Samui Airport or a ferry arrival?

Samui Airport, USM, serves stays around Chaweng, Bophut, Lamai and other parts of the island. Save the meeting instructions from your driver or accommodation before flying, with the actual reception entrance beside your reservation. Arriving by ferry instead? Send your driver the island arrival pier printed on the ticket. Keep any mainland connection separate so a Donsak departure pin does not become your Samui pickup location.

Island rides and four Samui places

Booked transfers, taxis and songthaews can help with journeys between coastal areas. Agree on your destination and pickup arrangements before setting off, and download the route before crossing the island’s hills, where terrain can interrupt reception. Save your host’s contact and vehicle-access instructions before approaching a hillside villa. At busy beaches or markets, keep the return meeting point available offline rather than searching for it after dinner.

  • Chaweng: pin the resort’s road entrance and lobby, not just its beach frontage, before arranging a pickup.
  • Lamai: save the restaurant doorway and the beach access nearest your accommodation before an evening walk.
  • Bophut Fisherman’s Village: agree on a specific meeting point and check your driver’s pickup instructions around the walking streets.
  • Wat Plai Laem: download the entrance and onward route before visiting, and keep photography and dress guidance in mind.

Samui-specific tip: Nathon, Lipa Noi, Maenam and Bangrak are different pier areas. Match the operator, pier and check-in point on your booking before leaving your hotel for a departure.

For a boat excursion, download the operator’s meeting instructions, booking and return arrangements while ashore. Check current weather and provider guidance before travelling, and keep essential details available offline during the crossing.
