Cheapest Way to Travel Between Islands in Southeast Asia

A rusty ferry pulling into a pier in the Andaman Sea — the cheapest seat on the boat costs less than a pack of smokes back home.

🎒 Travel style: Ferry-class backpacker — night boats, cheap seats, no checked bags

I woke up face-down on a plastic seat in a 36-seater ferry somewhere between Koh Samui and Koh Tao at 5:15 AM. My neck was twisted sideways. Some guy’s elbow was digging into my ribs. The floor was sticky with something that might have been coconut water or maybe engine oil. The air smelled like diesel and salty sweat. A toddler three rows ahead was screaming. The ferry captain was eating instant noodles at the wheel.

This is how you actually travel between islands in Southeast Asia when you’ve got $32 left in your pocket and five days until your next cash withdrawal at a machine that might or might not eat your card. Not the Instagram version — the real one.

I’ve been doing this circuit for about seven years now, on and off. First time I hit Thailand I was twenty-three, dumb, and carrying a 65-liter pack that weighed more than I did. I bought a plane ticket from Bangkok to Koh Samui because I didn’t know any better. Cost me 3,200 baht. The guy next to me on the minibus to the hostel had taken a night bus and a ferry and paid 780 baht. I wanted to punch him and buy him a beer at the same time.

So here’s the dirt. Here’s how you actually move between Indonesian islands, Thai islands, Philippine islands without burning your budget before lunch.

The Essentials at a Glance

• Ferries are cheaper than flights — every time, in every country, for any island pair under 500 km. The price gap is wider than you think. A flight from Bali to Lombok is $45–$65. The fast ferry is $18. The slow public ferry is $6. Do the math.
• Night ferries save you one night of accommodation — a cabin on an overnight ferry in Indonesia costs $10–$14 and replaces a $7 dorm bed while covering 150 km. That’s a net win.
• Airlines add fees that hit hard — AirAsia and Philippines AirAsia charge for checked bags, seat selection, and even airport check-in sometimes. You can end up paying 60% more than the advertised fare. Ferries include your bag in the seat price.
• Slow ferries aren’t always the best deal — sometimes the “cheap” boat takes 12 hours and you lose a whole day of cheap eating. Time is money when your daily budget is $28.
• The currency trick — if you pay for Indonesian ferries in IDR at the local counter instead of buying online in USD, you save 12–18% instantly. Same for Thai ferries paid in baht at the pier.

Ferry vs Flight: The Real Cost Breakdown

I tracked actual expenses across three countries over two trips — one in 2024, one early 2025. I wrote down every fare, every surcharge, every scam fee a ticket agent tried to tack on. Here’s what the numbers actually look like.

Thailand: The Gulf and Andaman Routes

The Thai island ferry network is the most developed and the most aggressively priced. Take the Bangkok-to-Koh Samui corridor. You can fly direct with Bangkok Airways for 3,200–4,500 baht — they own the route and charge like it. Or you can take a night bus from Khao San Road to Chumphon (500 baht, 7 hours, cold AC that will ruin your spine), then a 5:30 AM Lomprayah ferry to Koh Tao (700 baht, 2.5 hours). Total: 1,200 baht.

That’s roughly $34 USD for the overland route versus $95–$130 for the flight. You save $60+ and you skip the airport taxi scam at Samui — the official taxi line charges 200 baht to get to Lamai Beach from the airport. From the ferry pier it’s 100 baht on a songthaew.

The Koh Phangan Full Moon Party route is even worse for flights. Surat Thani airport to Koh Phangan involves a minibus (250 baht) then a ferry (400 baht) after your flight. Just take the night bus from Bangkok to the pier. You arrive at 6 AM, grab a coffee from the 7-Eleven on the dock, and you’re on the beach by 9:30. Total cost: 780 baht.

Warning — the Lomprayah and Seatran ferries get rough from November to February. I’ve seen people puke into their daypacks. Sit outside on the back deck if you get seasick. Don’t buy the motion sickness pills from the 7-Eleven — they’re 50 baht and they just make you drowsy. Bring your own Bonine from home.

Indonesia: Lombok, Gilis, Flores, and the Lonely Ferry Life

Indonesia is where you can travel for weeks on nothing but ferry decks. The Pelni ships are the backbone of budget travel here — these massive government-run ferries connect almost every major island. A 12-hour Pelni ferry from Bali to Lombok costs 72,000 IDR (about $4.50 USD) for economy class. That’s a steel bench, no AC, a little stall selling fried rice, and a deck full of Indonesian families, chicken cages, and motorbikes strapped to the rails.

Compare that to a flight from Ngurah Rai to Lombok International: $55–$75 with bag fees, plus the taxi to the airport in Bali (200,000 IDR) and the taxi from the Lombok airport to Senggigi (150,000 IDR). The ferry puts you off at Lembar port, which is 20,000 IDR on a local bemo to Mataram.

The Gili Islands are even more lopsided. Fast ferry from Padangbai to Gili Trawangan runs 120,000–180,000 IDR ($7.50–$11) depending on the company — Perama, Gili Getaway, or Blue Water. A flight to Lombok then a speedboat? You’re looking at $85 total. No contest.

But here’s the catch — the Pelni schedule is a joke. Ships run every two to five days on some routes and they leave when they’re full, not when the ticket says. I once waited 14 hours in the port of Labuan Bajo for a Pelni ferry to Sulawesi. Sat on my backpack eating crackers and watching the sun move across the pier. If you’re on a tight timeline, the Pelni system will destroy your itinerary. The fast ferries run daily but cost 4–6x more.

The winner for Indonesia: mix Pelni for long crossings and fast ferries for short hops. Use slow boats for distance, fast boats for logistics.

Philippines: The Archipelago of Overpriced Airfare

The Philippines is the hardest country to island-hop on a budget. The geography is brutal — 7,000 islands spread across a huge stretch of ocean. Ferries exist but they’re slow, infrequent, and sometimes dangerously overloaded. I took a ferry from Cebu to Bohol in 2024 — 2.5 hours, 400 PHP ($7), comfortable AC, on time. Next day I tried to get from Bohol to Siquijor. No direct ferry. Had to go back to Cebu, then across. A three-hour trip turned into nine.

Flights in the Philippines are cheap if you book early but they spike hard at the last minute. Cebu Pacific and Philippines AirAsia run regular sales — I’ve flown Manila to Cebu for 1,200 PHP ($21) booked three weeks out. Same flight booked 48 hours before departure: 4,800 PHP ($85). The ferries don’t spike — they cost the same whether you book today or the day before. A ferry from Cebu to Dumaguete is 650 PHP ($11.50) every single time.

Route that broke me: Puerto Princesa (Palawan) to El Nido. You can take a minibus for 500 PHP ($9) overland, 5–6 hours on winding roads through the mountains. Or you can take the direct ferry for 1,800 PHP ($32), 4 hours, much more comfortable. Or you can fly — but there’s no airport in El Nido. You fly to Puerto Princesa then bus it. So the “cheapest” way is the minibus. I did it. My knees hit the seat in front for six hours. The road is under construction in three separate sections. Dust gets in through the window seals. But I saved 1,300 PHP and spent it on beer and grilled squid that night.

The real hack in the Philippines: combine ferries with overnight buses. The 2GO Travel ferries offer “megadeck” class — a reclining seat on an overnight ship from Manila to Cebu costs 1,200 PHP ($21) and you sleep on board instead of paying for a hostel. Wake up in a new island, no accommodation cost.

Route	Flight (USD)	Fast Ferry (USD)	Slow Ferry (USD)	Savings (flight vs slow ferry)
Bangkok ↔ Koh Samui	$95–130	$28	$21 (bus + ferry)	$74–109
Bali ↔ Lombok	$55–75	$11	$4.50	$50–70
Cebu ↔ Bohol	$35–55	$7	$6 (slow ferry)	$29–49
Manila ↔ Cebu	$21–85	—	$21 (overnight megadeck)	$0–64
Puerto Princesa → El Nido	—	$32	$9 (minibus)	$23 saved (over ferry)

“I spent $72 on a ferry from Bali to Flores because I bought the ticket on 12Go.asia with a credit card. The Indonesian guy next to me paid 185,000 IDR at the dock — that’s $11.50. The markup for convenience was 525%. Never again.”

— The lesson: buy local, pay cash, skip the middleman.

Money-Saving Hacks

These aren’t the “eat local” tips you get from every blog. These are specific, tested tricks that save real money on island transport.

• Buy ferry tickets at the pier, not online. 12Go.asia, Klook, and Booking.com add 15–30% markup on Thai and Indonesian ferries. At the ticket counter in Koh Lanta, the ferry to Koh Lipe costs 950 baht. Online it’s 1,250 baht. The difference is a full day of street food. Same for Indonesia — Pelni tickets bought at the port office cost the government price. Online booking agents add 50,000–100,000 IDR in “service fees.” Show up an hour early, buy at the counter, pocket the difference.
• Carry your own snacks and water. Ferry food is garbage — overpriced instant noodles (60 baht in Thailand vs 14 baht at 7-Eleven) and tiny water bottles (40 baht vs 7 baht). I pack two 1.5-liter bottles from the nearest minimart and a bag of roti or crackers. Saves 100–150 baht per trip. Over 20 ferry rides that’s $60–$90.
• Use the “skip the airport” trick in Indonesia. Flying from Jakarta to Bali is cheap (300,000–500,000 IDR on AirAsia). But the taxi from the airport to Kuta costs 200,000 IDR. Instead fly into Surabaya (often 150,000 IDR cheaper) then take a 6-hour train to Ketapang port and the ferry to Bali (50,000 IDR total). Total saving: $15–$25 and you get a train ride through Java.
• Book Philippine ferries on the 2GO app — the app has “promo fares” that are sometimes 40% cheaper than the walk-up counter price. I booked Cebu to Manila megadeck for 720 PHP during a flash sale. Normal price: 1,250 PHP. Check the app every Wednesday — they run regular deals.
• Negotiate at all small ferry docks — especially in Indonesia. The “official” price board at the Gili Islands ferry dock says 150,000 IDR to Padangbai. But if you walk to the end of the pier and ask a boat captain directly while he’s fixing a rope, you can get 100,000 IDR. They keep the cash, skip the ticket office. Works best in low season (October–March).

Common Budget Mistakes to Avoid

1. Booking a “direct” flight that isn’t direct. I almost bought a “direct” flight from Manila to Coron on Cebu Pacific. Read the fine print: it had a 4-hour layover in Cebu. Total travel time: 9 hours. The ferry plus bus combo takes 10 hours and costs $28 less. The “flight” saved one hour but cost double. Always check the actual travel time, not just the advertised flight time.

2. Paying the “farang price” at Thai ferry counters. The Lomprayah ticket office in Khao San Road quotes 1,200 baht for the bus-ferry combo to Koh Tao. Walk 200 meters to the Thai-owned travel shop next to the laundromat and the same ticket is 950 baht. The difference is literally the commission. Ask at three different shops before buying. Thai friends tell me the standard rate for locals is 850 baht — so if you’re paying more than 950, you’re overpaying.

3. Taking the “cheap” flight that requires a taxi to a secondary airport. AirAsia flies into Lombok’s Praya airport, not the main Lombok International. The taxi from Praya to Kuta Lombok is 350,000 IDR. Main airport to Kuta: 150,000 IDR. The flight to Praya was $8 cheaper. The taxi wiped out the saving and added 30 minutes of driving. Check which airport the budget airline actually flies into.

4. Forgetting that some ferries charge for “luggage” — the fast boats in Thailand will sometimes try to charge 50 baht for a large backpack stored in the cargo hold. I’ve argued this at least four times. They back down if you insist it’s a backpack, not a suitcase. Don’t let them push you. Also don’t put your bag on the seat — they will kick you out of the seat.

Quick Pack & Prep Checklist

Documents & money:

• Passport with at least 6 months validity — photocopies in a separate dry bag
• ATM card with no foreign transaction fee (Charles Schwab, ING, or equivalent)
• $100 USD in small bills as emergency cash — some Indonesian ferries don’t accept cards
• Digital copies of ferry and flight confirmations in Google Drive, not just on your phone

Apps to download before you go:

• 1. 12Go.asia — for quick price checks (don’t buy through it, just compare)
• 2. 2GO Travel app — Philippine ferry flash sales
• 3. Gojek or Grab — for local transport to piers (often cheaper than taxis)
• 4. Maps.me — offline maps for when you’re stuck in a port town with no signal
• 5. XE Currency — for quick math on Indonesian rupiah and Philippine pesos

Niche gear that actually matters:

• Dry bag (10L size) — your backpack will get splashed on small ferries
• Neck pillow that clips — the plastic seats on Thai ferries have no headrest
• Earplugs — the Pelni ferry is loud. Children, karaoke, engines, all at full volume until midnight
• Ziplock bags — for phone, snacks, and wet clothes separately in your pack

Backpacker FAQ

Q: Is it cheaper to fly or take a ferry in Southeast Asia?
A: Ferries are cheaper in almost every case, especially for island pairs under 500 km. A flight from Bali to Lombok costs $55–$75; the public ferry is $4.50. The only exception is very long routes like Manila to Puerto Princesa (1,000+ km) where a 45-minute flight beats a 12-hour ferry for a similar price.

Q: How do I avoid getting scammed at ferry ticket booths?
A: Ask three different booths for the price to your destination. If the first says 1,100 baht and the second says 800 baht, walk. The standard rate is the one listed on the company’s official board — take a photo of it and point when you negotiate. Never pay “VIP fast track” fees for regular ferries. They don’t exist.

Q: Can I book ferry tickets the same day?
A: Yes for most routes. Thai ferries run multiple times daily — show up 45 minutes early. Indonesian Pelni ferries require same-day booking at the port office. Philippine 2GO ferries recommend booking 1–2 days ahead for megadeck class. But walk-up tickets are almost always available. Don’t stress about pre-booking weeks ahead.

Q: What’s the best ferry route for saving money on accommodation?
A: Overnight ferries. The Pelni from Bali to Lombok (economy class, 12 hours, $4.50) and the 2GO megadeck from Manila to Cebu ($21) both replace a night of accommodation. Bring a sleeping bag liner and earplugs. The cabins on long boats cost more. Sleep on deck or in economy class like everyone else.

Q: Are slow ferries safe?
A: The government-run routes (Pelni in Indonesia, 2GO in the Philippines, Lomprayah in Thailand) are safe and well-maintained. Avoid small wooden pump boats in the Philippines if the weather looks bad — I saw two capsized near Coron in 2023. Stick to the big ferries with life vests under the seats and a visible crew. If the boat has a TV playing a movie, it’s a serious ferry. If it’s just a guy and a motor, reconsider.

Final Thoughts

Look, island-hopping in Southeast Asia is one of the cheapest things you can do with your life — if you do it on the water. The flights are a luxury you don’t need. The ferries are part of the experience. You see the coastlines from the water. You meet the same people on multiple boats. You learn the rhythms of each port town — where the good coffee is, which pier has the cheapest nasi goreng, which ferry captain lets you charge your phone in his cabin.

The numbers don’t lie: you can island-hop for 14 days in Thailand and Indonesia on $320–$400 total including ferries, accommodation, and food. That’s a flight ticket cost alone in Europe. The water is the cheap seat. Take it.
