Local Tips & Practical Know‑How
Best Time to Visit
December through March offers the driest skies and calmer seas. April and May bring heat; September to October are wetter. Still, off-peak travel can yield meaningful savings.
Island Money & Tipping Culture
Thai baht (THB) is standard. For resorts of this caliber, tipping 100–300 THB for good service is common. Spa therapists often welcome a gesture.
Getting Around
Local taxis (songthaews), private transfers, or resort shuttles connect you from Samui Airport. Renting a car or van is helpful if you want to explore beyond the resort.
Eco‑Awareness
Many resorts here engage in turtle nesting protection (e.g., Banyan Tree), locally sourced produce, and limiting single-use plastics. Ask your resort about sustainability programs — your choice matters.
Regional Differences
- Northeast (Bophut / Choeng Mon): better connectivity, mix of local life and luxury
- South / East coast: more secluded, rugged access, fewer services off-hours
- Lamai & hillside zones: more peaceful, greener — but steeper roads
