The short version

Koh Samui is Thailand's second-largest island, situated in the Gulf of Thailand and defined by palm-fringed coastlines, coconut groves, and mountainous rainforest. Evolving from a backpacker enclave and coconut farming hub into an established resort destination, it balances developed tourism infrastructure with accessible tropical landscapes. Koh Samui primarily functions as a beach, wellness, and nightlife destination, catering to independent travelers, luxury holidaymakers, and families. It suits visitors seeking upscale beachfront lodging, active dining and beach club scenes, wellness retreats, and aquatic day trips to Mu Ko Ang Thong National Marine Park, while retaining quieter pockets of relaxed coastal village life along its northern shores.

Best time: Late December to April for dry, sunny weather; avoids the heavy October–November Gulf monsoon.

Local know-how

Good to know

Island taxis rarely turn on meters; negotiate and fix the exact fare before stepping into a cab, or book via Grab or Bolt to ensure standard rates.
Red songthaews operate as shared public transport along the coastal ring road during daylight hours; flag one down, confirm your destination, and pay 50–100 THB per passenger upon exit.
Koh Samui operates on a distinct Gulf weather system; avoid planning trips in October and November when heavy monsoon downpours and rough seas routinely disrupt ferries and boat tours.
Always carry Thai Baht cash for night markets, family-run roadside eateries, and songthaews, as small merchants do not accept cards and card payments elsewhere often incur a 3% surcharge.
When renting scooters, check brakes and tire tread carefully, ensure your International Driving Permit includes motorcycle certification, and wear helmets to avoid strict police checkpoints.
