Where is Koh Samui Located?
Koh Samui is Thailand’s second-largest island, covering approximately 228 square kilometers, and sits strategically in the Gulf of Thailand, about 35 kilometers off the east coast near the mainland city of Surat Thani. This tropical gem is part of the Chumphon Archipelago, which includes over 80 islands, with famous neighbors like Koh Phangan (known for its Full Moon Parties) and Koh Tao (a world-renowned diving destination).
The island’s unique location in the Gulf of Thailand gives it distinct weather patterns compared to Thailand’s west coast, making it an excellent year-round destination when other parts of the country experience heavy monsoons. Koh Samui’s strategic position has made it a natural stopping point for centuries of maritime trade, contributing to its rich cultural heritage that visitors can still experience today through local temples, traditional fishing villages, and authentic Thai cuisine.
Although it’s a relatively small island that you can drive around in about 2-3 hours, Koh Samui packs an incredible punch in terms of natural beauty, cultural attractions, and adventure opportunities. The island’s compact size makes it perfect for exploring different areas during your stay, from the bustling beach towns to serene jungle retreats and traditional fishing communities.
How to Get to Koh Samui: Your Complete Transportation Guide
Traveling to Koh Samui is easier than you might think, with multiple transportation options to suit different budgets, time constraints, and travel preferences. The island’s excellent connectivity makes it accessible from major Thai cities and international destinations.
By Plane: Fast and Convenient
Koh Samui Airport (USM) is one of Thailand’s most beautiful airports, featuring an open-air design that immediately gives you that tropical feel upon arrival. Bangkok Airways operates the majority of flights to the island, with daily connections from Bangkok (1 hour 20 minutes), Chiang Mai, Phuket, and Krabi. International flights arrive from Singapore, Hong Kong, Kuala Lumpur, and other regional hubs.
The airport is conveniently located just 2 kilometers from Chaweng Beach, making it incredibly easy to reach your accommodation. While flights can be more expensive than other transportation methods, they save significant time and offer stunning aerial views of the islands during approach and departure.
By Ferry: Budget-Friendly Ocean Adventure
Taking the ferry to Koh Samui is not only more budget-friendly but also adds an element of adventure to your journey. The main ferry routes operate from Surat Thani’s Donsak Pier and the town pier, with several companies offering services throughout the day. The journey takes 1.5-2.5 hours depending on the type of ferry and weather conditions.
High-speed catamarans offer the quickest ferry option, while traditional car ferries are slower but can accommodate vehicles if you’re planning to bring a car. The ferry ride provides beautiful views of the Gulf of Thailand and surrounding islands, making the journey part of your vacation experience.
By Train or Bus + Ferry: The Scenic Route
From Bangkok, you can take an overnight train to Surat Thani (approximately 12 hours) and then transfer to a ferry. This option is perfect for budget travelers and those who want to experience Thailand’s countryside. The train journey offers comfortable sleeper compartments and gives you a chance to see rural Thailand’s beautiful landscapes.
Alternatively, air-conditioned buses run regularly from Bangkok to Surat Thani (8-10 hours), with some companies offering direct bus+ferry combination tickets for seamless travel. This overland route is significantly cheaper than flying and allows you to experience more of Thailand’s diverse scenery along the way.
When Is the Best Time to Visit Koh Samui?
Understanding Koh Samui’s unique weather patterns is crucial for planning the perfect trip. The island’s location in the Gulf of Thailand creates distinct seasonal variations that differ from Thailand’s west coast and northern regions.
Peak Season: December to April
The dry season from December to April represents the absolute best time to visit Koh Samui, with consistently sunny skies, minimal rainfall, and comfortable temperatures ranging from 24-32°C (75-90°F). During these months, you can expect only 2-5 rainy days per month, making it ideal for beach activities, island hopping, and outdoor adventures.
December and January are particularly popular with international visitors escaping winter weather, so expect higher accommodation prices and more crowded beaches. February to April offers the perfect balance of excellent weather and slightly fewer crowds, making it an ideal time for couples and families.
Shoulder Seasons: May to September
May through September sees occasional afternoon showers and higher humidity, but these months offer excellent value for money with lower accommodation rates and fewer tourists. The rain is typically short-lived and predictable, often occurring in late afternoon or evening, leaving mornings and early afternoons perfect for beach activities.
June to August can be particularly appealing for travelers seeking a more authentic local experience, as you’ll encounter more Thai families and domestic tourists rather than international crowds. The lush landscape during these months is incredibly beautiful, with waterfalls at their most impressive.
Rainy Season: October to November
October and November experience the heaviest rainfall, with October being the wettest month averaging 15-20 rainy days. However, even during the rainy season, storms typically come in short, intense bursts followed by clear skies. Many local businesses use this time for renovations and maintenance, so some restaurants and tour operators may have limited schedules.
Insider Tip: Koh Samui’s rainy season is opposite to Thailand’s west coast (Phuket, Krabi), making it an excellent alternative destination when those areas are experiencing monsoons from May to October.

Local Customs: Learn basic Thai greetings (“Sawasdee ka/krap”), show respect for the Thai Royal Family, and avoid pointing feet toward Buddha images or people.
