Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Cheapest island of the three | Koh Tao | Dorm from ₹861 (~300 THB or ~$8.94) |
| Best Full Moon Party | Koh Phangan | Entry ₹1,723 (~600 THB or ~$17.87) |
| Easiest to reach from Bangkok | Koh Samui (direct flight) | Flight from ₹10,050 (~3,500 THB or ~$104.25) |

Subodh’s Pro Tip: All three islands use the Thai baht. At current rates (1 THB ≈ ₹2.87), a 300 THB dorm costs roughly ₹860. Don’t exchange at the airport: the Surat Thani or Koh Samui airport counters take a 15-20% spread.

Safety Alert: All three islands have had reports of scooter rental scams (pre-existing damage charged on return). Photograph the bike from every angle before riding off, and use a helmet. On Koh Phangan Full Moon nights, pickpocketing spikes around Haad Rin and on the ₹287 (~100 THB or ~$2.98) songthaew back to the pier. Wear a money belt.

Choose Koh Samui If…
- You want a direct flight from Bangkok or Chiang Mai. Bangkok Airways flies Bangkok to Koh Samui (USM) from around ₹10,050 (~3,500 THB or ~$104.25) one way, and it’s a 20-minute drive to Chaweng after landing. The other two islands require a bus or ferry connection.
- You need Indian food reliably. Chaweng has at least six Indian restaurants with proper thalis, including Giant Summit Restaurant, which has mountain views and a marked-veg menu, and Zazen, which blends Thai and Indian flavours.
- You’re on a short trip (3-4 nights) and don’t want to lose a day to ferry connections. Koh Samui’s airport saves 4-5 hours each way.
- You want hospital-level medical care on the island. Bangkok Hospital Samui is a private facility that takes travel insurance direct billing, useful if you take a bad scooter turn. You may also find Phuket vs Krabi Which One Should You Actually Pick useful for this trip.
Choose Koh Phangan If…
- The Full Moon Party is the reason you’re coming to Thailand in the first place. Tickets cost ₹1,723 (~600 THB or ~$17.87) at the door on Haad Rin Beach, and the monthly schedule is posted two months ahead. Half Moon and Black Moon events (smaller, slightly less crowded) run ₹861 (~300 THB or ~$8.94) on the party’s official site.
- You want yoga + party in the same week. The north of the island (Sri Thanu, Chaloklum) has 30+ drop-in yoga studios at ₹1,149 (~400 THB or ~$11.91) per class, and you’re 30 minutes by scooter from the south’s party strip when you want noise.
- You’re a digital nomad who wants to slow down but not disappear. Koh Phangan has 50+ co-working spaces and a year-round community in Sri Thanu, with monthly rentals from ₹22,972 (~8,000 THB or ~$238.29).
- You want to combine with Koh Tao for the “two islands in one trip” move (see the Combined section below).
Choose Koh Tao If…
- Open Water certification is the goal. Koh Tao has the lowest PADI Open Water course prices in Thailand, from ₹28,141 (~9,800 THB or ~$291.90) including 4 nights’ dorm accommodation at the dive school. The same cert in Koh Samui or Koh Phangan costs ₹33,022-₹37,330 (~11,500-13,000 THB or ~$342.54-$387.22).
- You want the cheapest dorm bed of the three islands. Fan dorms in Sairee run ₹861 (~300 THB or ~$8.94), and AC dorms ₹1,436 (~500 THB or ~$14.89). Phangan’s equivalent is ₹1,292-₹1,723 (~450-600 THB or ~$13.40-$17.87), and Samui’s ₹1,723-₹2,584 (~600-900 THB or ~$17.87-$26.81).
- Snorkelling and beach time are your main activities. Koh Tao is small enough to walk across in 3 hours, and the snorkel spots at Mango Bay, Shark Bay, and Aow Leuk are reachable by ₹287 (~100 THB or ~$2.98) longtail boat from Sairee.
- You’re okay with one Indian restaurant on the whole island and mostly local food for 4-5 nights. Travellers report that veg options exist but require planning.
Koh Samui: Pros and Cons
Pros:
- Bangkok Airways direct flights from Bangkok (₹10,050 (~3,500 THB or ~$104.25)), Chiang Mai (₹12,922 (~4,500 THB or ~$134.04)), and Phuket (₹10,912 (~3,800 THB or ~$113.19)), no ferry needed
- Six-plus Indian restaurants in Chaweng, plus a real mall (Central Festival) with a food court and a Boots pharmacy
- Hospital-quality medical care, useful if you take a bad scooter turn or get a dive injury
- Best beach variety for non-divers: Chaweng (party), Lamai (mid-range), Choeng Mon (quiet)
Cons:
- Most expensive island of the three for accommodation, food, and transport
- Day-trip boats to Ang Thong Marine Park cost ₹4,307-₹7,179 (~1,500-2,500 THB or ~$44.68-$74.47), almost double what you’d pay from Koh Phangan
- The beaches near Chaweng feel developed, with concrete beachfronts and busy roads. Head to the south or west coast for quieter sand
- Scooter rental is the only realistic transport option outside Chaweng, and the hills are steep if you’re not used to them
Koh Phangan: Pros and Cons
Pros:
- Best party-to-yoga balance of the three, with a clear north/south split
- Cheaper than Koh Samui across dorms, food, and scooter rental
- Easy ferry from Koh Tao (1 hour 30 minutes, ₹1,149 (~400 THB or ~$11.91)) and Koh Samui (30 minutes, ₹574 (~200 THB or ~$5.96))
- Bottle Beach, accessible only by longtail boat, is one of the best unspoiled beaches on the Gulf coast
Cons:
- Full Moon nights see pickpocketing, drug pushers, and songthaew overcrowding. Avoid the Haad Rin backpacker strip if you don’t want chaos
- October and November are real wet season; some ferries cancel, and the Full Moon gets cancelled outright if the sea is too rough
- Limited Indian food outside Sri Thanu; veg travellers need to plan ahead
- Better to stay 5+ nights. The ferry connection eats a day, and the island is too big to rush
Koh Tao: Pros and Cons
Pros:
- Cheapest island of the three across the board: dorms from ₹861 (~300 THB or ~$8.94), local food from ₹172 (~60 THB or ~$1.79), scooter rental from 200 THB/day
- Best dive training in Southeast Asia. Open Water course from ₹28,141 (~9,800 THB or ~$291.90), Advanced from ₹24,408 (~8,500 THB or ~$253.18), with dozens of dive schools concentrated in Sairee
- The smallest island: 21 km². You can walk across it in half a day, and the snorkelling at Mango Bay, Shark Bay, and Japanese Gardens is reachable by short longtail rides
Cons:
- Limited Indian food: only one or two proper Indian restaurants, and most backpackers fall back on local Thai + Italian. Veg travellers should expect to eat the same Thai veg dishes (pad pak, tofu pad Thai, tom yum with mushrooms) for 4-5 nights
- Wettest of the three islands because of the mountain in the middle. Koh Tao catches rain even in the dry months
- Hospital is small. Serious medical issues require a ferry to Koh Samui’s Bangkok Hospital
- Visa runs and onward transport are slower. Most travellers leave by sleeper train to Bangkok (12 hours including ferry)

What to Eat on Each Island
Each island has a real food scene if you know where to look. Use the local spots below for Thai food, and the Indian restaurants for a dal-chawal reset.
Koh Samui (local): Clandestino Koh Samui is a chic restaurant in Bophut with a modern Thai-European menu, mains ₹1,005-₹1,579 (~350-550 THB or ~$10.43-$16.38). Penne Vegan Restaurant Samui is a cozy vegan spot, fully plant-based, mains ₹517-₹804 (~180-280 THB or ~$5.36-$8.34).
Koh Phangan (local): Sri Thanu night market runs Wednesdays and has mango sticky rice from ₹172 (~60 THB or ~$1.79) and pad Thai from ₹230 (~80 THB or ~$2.38). Chaloklum fish market in the morning sells grilled catch from ₹345 (~120 THB or ~$3.57) per plate.
Koh Tao (local): Sairee beach road has 30+ open-air restaurants. Look for khao soi-style coconut curries (₹345 (~120 THB or ~$3.57)) and grilled fish with som tam (₹431 (~150 THB or ~$4.47)). The Italian cafes around Mae Haad do wood-fired pizza from ₹718 (~250 THB or ~$7.45).
For Indian food: Koh Samui is the easy win, with Giant Summit Restaurant and Zazen both on the island. Koh Phangan has a small Indian cluster in Sri Thanu (thalis from ₹718 (~250 THB or ~$7.45)). Koh Tao has one or two Indian spots, plus mushroom burgers and falafel as the default veg backup.
Subodh’s Pro Tip: Strict veg travellers who want Indian food every meal should base on Koh Samui and day-trip to the others. Divers on Koh Tao will eat local Thai and the same Italian cafe three times in a row. That’s the deal.
Getting Connected
All three islands have AIS, dtac, and TrueMove tourist SIMs at the piers and airports, ₹859 (~299 THB or ~$8.91) for 7 days with 15 GB data. Coverage is solid in Chaweng, Sairee, and Sri Thanu, patchier on the mountain roads.
For eSIM, Get Nomad eSIM gets you connected before you fly, 5 GB / 30 days from around ₹964 (~10 USD), no physical card to swap at the airport. Useful if you’re landing at Koh Samui at 11 PM with no SIM kiosk open.
The Bananarchy Take
Here’s the rule I’ve landed on after running this loop for years: chain them in the order Phangan → Samui → Tao, not the other way around. Start with the Full Moon if that’s on your list, drop into Koh Samui for 2-3 nights to catch up on laundry, Indian food, and a proper mall (Central Festival Chaweng has the cheapest pharmacy runs and a Decathlon for any gear you forgot), then finish on Koh Tao for the dive cert. The dive cert is a natural bookend because you’re not rushing to a flight afterwards; the Bangkok sleeper train at the end is a 12-hour ride you’ll be too tired to regret.
If you only have 7 nights total: skip Koh Samui and do Phangan + Tao. If you have 10-14 nights: do all three. If you only have 4-5 nights and can’t decide: Koh Tao if diving, Koh Samui if veg / first-time Thailand, Koh Phangan if the Full Moon is non-negotiable.
Can You Do All Three?
Yes, and it’s the right move if you have 10-14 nights. The ferries between them are 30 minutes to 1 hour 30 minutes, and the cheapest combined route is sleeper train to Surat Thani + ferry to Phangan + ferry to Samui + ferry to Tao + ferry to Chumphon + sleeper train back to Bangkok.
Suggested 12-night itinerary:
- Koh Phangan 5 nights (Full Moon + yoga + beach)
- Koh Samui 3 nights (Indian food, Ang Thong day trip, laundry)
- Koh Tao 4 nights (Open Water course + snorkel)
Cost estimate in THB (12 nights, budget):
| Item | Cost |
|---|---|
| Accommodation (12 nights across dorms) | ₹15,506 (~5,400 THB or ~$160.85) |
| Food | ₹13,783 (~4,800 THB or ~$142.97) |
| Local transport (scooter rentals) | ₹6,892 (~2,400 THB or ~$71.49) |
| Ferries (3 legs) | ₹2,441 (~850 THB or ~$25.32) |
| Sleeper train (Bangkok-Surat Thani + Chumphon-Bangkok) | ₹4,307 (~1,500 THB or ~$44.68) |
| Activities (Full Moon entry, Ang Thong trip, snorkel) | ₹8,040 (~2,800 THB or ~$83.40) |
| Total | ₹50,969 (~17,750 THB or ~$528.71) |
Book on 12go for the Bangkok-Surat Thani sleeper + ferry combo, and Book on 12go for the inter-island ferries.
FAQ
Which island has the best Full Moon Party, Koh Phangan or Koh Samui? Koh Phangan. Samui doesn’t have a regular full moon event. Tickets on Phangan are ₹1,723 (~600 THB or ~$17.87) at the gate, scheduled dates posted on the official Full Moon Party site. Arrive on Haad Rin by 9 PM to avoid the songthaew crush.
Is Koh Tao worth it if I’m not diving? Yes, but only for 3-4 nights. The snorkelling at Mango Bay, Shark Bay, and Aow Leuk is genuinely good, and the island is small enough to feel like a village. For 5+ nights without diving, you’ll get bored. Koh Phangan is the better non-diving choice.
Which island is safest for solo female Indian travellers? All three are reasonably safe, but Koh Samui scores highest because of the airport, hospital, and English-speaking tourist police. Avoid Haad Rin on Koh Phangan during Full Moon if you’re not into crowds. Koh Tao is small enough that everyone knows everyone after 2 days.
Can I get Indian food on all three islands? Yes, but quality varies. Koh Samui has 6+ proper Indian restaurants. Koh Phangan has a small cluster in Sri Thanu. Koh Tao has one or two Indian spots and limited veg backup beyond local Thai.
How do I get from Bangkok to all three cheaply? Sleeper train from Bangkok to Surat Thani (12 hours, ₹2,010 (~700 THB or ~$20.85) second class), then ferry to the island (₹861-₹1,436 (~300-500 THB or ~$8.94-$14.89) depending on which one). Total: ₹2,872-₹3,446 (~1,000-1,200 THB or ~$29.79-$35.74). Koh Samui also has direct flights from ₹10,050 (~3,500 THB or ~$104.25).
When is the worst time to visit the Gulf islands? October and November, when monsoon swells cancel ferries and the Full Moon Party gets rained out. February to June is the safest bet for clear water.
Subodh’s Line
I keep ending trips on Koh Tao. The Open Water cert, the Sairee sunsets, and the fact that the island forces you to slow down because there’s nothing else to do: that’s the move. Start with the chaos of Koh Phangan, rinse off in Koh Samui, then close out in Koh Tao.
