Look, here’s the thing nobody who writes about this seems willing to say out loud — you can’t actually ferry to Phuket from most places people start a Thailand trip. The peninsula’s in the way. If you’re flying into Bangkok and heading south, the sensible answer is another flight. If you’re coming off Koh Samui and wondering whether there’s a scenic sea route across, there isn’t really one, unless you’ve got 10 hours and a taste for mini-van suffering.

This post is for the one situation where the ferry-or-flight question is actually interesting. You’re already in the southern Andaman. You’ve been on Phi Phi, or Krabi, or one of the Yao islands for a few days, and now you’re working out how to get yourself to Phuket without booking another pointless 30-minute flight. That’s when the boat starts looking good.

I’ll start with when flying is the right answer, because it saves people reading this whole thing if they’re in one of those buckets. From Bangkok, anywhere on the Gulf coast (Samui, Phangan, Tao), anywhere north of Surat Thani, or anywhere abroad, fly. AirAsia and Bangkok Airways run Bangkok-to-Phuket routes multiple times a day, often under 2,000 baht if you book with any lead time at all. The alternatives involve overnight trains to Surat Thani, taxis across to Phun Phin station, buses over the peninsula, and eventually a ferry leg tacked onto the end. People do actually try this, usually for the romance of it. I did it once myself, in 2014, as a bit of a stunt. Took about 32 hours. Would not recommend.

The Samui-to-Phuket routing specifically trips people up. You’ll see travel agents in Chaweng selling a “Samui to Phuket transfer” for around 1,200 baht, which looks like a bargain until you read the small print on what you’ve actually signed up for. Ferry from Nathon to Donsak on the mainland. Bus across to Surat Thani. Minivan across the peninsula via Phun Phin and Khao Sok. And then you roll into Phuket Town about 9 hours later, assuming no breakdowns. The minivan drivers on that route are among the worst in the country for tailgating, and I’ve had three genuinely scary rides on it over the years. Enough that I now fly every time, even when it would be cheaper to suffer the overland.

So that’s the out-of-scope list. What’s left, realistically, is Phi Phi, Krabi, the Yaos, and Koh Lanta. Those are the four starting points where the ferry is genuinely worth thinking about.

The Routes That Actually Run

Phi Phi to Phuket is the one most people end up on. Tonsai Pier on Phi Phi Don across to Rassada Pier in Phuket Town, about 2 hours on the standard slow boats and closer to 90 minutes on the speedboats. Big boats run roughly 450-650 baht depending on the operator and whether you booked through your hotel agent, who usually marks it up 100-150 baht, which is fair enough since they’re running the booking for you. Speedboats are 750-900 and save you half an hour, which isn’t worth much money if you’re not in a hurry. Tigerline, Andaman Wave, and Phi Phi Cruiser are the three operator names you’ll see most often. They pool passengers in high season, so the specific boat you end up on isn’t always the specific company named on your ticket. Don’t worry about this, it’s just how the market works here.

From Krabi town the ferry leaves from Klong Jilad Pier, a 10-minute drive south of the old town. The crossing takes 2 to 2.5 hours, prices sit between 500 and 800 baht, and the boat almost always stops at Phi Phi for about 20 minutes to swap passengers on its way across. Slightly annoying if you’re time-pressed, but it gives you a surprisingly good photo opportunity since the docking angle puts Phi Phi Don’s cliff backdrop right in the frame for 10 minutes. High season you’ve got 2-3 departures a day. Low season, sometimes just one, sometimes none at all if the sea’s doing something unfriendly.

The Koh Yao routes are the shortest and easiest. Various small piers on Yao Yai and Yao Noi across to Bang Rong Pier on Phuket’s northeast coast, in 30 to 45 minutes for around 200 baht. These boats run frequently enough that you don’t really book ahead, and the whole thing feels more like a commuter service than a tourist ferry. Which is what it is. The Yaos are still mostly locals’ islands, and there’s a steady daily flow of people going to and from Phuket for work, shopping, and hospital appointments.

Koh Lanta to Phuket is the longest of the realistic options. It’ll route via Phi Phi nearly every time, so expect 3.5 to 5 hours total with a mid-route connection somewhere in the middle, for somewhere between 900 and 1,200 baht. In low season (late May through October), this route gets thin and sometimes vanishes entirely, so if you’re doing it outside high season don’t rely on the website. Call an agent the day before, or at the very least confirm at your guesthouse the night before you travel.

Why The Pier You Land At Matters

Here’s something most ferry booking sites gloss over and that changes the real cost of your trip significantly. Phuket isn’t a small island. It’s roughly 50 kilometres from the top (where the airport is) to the bottom (Rawai, Nai Harn), with all the touristy beach areas — Patong, Karon, Kata, Surin, Bang Tao — spread along the west coast. Where the ferry drops you determines whether you’re 20 minutes from your hotel or closer to an hour and a half.

Rassada is in the east, just outside Phuket Town. If you’re going to Patong, budget 400-600 baht for a metered taxi and 30-40 minutes of travel time, more if you hit the Patong hill at rush hour. Kata and Karon are slightly further south and cost a bit more, 500-700 baht and roughly 45 minutes. There’s a shared minivan option out of Rassada that costs 150-250 baht per person and looks great on paper until you realise the van is going to drop four other groups at four other hotels before it gets to yours. Usually adds an hour to the trip. I’ve taken it when I had time to kill, and I do not recommend it if you’ve got a dinner reservation.

Bang Rong is an entirely different situation. It’s up near the northeast corner of Phuket, practically adjacent to the airport. If you’re coming in on the Yao route and heading to Patong or Kata, you’re looking at an hour-plus taxi ride and 600-800 baht, which pretty much eats up whatever you saved on the cheap ferry crossing. Where Bang Rong actually makes sense is if you’re catching an onward flight out of Phuket International. From the pier to the airport is 25 minutes and 300-400 baht, which is hard to beat for a connection. I know someone who did the Koh Yao guesthouse to onward flight routing last November and got from her room to her boarding gate in just over two hours total. That’s about as efficient as travel in this country gets.

The naming is the tricky part here, because “Phuket” on a ferry website is a vague concept. Ask your hotel which pier is closer to them before you book, because some booking sites quote the Yao-to-Phuket hop as “just 200 baht” without mentioning you’ll be paying 800 baht for the taxi after.

What The Crossing’s Actually Like

The ferry isn’t as scenic as the marketing photos want you to believe. The interior of the big boats is enclosed, fluorescent-lit, air-conditioned to an actively unpleasant degree, and most people end up dozing or scrolling on their phones for the duration. The deck is where you want to be, specifically the upper deck at the stern, where the captain (if he’s worth anything) has positioned a shade cover. Bring a hat even so. The sun reflecting off open water will burn the back of your neck in half an hour, even when you don’t feel particularly hot.

I took the Phi Phi to Phuket route in early April maybe three years ago, on the 9 a.m. boat, and I remember it as one of the better travel days I had that year, which admittedly is a low bar because most travel days are grim. You pull out of Tonsai slowly because Tonsai Bay is always full of longtails and dive boats and the captain has to navigate around them. Then you curve through the gap between Phi Phi Don and Phi Phi Ley, and for about 10 minutes you’re looking directly at the east side of Phi Phi Ley, which is a view you otherwise only get by paying 2,500 baht for a Maya Bay day tour. Those cliffs are genuinely impressive from the sea, and the fact you see them for free as part of a transit ferry is one of those small travel bonuses the ticket doesn’t bother to mention. After that you’ve got about 90 minutes of open Andaman water with a few tiny rocky outcrops breaking the horizon, and then Phuket’s eastern shore starts creeping into view.

Some practical stuff worth knowing, the kind of thing you figure out the second time but really could have used the first time. Luggage goes in a communal pile at the front of the boat, or sometimes on a rack off to one side. Nobody I know has ever had a bag stolen off one of these ferries. Still, lock your main pack, keep your passport and money in a day bag you hold onto, and don’t have anything valuable hanging off the outside of your luggage where it could walk off easily. The boats have a snack bar where a small water costs 40 baht instead of the 7 you’d pay on land, so fill your bottle before boarding. The toilets technically work but aren’t pleasant, and if you can time your bladder to go before you board, do.

The seat situation on big boats is almost always first-come-first-served, regardless of what an agent told you when they sold the ticket. “Reserved seating” on most of these crossings is a fiction, and the “first-class upgrade” some agents offer for an extra 200 baht usually just means access to the upper deck, which everyone has access to anyway. If an agent is quoting you a premium seat, ask specifically what you’re actually getting, and don’t pay the upgrade unless it’s something concrete like a spot in a dedicated cabin. Those do exist on a couple of boats, but they’re not common.

The April Thing

The original version of this post made a big deal about April, and that part’s actually right. Early April is the best window of the year for any of these crossings. The Andaman monsoon kicks in around mid-May, and before that you’ve got a stretch of calm seas, reliable ferry schedules, and boats that aren’t cancelling because of swell. Once the monsoon properly sets in, the smaller speedboat tours start cancelling routinely, the big ferries keep running but get bumpier, and by July you’ll sometimes see a Phi Phi-to-Phuket crossing that should take 2 hours take closer to 3 because the captain is throttling down through chop.

April mornings are the best slice of that window. Leave Phi Phi at 8 or 9 a.m. and you’re in Phuket by late morning, before the midday heat turns anything you try to do into a slog. The light between 8 and 10 on the water is also the best you’ll get for photos, if that’s a consideration. By afternoon the glare picks up and the sea gets a bit more active as the thermal breeze builds, which isn’t enough to make the crossing unpleasant but is enough that your pictures won’t come out as clean.

The flight from Krabi to Phuket, for comparison, is a 25-minute hop that’s basically unaffected by any of this. You board, you land, and within about 40 minutes of takeoff you’re in an AoT taxi on the way to your hotel. The whole thing blurs together and you won’t remember it a year later, whereas there’s a reasonable chance you’ll remember the ferry ride, which I’d argue is worth something in itself.

So, Boat Or Plane?

The actual answer to the ferry-or-flight question, stripped of the marketing copy: if you’re already in the Andaman (Phi Phi, Krabi, Koh Yao, or Koh Lanta) and you’ve got the time to spend, the boat is genuinely the better move. It’s comparable in total door-to-door time, more pleasant when the weather’s behaving, and you skip the airport part of the trip, which in Krabi’s case means skipping an airport I’ve never once enjoyed passing through. If you’re anywhere else in Thailand, fly. Don’t let anyone sell you a “scenic overland” option from the Gulf side or from Bangkok, because they’re not scenic, just long, and the minivan drivers are the worst part of an otherwise pretty decent country to travel around.
