Koh Samui is the most developed of Thailand's family-friendly islands. It has an international airport, a full-service Bangkok Hospital, several international schools, and a large, established expat community. Bophut and Maenam on the north coast have a relaxed, village feel ideal for families. It costs more than Koh Phangan but offers meaningfully better infrastructure.
Action checklist
Concrete steps to make this move happen, in order.
Click any step to jump to that section ↓
- 1Apply for the DTV at a Thai embassy before travelling — required for any stay beyond the initial tourist visa period
- 2Contact international schools (ISS, ACE) directly and apply 2–4 months before your intended start date
- 3Arrange international health insurance that includes Bangkok Hospital Samui and emergency airlift to Bangkok
- 4Research neighbourhoods before arrival: Bophut and Maenam are the established family areas on the north coast
- 5Find accommodation through a local property agency or online search before arriving
- 6On arrival: ask your landlord to file the TM30 address form with immigration within 24 hours
- 7Open a Thai bank account at Bangkok Bank's Samui branch — requires a non-immigrant visa and rental contract
- 8Arrange transport: Koh Samui has no public transit — a reliable car or motorbike is essential for families
- 9Plan around the monsoon season (Oct–Dec): the east coast gets the worst weather; Bophut and Maenam are more sheltered
Family fit
Great for
- Families who want island living without sacrificing infrastructure
- Parents who need reliable international schooling on the island
- Frequent travellers (Samui has a regional airport with direct flights to Bangkok and beyond)
- Families transitioning from a higher-cost Asian city like Singapore or Hong Kong
Watch out for
- Higher cost than other Thai islands — housing prices have risen significantly since 2020
- Monsoon season (Oct–Dec) brings heavy rain and rough seas on parts of the island
- Traffic on the ring road can be busy; motorbike safety concerns apply
- Island isolation — for major specialist medical needs, Bangkok remains the destination

Tourist Visa / Visa Exemption
Most Western passports receive 30 days on arrival, extendable once. Koh Samui has its own immigration office.
DTV — Destination Thailand Visa
Recommended for families planning extended stays. Requires proof of remote income and $15,000 in savings.
Tourist Visa — arrival and extension
- Most Western passport holders enter Koh Samui on a 30-day visa exemption at the airport — no advance application required.
- You can extend once for 30 more days at the Koh Samui Immigration Office in Na Thon (cost: ~$53). Queue early — it is busy.
- Not suitable for long-term stays. You cannot open a bank account, sign a long-term lease, or enrol children in school on tourist status.
- For a first scouting trip it works well — but start your DTV application before you arrive if you plan to stay.
DTV Visa — how to apply for Koh Samui
- The DTV (Destination Thailand Visa) is a 5-year multiple-entry visa with 180-day stays, launched in 2024 for remote workers and their families.
- Apply at a Thai embassy or consulate in your home country before travelling — you cannot apply on the island.
- Requirements: valid passport, proof of remote income or business, and evidence of approximately $15,000 USD in savings.
- After arriving on Koh Samui, ask your landlord to file the TM30 address registration form with immigration within 24 hours.
- You must file a 90-day address report every 90 days — do this online at imm.immigration.go.th or in person at the Na Thon Immigration Office.

- Thailand has no residency permit system for foreigners — your passport and current visa stamp are your documents on the island.
- Your landlord must file a TM30 form (address registration with immigration) within 24 hours of your arrival — ask them to confirm this was done.
- All visa holders must report their address to Thai immigration every 90 days. File online at imm.immigration.go.th or in person at the Koh Samui Immigration Office in Na Thon.
- Keep copies of all visa stamps, extension approvals, and 90-day receipts — officers ask for them during renewals.
- For banking, school enrolment, and admin, your passport and current visa stamp serve as your complete identification.
Do your 90-day report online at imm.immigration.go.th — saves a trip to the immigration office in Na Thon.
Banking
- Bangkok Bank and Kasikorn Bank (KBank) both have branches on Koh Samui — Bangkok Bank is generally more accommodating for foreign visa holders.
- To open an account you typically need: passport, non-immigrant visa (DTV or similar), and a rental contract as proof of local address.
- Use Wise or Revolut for receiving international income and converting to Thai Baht — bank wire fees are high.
- ATMs are widely available across the island; markets and smaller shops are still largely cash-based.
- Keep $14–$56 in cash on hand at all times for local transactions.
Bangkok Bank's branch on Koh Samui is the most established for expats — bring your passport, DTV visa, and rental contract.
Housing
Koh Samui is more expensive than Koh Phangan or Chiang Mai, but still very affordable by Western standards. A 3-bedroom villa near Bophut or Maenam rents for $700–$1,800/month. Long-term rentals (6–12 months) often come with significant discounts.
Where to search
These are the main platforms used to find long-term housing on Koh Samui.
Search 'Koh Samui' inside each platform to filter local listings.
Tip: spend 2–4 weeks in a short-term rental on the north coast (Bophut, Maenam) before committing — it is much easier to find a good deal once you are already on the island.
Typical monthly rents
- 1-bed condo or apartment, Bophut / Maenam: $330–$560 / month
- 2-bed house, north coast family areas: $560–$1,060 / month
- 3-bed pool villa, Bophut / Maenam / Plai Laem: $1,110–$2,080 / month
- Furnished short-stay apartment (bills included): $700–$1,530 / month
Best areas for families
What you need to rent
- Passport and current visa stamp
- 1–2 months security deposit in cash
- Monthly rent is usually paid by cash or Thai bank transfer
- Rental contracts are often bilingual (Thai and English) — read both versions before signing
- Ask your landlord to file the TM30 address registration form with immigration within 24 hours of your arrival — required by Thai law
Schools
Koh Samui has several international schools serving the expat community. Options are limited compared to a major city, but quality is solid and fees are very affordable.
Public system
Thai government schools on the island teach entirely in Thai. Not suitable for most expat children without extensive Thai language support.
International options
Two main accredited international schools serve the English-speaking expat community on Samui: ISS and ACE. Both cover Early Years through secondary. The schools are small by international standards, which some families see as a positive. For IB or British A-Level, families typically board their children in Bangkok or Chiang Mai.
Language notes
English is the language of instruction at both main international schools. Thai language classes are included in the curriculum. The expat community on the north coast communicates almost entirely in English.
Options are limited — contact schools early, as class sizes are small and spots fill quickly.
Education options
British / Cambridge curriculum international schools
Small selection of accredited schools serving the island's expat community. Limited capacity.
Childcare
Koh Samui has more childcare options than Koh Phangan, with several licensed nurseries and a large pool of experienced Thai nannies.
Daycare & nurseries
- Private nurseries operate in the main expat areas on the north coast — a smaller selection than a mainland city but generally sufficient
- Typical fees: roughly $196–$504 / month; bilingual (English/Thai) programmes are available at most private nurseries
- Most nurseries accept children from 18 months old
- Visit in person — quality and English fluency of staff varies; community recommendations are your best guide
Nanny & au pair
- Full-time Thai nannies are widely available — typically $336–$588 / month for a live-in arrangement
- Part-time nannies: roughly $5–$7 / hr
- Many nannies have worked with expat families for years and have community references
- English fluency varies — build in a settling-in period and use vetted community referrals
Where to find childcare
- Search 'Samui Expats' on Google — most common starting point for nanny referrals on the island
- Search 'Samui Families' on Google — family-specific group with local recommendations
- Search 'Koh Samui International Community' on Google — broader community group
- Local property and relocation agencies sometimes maintain nanny referral lists
Healthcare

- Bangkok Hospital Koh Samui has a 24/7 emergency department, specialist clinics, and English-speaking doctors — the best medical facility on the island.
- For routine GP visits, children's appointments, and minor emergencies it is generally reliable and fast.
- For serious emergencies — complex surgery, major trauma, or difficult births — medical evacuation to Bangkok is typically required. Most expats arrange dedicated medevac (medical evacuation) insurance.
- Bangkok Hospital Samui can arrange emergency airlift to Bangkok through their partner network — the flight takes roughly 1 hour.
- Pharmacies are well-stocked across the island for everyday medications.
Arrange medical evacuation insurance that covers airlift to Bangkok — affordable and removes the biggest healthcare risk of island living.
Safety
- Violent crime against residents is rare — the family-oriented north coast (Bophut, Maenam) is calm and low-crime.
- Road safety is the biggest daily risk: the ring road is busy, local driving standards vary, and motorbike accidents are common among expats. Use a car where possible, especially with children.
- Water safety matters for families with young children — some beaches have rip currents and seasonal jellyfish. Check local conditions before swimming.
- The Chaweng and Lamai areas are busier and noisier than the north coast — less suited to family daily life.
- Petty theft occurs in tourist-heavy spots — keep bags secure and avoid leaving valuables visible on the beach.
FAQ
Is Koh Samui good for families?
Good — especially for families who want beach life with more infrastructure than Koh Phangan. Better hospital, more school options, and a wider range of restaurants and services.
How much does a family typically need per month here?
Budget $3,000–$5,000/month for a family of four. Rent for a 3-bedroom villa runs $1,200–$2,500/month. International school fees are the largest single cost.
Is housing hard to find here?
Moderate. Popular areas like Bophut and Maenam have consistent availability, but quality villas move quickly. Start searching before you arrive rather than on landing.
Do children need international school here, or can local schools work?
International school is required. Thai government schools teach entirely in Thai and are not suitable for expat children. There are a handful of English-language international schools on the island — check availability and capacity before committing to a move.
Is healthcare easy to access as a newcomer?
For most day-to-day needs, yes — Bangkok Hospital Koh Samui has 24/7 emergency care and English-speaking staff. For complex surgery or specialist cases, Bangkok is the right destination. International health insurance with medical evacuation coverage is strongly recommended.
Do you need a car on Koh Samui?
Yes. There is no public transport on the island. A car is the practical choice for families — essential for school runs, grocery shopping, and daily errands.
How difficult is the paperwork and bureaucracy after moving?
Simple. Same as all Thai destinations: no residency system, no local ID needed. Keep your visa current, complete 90-day address reports to Thai immigration, and ensure your landlord files the TM30 (address registration form) within 24 hours of your arrival.
What usually surprises families after arrival?
How expensive it feels compared to Chiang Mai or the mainland. Samui's popularity with tourists has pushed housing costs up significantly — families expecting typical Thai prices are often caught off guard. Budget accordingly.
