A good Koh Samui map is the single most useful planning tool you can have before arriving on the island. Koh Samui is larger than most visitors expect — 228 km² of coastline, jungle interior and mountain ridge — and the distances between the main beach areas are significant enough that choosing the wrong base can cost you two hours a day in taxi rides. This complete Koh Samui map guide covers every area of the island in 2026: where the beaches are, where the piers sit, where the best hotels and restaurants are located, and exactly how to navigate the 51 km ring road that circles the entire island.
According to the Tourism Authority of Thailand, Koh Samui covers 228.7 km² — making it Thailand's third largest island after Phuket and Koh Chang, and significantly larger than it appears on standard tourist maps.

Koh Samui Map — Island Overview
Island size: 228.7 km² · Coastline: 51 km (ring road) · Highest point: Khao Pom 635m · Main beach areas: 8 · Airport: Northeast coast (USM) · Main pier: Nathon (west coast) · Shape: Roughly oval, mountains in centre
The Koh Samui map is best understood as a series of distinct coastal zones surrounding a mountainous jungle interior. The ring road (Route 4169) circles the entire island at low elevation, connecting all the main beach areas. The interior is largely undeveloped jungle — the Na Muang waterfalls are the main reason visitors venture inland. Understanding the Koh Samui map orientation is essential: the airport is on the northeast coast, the main ferry pier is on the west coast, and the most popular beaches are on the east and north coasts.
Koh Samui Map — The Ring Road Explained
The 51 km ring road is the backbone of the Koh Samui map — the single road that connects every beach, every town and every attraction on the island. Driving it by scooter is one of the best ways to understand the island's geography. Here is the complete ring road circuit clockwise from Nathon Pier:
| Section | Distance | Drive Time | Key Stops on Koh Samui Map |
|---|---|---|---|
| Nathon → Maenam | 8 km | 15 min | Nathon town · Lipa Noi beach · Maenam village |
| Maenam → Bophut | 5 km | 10 min | Maenam beach · Bang Rak pier · Big Buddha |
| Bophut → Chaweng | 7 km | 12 min | Fisherman's Village · Chaweng Lake · Chaweng beach |
| Chaweng → Lamai | 8 km | 12 min | Chaweng Noi · Silver Beach · Coral Cove |
| Lamai → Thong Krut | 10 km | 20 min | Hin Ta Hin Yai · Na Muang waterfalls turnoff · South coast |
| Thong Krut → Nathon | 13 km | 25 min | Taling Ngam · Lipa Noi · West coast viewpoints |
Drive the ring road clockwise — you keep the sea on your left for most of the circuit, which gives you better views and easier beach access. Start at 7am from Nathon to catch the west coast in the morning calm, reach Chaweng by 9am and Lamai by 10am. The south coast section (Lamai to Thong Krut) has the most dramatic scenery and fewest tourists.
Koh Samui Map — North Coast
The north coast runs from the airport area west through Bophut and Maenam to the top of the island. It is the most civilised and characterful stretch of coastline — the expat community's favourite, the location of the island's best weekly market (Bophut Friday Night Walking Street), and home to the Four Seasons Resort, the finest hotel on the island.
Key locations on the north coast:
- Maenam Beach — 4 km of flat, calm beach. Best for families. Monday Night Market in the village.
- Bophut / Fisherman's Village — original Sino-Portuguese shophouses. Friday Night Market. Best restaurants on the north coast.
- Bangrak Pier (Big Buddha Pier) — ferries to Koh Phangan and Koh Tao. Walking distance from the Big Buddha temple.
- Big Buddha Temple (Wat Phra Yai) — 12-metre golden Buddha on a small island causeway. Most visited temple on the Koh Samui map.
- Wat Plai Laem — 18-armed Guanyin statue on a lake. Less visited than Big Buddha but equally impressive.
Koh Samui Map — East Coast
The east coast is the most developed and most visited section of the island — dominated by the 7 km arc of Chaweng Beach and the 4 km strip of Lamai Beach. This is where the island's main tourism infrastructure is concentrated: the most hotels, the most restaurants, the most water sports and the main nightlife strip. The airport (USM) sits at the northern end of the east coast.
Key locations on the east coast:
- Koh Samui Airport (USM) — northeast corner of the island. Taxis to Chaweng: 15 min. To Bophut: 15 min. To Lamai: 35 min. To Nathon Pier: 40 min.
- Chaweng Beach — the longest and most complete beach on the island. Main tourist strip. Airport 15 min north.
- Chaweng Lake — freshwater lake behind the north end of Chaweng Beach. Marks the quiet northern end of the strip.
- Silver Beach (Ao Thong Takian) — secluded cove between Chaweng and Lamai. Accessible via steep track off the main road.
- Coral Cove — small rocky cove with the clearest water on the east coast. Best snorkeling directly from shore.
- Lamai Beach — second major beach on the east coast. More local, less commercial than Chaweng.
- Hin Ta Hin Yai — Grandmother and Grandfather Rocks at the southern end of Lamai. Famous geological formation.
Koh Samui Map — South Coast
The south coast is the least developed and most authentic stretch of coastline — a largely undiscovered stretch of coastline that most tourists never reach. The road here climbs through jungle, drops past local fishing villages and delivers some of the most spectacular scenery on the island. The Na Muang Waterfalls are accessed via a road cutting north from the south coast into the island interior.
Key locations on the south coast:
- Na Muang Waterfall 1 & 2 — access road off the south coast ring road. Na Muang 1: 5-min walk. Na Muang 2: 20-min jungle hike. Both free.
- Wat Khunaram — temple with the preserved body of a mummified monk. South coast road, between Lamai and Thong Krut.
- Hua Thanon village — Muslim fishing village with the best southern Thai halal food on the island. Excellent morning market.
- Thong Krut Beach & Pier — authentic fishing village. Departure point for Five Islands longtail boat trips.
- Bang Kao Beach — completely undeveloped beach. No facilities. One of the wildest spots on the Koh Samui map.
The south coast section of the Koh Samui map is best experienced on a ring road scooter day — the road climbs and drops dramatically through jungle with occasional sea views that are genuinely spectacular. Stop at Wat Khunaram (free), the Hua Thanon Muslim market (morning only), and Thong Krut for a fresh seafood lunch before continuing west.
Koh Samui Map — West Coast
The west coast is the sunset coast — facing directly west over the Gulf of Thailand toward the limestone islands of Ang Thong Marine Park. It is the quietest and least touristy section of the coastline, home to the main ferry pier at Nathon and some of the island's most dramatic sunset views. The InterContinental Koh Samui and Nikki Beach Resort are both on the west coast.
Key locations on the west coast:
- Nathon Pier — the main ferry terminal on the Koh Samui map. All mainland ferries (Raja, Seatran, Lomprayah) depart from here. Ferry to Surat Thani/Donsak: 1h–1h30.
- Nathon Town — the island's administrative capital. Best local food market. Least touristy town on the island.
- Taling Ngam Beach — best sunset beach on the Koh Samui map. West-facing. InterContinental hotel here.
- Lipa Noi Beach — quiet, golden sand beach. Local fishing village. No tourist facilities — bring everything.
- Ang Thong Marine Park — visible on the horizon from the west coast. 45 min by speedboat. Day trips depart from various piers.

How to Navigate the Koh Samui Map
The island is straightforward to navigate once you understand the basic geography. Here are the tools and tips that make getting around easy:
Google Maps on Koh Samui: Works excellently across the entire island. Download the offline map of Koh Samui before arriving — this is the most important navigation step on the Koh Samui map. An offline map means you navigate without using mobile data and without needing a signal in the occasional dead spots on the south coast road.
The ring road logic: Almost everything on the Koh Samui map is on or near the ring road (Route 4169). If you know which direction your destination is from your current position, you can find anything. Clockwise from Nathon: north coast → east coast → south coast → west coast.
Grab app: Works across the island and shows real-time driver locations on the map. Consistently 15–20% cheaper than negotiated taxis. Download and set up before arriving using your Thailand eSIM which activates the moment you land.
Scooter rental: The best way to use the Koh Samui map independently. A scooter from Tonton Samui Rental gives you complete freedom to stop wherever something looks interesting — a viewpoint, a hidden beach, a local market. The full circuit takes 2.5–3 hours without stops.
The island is bigger than it looks on a standard tourist map. The drive from Nathon Pier (west) to Chaweng Beach (east) takes 30–35 minutes on the ring road — not the 15 minutes that many visitors assume. Always factor travel time into your planning, particularly if connecting a mainland ferry arrival at Nathon Pier with accommodation at Lamai or further south.
Koh Samui Map — Interactive Navigation Tips
- Save key locations before arriving: In Google Maps, save Nathon Pier, your hotel, the Big Buddha, Na Muang Waterfall, and Bophut Fisherman's Village before you fly. These five points cover essential navigation and let you orient yourself immediately on arrival.
- GPS coordinates for Nathon Pier: 9.5349°N, 100.0588°E — the starting point for all mainland ferry journeys.
- Airport GPS coordinates: 9.5478°N, 100.0616°E — northeast corner of the island.
- Big Buddha GPS: 9.5644°N, 100.0655°E — north coast, near Bangrak Pier.
- The interior mountain road: There is a road across the mountain interior connecting the north coast to the south coast directly — approximately 12 km but significantly slower than the ring road. Scenic but requires a confident scooter rider on the steep sections.
FAQ — Koh Samui Map
How big is Koh Samui?

The island is roughly oval in shape with a mountainous jungle interior and a coastal ring road connecting all the main beach areas.
Where is the airport on the Koh Samui map?

How do I get around Koh Samui without a map?
The ring road logic makes it easy — if you know you are going clockwise or anti-clockwise from your current position, you can navigate the entire island without a detailed map.
