If you are planning a Thailand island hopping route, the first decision is coast. Thailand island hopping is not one route. It is two completely separate worlds, divided by the peninsula, served by different ferry companies, and ruled by opposite monsoon calendars. Pick the wrong side for your travel month and you will spend a week looking at brown surf and closed dive shops. Pick the right corridor, in the right order, with the right connections booked in advance, and the same week becomes the trip you tell people about for years. You may also find [Koh Samui Crowded Backpacking Guide](/route/koh-samui-crowded-backpacking-guide/) useful for this trip.

> **Subodh's Pro Tip**: Don't try to do both coasts in one trip unless you have at least 18 days. The internal transit (Phuket to Koh Samui by bus + ferry) eats a full day and costs more than flying from Bangkok. Pick one side and go deep. For related planning, see our guide on [Koh Samui Crowded Backpacking Guide](/route/koh-samui-crowded-backpacking-guide/).
## Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Best months for the Andaman coast (Phuket, Krabi, Phi Phi, Koh Lipe) | November to April (dry season, calm Andaman Sea) |, |
| Best months for the Gulf coast (Koh Samui, Koh Phangan, Koh Tao) | May to September (dry season, calm Gulf of Thailand) |, |
| Cheapest inter-island ferry (e.g. Koh Samui to Koh Phangan) | Seat on the public car ferry, 30 minutes | ₹574 (\~200 THB or \~$5.94) |
| Longest ferry leg on the Andaman route (Krabi to Koh Lipe) | Speedboat via Pak Bara pier | ₹3,873 (\~1,350 THB or \~$40.12) |
| Cheapest dorm on a popular island (Koh Phangan, off-party week) | Fan dorm in a shared room | ₹746 (\~260 THB or \~$7.73) |

> **Safety Alert**: The TDAC (Thailand Digital Arrival Card) is mandatory for every entry, even visa-free stays. Fill it at the official portal before you board, not after landing: https://tdac.immigration.go.th. Airline check-in agents have started denying boarding to passengers without a QR code.
## The Two Corridors
Thailand's islands fall into two distinct clusters. The strait between them is 600 km of land and sea, so most travellers do one side per trip.
**Andaman Coast (west, Indian Ocean side):** Phuket, Koh Phi Phi, Krabi (Railay, Ao Nang), Koh Lanta, Koh Mook, Koh Lipe. Limestone karsts rising out of turquoise water, dense jungle, better snorkelling, bigger day-trip scene. Reached from Phuket or Krabi airports.
**Gulf Coast (east, South China Sea side):** Koh Samui, Koh Phangan, Koh Tao, Koh Chang (further north near Cambodia), Koh Kood. Coconut palms, white sand, calmer shallows, the Full Moon Party on Koh Phangan, the dive cert capital of the world on Koh Tao. Reached from Surat Thani, Koh Samui, or Chumphon.
## Why Season Matters More Than Route
This is the part most guides get wrong. The Andaman and Gulf coasts have opposite monsoon seasons. They are not both "dry in December" as the Instagram captions suggest.
- Andaman dry season: **November to April**. The Sea is flat, ferries run on time, Maya Bay is open, Koh Lipe is reachable.
- Andaman wet season: **May to October**. Big swells cancel ferries to Koh Lipe and the Trang islands routinely. Maya Bay closes for reef regeneration most years.
- Gulf dry season: **May to September**. Koh Tao dive visibility is at its best, Koh Phangan Full Moon parties are rain-free.
- Gulf wet season: **October to December**. Koh Samui regularly floods in November, with periodic ferry cancellations reported across the Gulf corridor.
The two best windows overlap only briefly in late December and early January, and that overlap is when prices double and ferries sell out. If you can travel flexibly, the sweet spot for the Andaman is **mid-November through mid-March**, and for the Gulf **mid-March through August**.
## The Andaman Corridor: Phuket → Phi Phi → Krabi → Koh Lanta → Koh Lipe
This is the route most first-timers take, and the one that fits a 7 to 14 day window.
**Day 1 to 2: Phuket.** Patong is a nightlife hub; if that is what you want, base yourself there, otherwise stay in Old Phuket Town or near Kata/Karon for a quieter base. From Phuket, ferries leave Rassada Pier for Koh Phi Phi (2 hours) and Krabi's Klong Jilad Pier.
**Day 3 to 4: Koh Phi Phi.** Walkable, no cars, the view from the viewpoint is worth the 30-minute climb, and the day-trip boats to Maya Bay and Bamboo Island are the main reason most people come. Two nights is enough. Ferries continue from Phi Phi to Krabi (1.5 hours) and Koh Lanta (1 hour 30 minutes).
**Day 5 to 6: Krabi (Ao Nang / Railay).** Base yourself in Ao Nang and day-trip to Railay Beach (longtail boat, ₹574 (\~200 THB or \~$5.94)) and the Four Islands. To reach the ferry to Koh Lanta, head back to Klong Jilad pier in Krabi town (about 20 km from Ao Nang, 30 minutes by songthaew). From Klong Jilad, the ferry to Koh Lanta takes about 2 hours via the slower car ferry, or 1 hour 30 minutes by speedboat.
**Day 7 to 9: Koh Lanta.** Longer, quieter, family-friendly. Good for yoga, scooter loops along the west coast beaches, and diving day trips run by local operators out of Klong Dao. From Koh Lanta, the only onward ferry of consequence is the speedboat to Koh Lipe (3 to 4 hours, Bundhaya or Satun Pakbara), book a day ahead, it does not run every day in shoulder season.
**Day 10 to 12: Koh Lipe.** Tarutao National Marine Park, the closest Thai island to Malaysia (Langkawi is 1.5 hours by speedboat), walkable in 20 minutes, no cars. Snorkelling off Pattaya Beach is fine; Sunrise Beach on the east side is usually the better spot.
**Connection to leave the corridor:** Koh Lipe connects to Langkawi (Malaysia) by speedboat, or back to Pak Bara pier on the mainland (1.5 hours) for buses to Hat Yai and flights out of Hat Yai International.
## The Gulf Corridor: Koh Samui → Koh Phangan → Koh Tao
The classic backpacker triangle. Three islands, three identities, all reachable from Surat Thani or Chumphon on the mainland.
**Day 1 to 2: Koh Samui.** Skip Chaweng unless you want the Patong vibe with a Samui price tag. Stay in Bophut or Maenam. The ferry pier to Koh Phangan is at Bangrak (Lipa Noi for car ferries); the slow car ferry takes 1.5 hours, a high-speed catamaran takes about 30 minutes. A catamaran ticket costs roughly ₹1,004 (\~350 THB or \~$10.40) and is worth it if you are not staying near the west coast ferry pier.
**Day 3 to 5: Koh Phangan.** Two faces. Outside Full Moon Party week (every month around full moon; check the official Koh Phangan tourism calendar for exact dates) it is budget hostels and quiet north-shore beaches. During party week it is the loudest place in Thailand and dorm prices quadruple. Match the dates before you book the ferry, not the other way around.
**Day 6 to 10: Koh Tao.** Long established as a budget place to get PADI Open Water certified, with course-plus-accommodation packages typically quoted in the low four figures (THB). The ferry from Koh Phangan to Koh Tao takes about 1.5 hours on a high-speed catamaran.
**Connection to leave the corridor:** Koh Tao's only ferry pier is Mae Haad. From there, a high-speed catamaran goes direct to Chumphon (1.5 hours) where trains and buses run to Bangkok (8 hours overnight train, sleeper berth around ₹2,295 (\~800 THB or \~$23.78)).
## Where to Stay: Budget Dorms by Island
Dorms on the Thai islands have a wider price range than mainland Thailand because of the supply-and-demand swing with monsoon and party seasons.
| Island | Dorm price (THB) | Dorm price (INR) | Best for |
|---|---|---|---|
| Koh Phi Phi | ₹1,004-₹1,721 (\~350-600 THB or \~$10.40-$17.83) | ₹1,000 (\~$10.36) to ₹1,720 (\~$17.82)| First night out of Phuket, easy walking around the pier |
| Koh Lanta | ₹717-₹1,291 (\~250-450 THB or \~$7.43-$13.37) | ₹720 (\~$7.46) to ₹1,290 (\~$13.36)| Longer stays, quieter base |
| Koh Lipe (Nov to Apr only) | ₹1,434-₹2,582 (\~500-900 THB or \~$14.86-$26.75) | ₹1,430 (\~$14.81) to ₹2,580 (\~$26.73)| Last Andaman stop, walkable island |
| Koh Samui | ₹861-₹1,578 (\~300-550 THB or \~$8.92-$16.35) | ₹860 (\~$8.91) to ₹1,580 (\~$16.37)| Bophut side, skip Chaweng |
| Koh Phangan (non-party) | ₹746-₹1,119 (\~260-390 THB or \~$7.73-$11.59) | ₹750 (\~$7.77) to ₹1,120 (\~$11.60)| Off-peak yoga trip |
| Koh Phangan (Full Moon week) | ₹4,304-₹6,312 (\~1,500-2,200 THB or \~$44.58-$65.39) | ₹4,300 (\~$44.55) to ₹6,310 (\~$65.37)| Only if you are staying for the party |
| Koh Tao | ₹1,004-₹1,721 (\~350-600 THB or \~$10.40-$17.83) | ₹1,000 (\~$10.36) to ₹1,720 (\~$17.82)| Dive course accommodation, often bundled |
Check hostel prices before booking the ferry, especially on Koh Phangan in party weeks, dorms sell out by Wednesday.
For a complete breakdown of ferry routes, timings, and prices across Thailand, see our [Thailand Islands Ferry Guide](/guide/thailand-islands-ferry-guide-routes-timings-prices-map/).
## Option 1: Cheapest (Slow Ferries and Night Buses)
The cheapest end-to-end Andaman crossing is around ₹3,443 (\~1,200 THB or \~$35.67) if you take the slow government car ferries and overnight buses between Koh Lanta and Krabi town. The cheapest Gulf crossing is around ₹2,582 (\~900 THB or \~$26.75) using the Raja Ferry from Samui to Phangan and the overnight train from Chumphon to Bangkok.
Time penalty is real. Slow ferries take 1.5 to 2.5 hours versus 30 to 90 minutes for the speedboats. Overnight buses save a night's accommodation but you will arrive wrecked. Acceptable only if you have unlimited time and a small budget.
## Option 2: Best Experience (Mixed Speedboat + Sleeper Train)
This is the route Subodh would recommend to a close friend: speedboat ferries between islands on each corridor, sleeper train from Chumphon or Hat Yai back to Bangkok. Total transport cost lands around ₹6,886-₹8,607 (\~2,400-3,000 THB or \~$71.33-$89.17) for the full Andaman corridor plus the train out. You spend your day hours on islands instead of in terminals, and the sleeper train is an experience in itself (2nd class air-con berth around ₹2,295 (\~800 THB or \~$23.78)).
Book the sleeper train at least a week ahead on the State Railway of Thailand site or via [12go.asia](https://12go.asia?z=16187692) during peak season.
## Option 3: Fastest (Fly + Speedboat)
Phuket to Koh Samui by direct flight is about 1 hour 15 minutes, typically around ₹6,886 (\~2,400 THB or \~$71.33) one-way on carriers that operate the route. Add a high-speed catamaran from Koh Samui to Koh Phangan and you are on the party beach the same afternoon. Useful if you have under a week and want both coasts, but the flight alone costs more than two full days of inter-island ferries.
## Indian Passport Specifics
Indians get a bilateral **visa-free entry for 60 days**. You must fill the **TDAC** arrival card at https://tdac.immigration.go.th before boarding, free of charge.
For island hopping you do not pass an immigration checkpoint, so your 60-day clock keeps ticking across all islands. The only time you hit immigration is the airport pier on Phuket, Krabi, Samui, or Surat Thani, or at the Pak Bara / Hat Yai mainland exit.
Carrying Indian food products onto the islands is fine, but bringing fresh fruit across marine park boundaries (Koh Lipe's Tarutao, Koh Tao's Marine Park) can get you fined at park checkpoints. Buy fruit on the island you are entering, not before.
Carry photocopies of your passport bio page separately from the original. At smaller Thai immigration posts like Trang or Satun (relevant if exiting via Pak Bara pier), officers may ask to see the original alongside your photocopy, so keep both accessible.
## When NOT to Take This Route
- **Andaman coast, May to October**: ferries to Koh Lipe and the Trang islands are cancelled frequently in peak monsoon (September to October). Maya Bay is closed for most of this window. Take the Gulf corridor instead.
- **Koh Samui, October to mid-December**: heavy rain, flooding, reduced ferry schedules. Avoid for the bucket-list trip.
- **Full Moon Party week on Koh Phangan**: avoid if you want a quiet beach trip. The whole island transforms; expect double prices, triple crowds, and noise across every beach.
- **Songkran (mid-April)**: ferries still run but mainland travel to the piers is disrupted. Book the bus and ferry together.
Check the official Thai Meteorological Department seasonal forecast closer to your dates: https://www.tmd.go.th/en/.
## Getting Connected
Thailand mainland has solid 4G coverage on both coasts. On the islands, signal is good in populated bays (Chaweng, Haad Rin, Patong, Klong Dao on Lanta) and patchy on the smaller beaches. AIS and TrueMove are the two main networks; both sell tourist SIMs at Phuket and Samui airports. For longer plans with more data, head to a 7-Eleven counter and ask for the current tourist data package.
If you want connectivity from the moment you land, or you are switching between islands and want to skip the SIM kiosk, look for eSIM providers that cover Thailand and activate before you fly. Scan the QR on landing, and you are online before the queue at immigration.
## FAQ
**Do I need a visa for Thailand island hopping?**
Indian passport holders get 60 days visa-free. Fill the TDAC arrival card before you fly.
**Which coast is better for first-time visitors?**
The Andaman (Phuket, Phi Phi, Krabi, Koh Lanta) has the more dramatic scenery and is the safer bet for December to March travel. The Gulf (Samui, Phangan, Tao) is better for May to September, and for the Full Moon Party experience specifically.
**Can I island hop during monsoon season?**
On the Andaman coast, expect cancellations to Koh Lipe, the Trang islands, and the Similan islands between May and October. On the Gulf coast, expect slower boats and some rain, but services usually run. Check 12go's live status the day before departure.
**How much cash should I bring?**
Most island ferries, hostels, and restaurants accept card, but smaller longtail boats and fruit stalls are cash-only. Bring ₹8,607-₹14,345 (\~3,000-5,000 THB or \~$89.17-$148.61) in small notes for a week on the islands.
**Is the Full Moon Party worth it?**
If you like 10,000-person beach parties, yes. If not, avoid the dates entirely. The rest of Koh Phangan is unrecognizable during Full Moon week. Check the official Koh Phangan tourism calendar for exact dates.
**What is the cheapest way to get from Bangkok to the islands?**
Night train or VIP bus from Bangkok to Surat Thani (around ₹1,721-₹2,295 (\~600-800 THB or \~$17.83-$23.78)), then ferry to Koh Samui or Koh Phangan (₹574-₹1,004 (\~200-350 THB or \~$5.94-$10.40)). Total around ₹2,869 (\~1,000 THB or \~$29.72) and 12 hours door-to-door.
## Subodh's Take
Pick one coast, pick the season that matches it, and commit. The mistake I see Indian backpackers make most often is trying to cram both coasts into 10 days because some article told them "you can do Thailand in a week." You can, but you will not remember the islands, only the buses. The Andaman in February is the single best combination Thailand offers, and the Gulf in June is the second-best. If you have 14 days, do the Andaman corridor and end with a sleeper train back to Bangkok. If you have 10, do Phuket, Phi Phi, and one of Krabi or Koh Lanta. Anything shorter than a week on the islands is a tease.
**Travel Insurance**: Buy a travel insurance policy that covers medical evacuation and trip interruption across Southeast Asia before you fly. Compare plans from licensed providers in India and pick one that explicitly covers Thailand.
