Koh Larn vs Phuket
They get lumped together as ‘Thai islands’, but Koh Larn and Phuket are opposite coasts and opposite scales. Here’s the honest difference — and how to choose, or fit both into one trip.
Updated 16 June 2026 · We visit. We don't sell placement.
Phuket and Koh Larn are different-scale, opposite-coast trips. Phuket is Thailand’s largest island — a full Andaman resort destination with its own international airport and days’ worth of beaches — while Koh Larn is a tiny Gulf island you visit for a single beach day from Pattaya. They’re around 970 km apart by road, so most people choose one per trip or fly between them. Pick Phuket for a beach holiday; Koh Larn for a beach day.

Phuket in brief
Phuket is Thailand’s largest island, 543 km² on the Andaman (west) coast, joined to the mainland by a bridge and served by its own international airport. It’s a complete holiday destination — dozens of beaches, big resorts, Old Town, world-famous nightlife at Patong and a fleet of boat day-trips to Phi Phi and Phang Nga Bay.

From Phuket to Koh Larn
Phuket and Koh Larn sit on opposite seaboards — Andaman versus Gulf — around 970 km apart by road. There’s no sensible direct hop; if you want both, you fly between the regions.
- Getting to Phuket
- Fly into Phuket International (HKT), about 1¼–1½ hours from Bangkok and well connected internationally. The airport sits on the north of the island; Patong and the main west-coast beaches are roughly 40 minutes south by taxi or bus.
- Phuket → Koh Larn
- Realistically a full travel day: fly Phuket back to Bangkok (or, where it runs, to U-Tapao near Pattaya), then road to Pattaya, then the 40฿ ferry from Bali Hai. Most travellers don’t commute between the two — they pick one region per trip.
- The easy call
- If your trip is built around Pattaya or Bangkok, Koh Larn is the beach day that’s already on your doorstep. Save Phuket for a trip where the Andaman coast is the main event.
Phuket vs Koh Larn
Same word — ‘island’ — completely different trips. Side by side:
| Compare | Phuket | Koh Larn |
|---|---|---|
| What it is | Thailand’s largest island; a full resort destination | A small day-trip island off Pattaya |
| Sea & region | Andaman Sea, southern west coast | Gulf of Thailand, eastern seaboard |
| Size | 543 km² | ≈4.6 km long — walkable in spots |
| Getting there | Fly to Phuket (HKT), ~1¼–1½ hr from Bangkok | 40฿ ferry from Pattaya, 30–45 min |
| Time you need | 3–7 days | Half a day to a full day |
| Beaches | Many — Patong, Karon, Kata, Kamala, Surin… | Eight small ones, Tawaen the main |
| Vibe | Big resorts, malls, famous Patong nightlife | Low-key beach day, hilly, a few restaurants |
| Day trips | Phi Phi, James Bond Island, the Similans | The island itself is the day trip |
| Cost | Higher — flights plus multi-night hotels | Cheap — ferry and lunch, no hotel needed |
| Best for | A full beach holiday | A beach escape from Pattaya or Bangkok |
Distances, fares and times are approximate and verified mid-2026 — they change, so confirm on the day. The Koh Larn ferry figure is the public boat from Bali Hai Pier; see Getting There for the detail.
A few landmarks in Phuket
Which one, and when
A multi-day Andaman beach holiday with nightlife and boat trips
A quick, cheap beach day while you’re on the Pattaya side
Doing both is possible but it’s a flight, not a transfer — fly Phuket–Bangkok and continue to Pattaya for Koh Larn, or vice versa. For most one- or two-week trips it’s cleaner to make Phuket the beach focus on its own, or stick to the Pattaya side and let Koh Larn be your beach day. Don’t plan on casually visiting both in a long weekend.
The verdict: Phuket is a destination; Koh Larn is a day out. If the Andaman coast is your trip, go to Phuket and give it several days. If you’re based around Pattaya or Bangkok, don’t fly across the country for a beach — Koh Larn is the easy, 40฿-ferry version that’s already next door.
Phuket & Koh Larn — common questions
Is Koh Larn better than Phuket?
Neither is ‘better’ — they do different jobs. Phuket is a full resort island with an airport, dozens of beaches and days of boat trips; it suits a whole beach holiday. Koh Larn is a small island you reach by a 40฿ ferry from Pattaya for a single beach day. If you want a holiday destination, Phuket; if you want an easy beach day near Pattaya or Bangkok, Koh Larn.
Can you visit both Phuket and Koh Larn in one trip?
Yes, but they’re on opposite coasts around 970 km apart, so you fly between them — typically via Bangkok. It only makes sense on a longer trip; for a short one, pick the region you’d rather spend your beach time in.
How far is Phuket from Pattaya and Koh Larn?
Around 970 km by road — Phuket is on the Andaman (west) coast and Pattaya is on the Gulf (east). There’s no quick crossing; people fly. That distance is exactly why Koh Larn, 7 km off Pattaya, is the practical beach day if you’re already on the eastern side.
Which is cheaper, Phuket or Koh Larn?
A Koh Larn day is far cheaper — a 40฿ ferry, lunch and maybe a sunbed, with no hotel needed if you’re staying in Pattaya. Phuket is a multi-night holiday: flights, a hotel and paid boat day-trips add up. They’re really different budgets for different trips.
