Question

Accepted Answer

Direct answer

Koh Samui is a popular Thai island offering beaches, temples, nightlife, and outdoor activities. Plan for weather variability, boat/flight connections, and local customs to make the most of your trip.

Visa / Entry Requirements

- Many nationalities receive a 30-day visa exemption on arrival (Thailand); some get 15/90 days—check with your embassy before travel.
- Passport must be valid for at least 6 months on arrival; carry return/onward ticket proof and sufficient funds if asked.
- For stays longer than the visa-free period, apply for a visa in advance or extend at the local immigration office in Thailand.

Best Time to Visit

- Ideal: December to April — dry season, warm seas, calm weather.
- Shoulder months: November and May — possible rain but fewer crowds and lower prices.
- Wet season: September–October (and occasional storms in October) — expect heavier rains and rough seas; some tours may be canceled.

Safety Tips

- Swim only at lifeguarded/marked beaches; currents can be strong, especially during monsoon.
- Watch out for scooter accidents — helmets are mandatory and roads can be narrow/steep. Rent from reputable vendors; inspect brakes/lights.
- Beware of petty theft; use hotel safes for valuables and avoid leaving things unattended on beaches.
- Tap water isn’t safe to drink; use bottled or filtered water.

Local Customs & Etiquette

- Respect the Thai Royal Family; criticism is illegal and culturally offensive.
- Dress modestly when visiting temples: shoulders and knees covered; remove shoes before entering buildings.
- Use polite greetings (wai) and a soft tone; point with the whole hand rather than a single finger.
- Negotiation: haggling is common in markets but do so politely.

Currency & Money

- Currency: Thai Baht (THB). Cash is king for markets, small vendors, and taxis; ATMs are widely available in Chaweng and Lamai.
- Credit cards accepted at hotels, many restaurants, and larger shops; expect small-card-surcharge s
