Whether you’re plotting your route or dreaming of what awaits, this guide has you covered with everything you need to know about getting there and soaking up all that Koh Samui has to offer.

How to Travel from Koh Lanta to Koh Samui

Travelling from Koh Lanta to Koh Samui is an exciting jaunt across the Andaman Sea and Gulf of Thailand, with a few transport options to suit your style and budget. The journey typically involves a mix of ferry, bus, and sometimes speedboat, taking you from Koh Lanta’s Saladan Pier to Koh Samui’s Nathon Pier.

Ferry and Bus: The most popular and affordable option, this combo starts with a ferry from Saladan Pier to Krabi (about 1-1.5 hours, 350-450 THB). From Krabi, hop on a bus to Surat Thani (around 4-5 hours, 250-350 THB), then catch another ferry to Koh Samui (1.5 hours, 300-400 THB). Total cost: roughly 900-1,200 THB, with a journey time of 8-10 hours. It’s a scenic ride, perfect for soaking in Thailand’s coastal charm.

Speedboat and Bus: For a quicker trip, take a speedboat from Koh Lanta to Krabi (30-45 minutes, 700-800 THB), then a bus to Surat Thani, followed by the ferry to Koh Samui. This shaves off a couple of hours, costing around 1,300-1,600 THB total. Speedboats are weather-dependent, so check conditions in advance.

Flight Option: If time’s tight, consider a ferry to Krabi, then a short flight from Krabi Airport to Koh Samui (under 1 hour, 2,500-4,000 THB). Add the ferry and transfers (around 600-800 THB), and you’re looking at 3,100-4,800 THB for a 5-6 hour trip. It’s pricier but ideal for a swift escape.

Booking ahead is a must during peak season (December to April) to snag the best rates and seats. Whichever route you choose, the journey sets the stage for Koh Samui’s tropical allure.

Weather and Seasons of Koh Samui All Year Round

Koh Samui’s tropical climate makes it a year-round destination, but the seasons shape your experience. Here’s what to expect:

Dry Season (December to April): The prime time to visit, with temperatures between 25°C and 32°C, sunny skies, and calm seas. It’s perfect for beach days and outdoor fun, though it’s also the busiest and priciest period.

Hot Season (March to August): Things heat up to 35°C, staying mostly dry until late summer. Humidity climbs, but fewer crowds mean a more relaxed vibe - ideal if you can handle the warmth.

Rainy Season (September to November): Monsoon season brings heavy rain and rough seas, with temperatures around 27°C-30°C. October and November are the wettest, often disrupting ferry schedules. Prices drop, making it a budget-friendly gamble if you’re flexible.

For the ultimate Koh Samui experience, aim for January to March - gorgeous weather without the peak-season crush.
