A mainland quote hides more than an island one. Use this checklist:
- Per vehicle or per person? The island figures here are per vehicle for minivans. A shared van is per person. A bus is per person.
- Currency. Operators quote in baht. The dollar figures on this site are conversions at 33.41 THB per USD (ECB, 16 October 2026), so a quote in dollars from a booking platform may include its own spread.
- Drop-off precision. A named hotel and a map pin, not “Krabi” or “Khao Lak”.
- What is included. Tolls, waiting time on a late flight, a child seat, a second stop.
- Pick-up proof. A name board, a contact number and a confirmation message. For a night arrival, a live number matters more than a low price.
- Cancellation. Whether a delayed flight moves the booking or voids it.
If the fare is far below the range you see for the island legs, ask what it leaves out. A very low price usually means a shared vehicle with several stops, a longer wait, or a booking fee added later.
The airport factor
Phuket International Airport carried 17.47 M passengers in 2025, and the busiest month in the series is January 2025 (2.00 M). Peak months matter because queues at the counters grow and the supply of drivers is stretched, which is when last-minute prices are highest and walk-up options are thinnest. A pre-booked vehicle protects you from that. The airport is also the natural start for the north: it sits close to Nai Yang and Mai Khao, and the road north is the way out.
The mainland has its own airport serving Krabi, and many travellers compare it with flying into Phuket and driving. That is a question of a flight price and a ground price, and the index covers only the Phuket side. If you are weighing the two, the Phuket vs Krabi comparison lays out what the data says about the island and where it stops.
When to go, and how to plan the day
Travel in the morning where you can. The wet-season showers described above tend to arrive later in the day, a ferry has more slack in the morning, and a late-afternoon arrival leaves no margin if something runs over. Avoid scheduling a tight connection with a flight on the same day, especially in the rough-sea months. Keep the passport and the hotel address in a place that does not depend on mobile data, and tell the hotel at the other end your expected arrival time so that the front desk is staffed.
For a trip that combines both destinations, the order matters. Khao Lak first and Krabi after means the long leg is spent on the road with the most flexibility, and the ferry (if used) comes at the end, when a delay costs less.
Pitfalls
- “Phuket to Krabi” sold as a fixed price in the street. Treat an offer from someone who approaches you in the arrivals hall as unverified; use a counter, a booked operator, or your hotel.
- A tour office on the way. A commission stop is not part of the fare, and you are not obliged to enter.
- The wrong terminal or pier. Write down the pick-up point and check it against the confirmation. Phuket has several piers and bus stops with similar names.
- Quoting in dollars without a rate. Ask for the baht price; the dollar equivalent is a conversion and changes with the rate (33.41 THB per USD (ECB, 16 October 2026)).
- Assuming the sea is always an option. In the rough months a ferry can be delayed or cancelled. Keep the road as the fallback.
How this guide will stay current
Every figure above is a token that resolves from the index at build time, so the island baseline updates on the 1st and the 15th when the snapshot runs. The part this guide cannot update is the mainland leg, because it is not in the data. When the index adds a measured intercity series, the sections above will be rewritten around it. Until then, treat any mainland fare as a quote to be checked, not a benchmark.
FAQ
How much is a private transfer from Phuket to Krabi?
The Phuket Travel Price Index measures transfers inside the island, not intercity runs, so it publishes no Phuket-to-Krabi fare. The nearest honest baseline is the island’s own minivan rate: $32 from the airport to Mai Khao and $44 to Patong per vehicle (October 2026). An intercity run is longer than any of these, so get a written baht quote, per vehicle, that names the drop-off address.
How long does it take to drive from Phuket to Khao Lak?
Khao Lak lies north of the island, across the Sarasin Bridge, so the drive starts at the airport end of Phuket and is the shortest of the two mainland runs. From Nai Yang (4 km from the airport) or Mai Khao (8 km) it is the natural continuation of the north-coast road. Allow a morning or afternoon rather than a quick hop, and more in a downpour.
Is a hire car a good way to reach Krabi or Khao Lak?
For a family or a group that wants to stop on the way, yes. An economy automatic is $24 a day on a week-long rental ($15–61 across 7 sources, October 2026). Check the rental contract first: some desks forbid taking the car off the island or charge for it, and a one-way drop on the mainland is rarely offered.
Which months are best for the ferry to Krabi?
The calm months. In January the sea state is calm with wave heights near 0.5 m, whereas in August it is rough with 1.3 m waves and 9 rough-sea days on average. Services run in the green season but are cancelled or delayed when the sea is rough.
Can I do Krabi or Khao Lak as a day trip from Phuket?
It is possible, but most of the day is spent on the road. The tour series in the index covers island and bay excursions, not mainland runs, so there is no index price to compare. A one-night stay is usually a better use of the same hours.
Should I book the transfer in advance?
Yes for a private vehicle, a group, a night arrival or a ferry connection: a fixed baht price in writing, per vehicle, with the pick-up point and a contact number removes most of the problems. For a single traveller on a flexible schedule, a scheduled bus or shared van is cheaper and needs no booking beyond a seat.
